Print out half-sheets with the Do Now, and also include some celebratory and affirming notes so that students have the opportunity to see their names in writing linked to a specific success they’ve had this week. Consider using individual student shout-outs related to perseverance, sense making, etc., or quoting specific lines that students have written on yesterday’s assessment; avoid praise related to being “smart” or simply scoring highly. Also consider shout-outs or praise related to students’ behavior and attitudes during the week as well (e.g. pair work using sentence starters, quick transitions between activities). Ensure that your praise is affirming and reinforcing the behaviors and attitudes you most care about and that are most aligned to students’ mathematical learning and experience of classroom culture, rather than just finding any praise for the sake of giving praise. You may want to ensure that students whose work/thinking/attitude ● push against systems of has been publicly highlighted on the page feel special; while some students at this age feel uncomfortable with oral praise oppression and promote in front of the whole class, consider the following (these are just suggestions; choose something that feels authentic to justice in your classroom you): community? ● provide clarity and the “what ● When these students enter the room, whisper “make sure you read the opening carefully, since I think you’ll see and how” of engaging in the something interesting!” or “hey, I think I saw your name somewhere… maybe in the opening?” (or whatever feels task at hand? like your personality) ● support and build excitement ● Offer students a sticker to put on their paper or to wear (only if this feels appropriate given your emerging about the instructional relationships with students; some teenagers love stickers, and others find them condescending) goals? ● Instead of distributing the half-sheets at the door or through a paper-passing routine, have them placed on desks before students walk in; add a post-it note with a personal word of encouragement or even a smiley face at the UDL Note: (Consider the following seats of highlighted students ● Print the shout-outs in larger font and post them on a bulletin board guidelines) ● ● 1.2/1.3 Offer alternatives for auditory/visual information (directions) 3.3 Guide information processing, visualization and manipulation 7.1 Optimize individual choice and autonomy 7.2 Optimize relevance, value, authenticity 9.2 Facilitate personal coping skills and strategies Students should read the shout-outs and complete the warmup problem. Ask students to raise their hands and share additional shout-outs for their peers; record these in writing on a bulletin board, piece of chart paper, piece of cardstock, etc., so they are visible the rest of the day. Directions: As you walk into the room, find your stack of papers for the day on your desk. Work independently and silently on the do now question for 5 minutes. Praise: You came in and got right to work! This energy inspires your classmates to do the same. ● I can see that you’re actively trying other strategies, that shows courage in the face of new content. Re-engage Learners: ● What do you think is the first step? Does this problem look like the ones we’ve been doing? Students should be able to create the table of values fairly easily, because they have done so before. If necessary, remind SIOP/LRT Note: them that they can do so using substitution. A very small number of students might need an example, such as y = 4(1) + 3, ● Begin the lesson by sharing but this should be a scaffold of last resort because it effectively gives away a key skill that students should already know the content and language objectives with your students and should feel comfortable applying in any context. Some students may not know what to do if the points they find cannot be plotted on the graph (because they are off the axes); if this is the case, encourage students to start with points ● Introduce, reinforce, or that will fit, like x-values of -1, 0, and 1 in this case, and if they can find enough points that fit, to just use those to draw review the key vocabulary that students will be using in the line. Otherwise, they can expand the graph. the lesson In the warm-up problem, some students may not know where to begin with the second method; if this is the case, ● Make explicit connections provide moral support and encouragement. Use statements and probing questions such as: between today’s content and ● ● ● students’ experiences Make explicit connections between today’s content and previous lessons Explicitly build background where gaps in knowledge/experiences might exist ● ● ● ● ● ● What does your gut tell you about where the line should be? Does this line have a larger or smaller slope than the other two? What do you think that means about what it will look like? Where will this line cross the y-axis? [if students recognize that this line will be steeper and have the same y-intercept, but not know how to represent this on paper] Okay, so if it has the same y-intercept, show me a point that you know will be on the graph. What do you think a slope of 4 means? If the y-value grows by 4 each time the x-value increases, where would the next point be? If nearly half the class appears to be at a loss for an additional method, bring the class back together and ask whether any pairs have ideas they’d be willing to share. Elicit several options without evaluating them (unless the class is truly at a loss, in which case the above questions will be helpful), and then send pairs back to keep working. (7 min) Invite pairs to share their second methods by describing them. Ask follow-up questions like: ● ● ● ● ● ● Did anyone else use a similar method? Did you hear anything in this method that you also did? Did you hear anything in this method that you’re not sure about, and want to learn more about? Do you have any clarifying questions for your classmates about this method? Do you think this method will always work? Why or why not? Did anyone use a different method? What is efficient about that method compared to creating a table of values? As students share, revoice and highlight methods that start with a given point (the y-intercept) and use the slope to find the next point, and connect the two points. Also reinforce methods that cross-check the procedure using intuition or a conceptual understanding of the relative steepness of the line and how it should look as compared to the existing lines on the graph. By the end of this discussion, students should feel confident sketching a graph without creating a table of values. They could do so by eyeballing or by counting up and over from a point that they know, like the y-intercept. Survey: Time: 7 min Content Note: Students are introduced to the overarching task for the lesson by engaging in a whole-class discussion. The discussion ensures that students understand the various aspects of the task well enough to get started on student-led work in the “Explore” instructional activity. In the spirit of maintaining cognitive demand, during the Launch, students are NOT introduced to a particular suggested solution method. Students are positioned with the context they need to drive exploration of solution methods. Learning Environment Note: To what extent does this decision (action, system, arrangement, etc.)…: ● promote relationships in which students are seen and heard as individuals? ● increase equity of access to learning for all students? ● push against systems of oppression and promote justice in your classroom community? ● provide clarity and the “what and how” of engaging in the task at hand? ● support and build excitement about the instructional goals? SAY: We’ve come to the half way point of our summer class. Now, I would love to get your feedback on how I’ve been doing. I told y’all at the beginning and I’ll say it again, my end goal is for you all to succeed and master this content. To help me reach this goal, I wanna hear from you. Directions: For the next 5 minutes you will be filling out a survey. There are 10 questions. Think through the summer so far before you answer. I want your honest feedback so these will be anonymous. Praise: I can tell that you are thinking critically about each answer. Thank you. Re-engage Learners: I can’t improve in ways you want if you don’t provide this feedback. What do you wish I could do better as your teacher? UDL Note: (Consider the following guidelines) ● 1.2/1.3 Offer alternatives for auditory/visual information ● 2.3 Support decoding of text, mathematical notation, and symbols ● 2.5 Illustrate through multiple media/multiple formats ● 3.1 Activate or supply background knowledge ● 3.2 Highlight patterns, critical features, big ideas, and relationships ● 3.3 Guide information processing, visualization, and manipulation ● 7.2 Optimize relevance, value, and authenticity Explore- Making Predictions: Time: 20 min Content Note: Students work independently and/or collaboratively to develop and reflect on strategies for problem-solving. They are encouraged to communicate with precision, using clear definitions in their reasoning, and examining each other’s claims. Check for understanding on the task and how students should engage with one another/what they will produce. SAY: Personalize scripting. Frame the lesson: yesterday, you considered how to create graphs from equations in slopeintercept form, and the day before, learned how those equations were connected to situations. Sometimes, however, we don’t have enough information to determine both a slope and an intercept from a situation (like the example we just looked at). In today’s lesson, we’ll figure out how to create graphs from these new situations, so that we can use them to analyze and make predictions. Provide directions for students to approach the task with their partners. Students make sense of and persevere through problems: They analyze givens, constraints, Consider where/how you would want to break these 20 minutes up. Are there any questions you think may yield a particular misconception as you ANTICIPATE? Are there particular questions that you think students may get stuck on and <META-MOMENT> relationships, and goals. They make conjectures about the form and meaning of the solution and plan a solution pathway rather than simply jumping into a solution attempt. They consider analogous problems, and try special cases and simpler forms of the original problem in order to gain insight into its solution. They monitor and evaluate their progress and change course if necessary. Mathematically proficient students check their answers to problems using a different method, and they continually ask themselves, "Does this make sense?" They can understand the approaches of others to solving complex problems and identify correspondences between different approaches. Learning Environment Note: To what extent does this decision (action, system, arrangement, etc.)…: ● promote relationships in which students are seen and heard as individuals? ● increase equity of access to learning for all students? ● push against systems of oppression and promote justice in your classroom community? ● provide clarity and the “what and how” of engaging in the task at hand? ● support and build excitement about the instructional not be able to move forward? These may be natural places to bring students back together as a class before the end of 20 minutes. If students are working productively during the whole block (and they eventually will after doing this routine so many times) chunking may be less necessary. Most students will struggle to work continuously for 20 minutes, especially if they are frustrated. Bringing students back together can help students get ideas to sustain their thinking and move their progress forward. Directions: For the next 20 minutes you will work with a partner to make it though our explore worksheet. This should be at Partner level volume. We will be coming back together at times throughout to check in so listen for me call back. Praise: “You are pushing through confusion. That perseverance will carry you through.” “XYZ is showing their partner their strategy. This collaboration helps us all learn together.” Re-engage Learners: “Which problem are you going to do first?” “How do you think point slope and slope intercept form relate? What can that show us?” Support students to focus on the conceptual and persevere through problems. As they work, they’ll likely struggle with the equations they’re being asked to write, because unless they remember how to create equations in point-slope form from the year, they’ll have had nothing this summer to help them do so. Encourage students to try and come up with a method, or to make a prediction for how they might approach the equation. Students may use their graphs to find the intercept, and then construct an equation in slope-intercept form; this method should be affirmed for creative thinking and applying prior knowledge even though it isn’t ultimately the method students should learn in this lesson. The struggle during this phase is intentional, because it will help students recognize that there are things they do know and can figure out—like how to graph—and places where more information might be helpful. Probe and extend student thinking with back-pocket questions. Look for student ideas to elevate in Discuss / prepare them to share their thinking, evidence, and reasoning through questioning. While conferring, focus on ensuring that all students can graph successfully so that during Discussion, it’s possible to focus primarily on the equations. Consider asking 1-2 students who finish early to create their (correct) graphs on the board (or on posters, or some other form that is visible to the entire class). If this doesn’t feel like something you’re goals?

This skill hasn’t been formally taught in the summer, but it shouldn’t be challenging to students because of their prior mathematical experience (in middle school and during the past school year); what’s likely to be hard is figuring out what the question is asking, because students may be accustomed to being told to evaluate an expression, or solve an equation, or read a graph. It’s not critical that all students answer this question during Explore, because it’s not the target mathematical objective for today’s lesson, but it is helpful to informally assess, as you circulate, whether most students seem to find this fairly straightforward or if they appear to be completely lost. If the latter, you’ll want to use your flex time next week to do a mini-lesson. Discuss: Formally establish new ideas Time: 20 min Content Note: Students present their strategies to the class in a purposeful sequence (facilitated by the teacher) that supports the evaluation of strategies for validity, accuracy, and efficiency, as well as build on each other to develop powerful mathematical ideas. Use an attention-getting signal to bring class together. Elicit student ideas about the concept at hand. If students have posted their graphs on the board, ask them to present their work by explaining how they created the graphs. If the graphs are teacher-created, simply acknowledge that you saw many correct graphs as you were circulating the room and give students a minute to silently check their answers by comparing key features (before doing this, consider asking what they’ll pay attention to on the public graph and on their graph to make sure they’ve graphed accurately: the intercept, the slope, and key points). You can also consider having various students come up to do different parts of the graph, especially if students were missing some elements, but had others correct. Students listen to or read the arguments of others, decide whether they make sense, and ask useful questions to clarify or improve the arguments. They justify their conclusions, communicate them to others, and respond to the arguments of others. They reason inductively about data, making plausible arguments that take into account the context from which the data arose. Mathematically proficient students are also able to compare the effectiveness of two plausible arguments, distinguish correct logic or reasoning from that which is flawed, and—if there is a flaw in an argument—explain what it is. Learning Environment Note: To what extent does this decision (action, system, arrangement, etc.)…: ● promote relationships in which students are seen and heard as individuals? ● increase equity of access to learning for all students? ● push against systems of oppression and promote justice in your classroom community? ● provide clarity and the “what and how” of engaging in the task at hand? Directions: Now that we’ve completed our explore, let’s come together and discuss the answers. We are going to discuss the explore for the next 20 minutes whole group. Remember our discussion norms (POSTED) when answering and commenting. Praise: “Sharing your answer and strategy takes courage. Thank you for taking academic risks in this class.” “I see that your writing down as someone else shares a different strategy to you. That will help you if you get confused when we are working independently.” Re-engage Learners: “What did you get for number one? XYZ got this.” “Can you restate what XYZ just said?” Refer to the Explore questions to guide student thinking to key observations and ideas about the concept at hand. Focus the discussion on the equations; start with the first problem, and elicit students’ ideas and suggestions for how to create an equation. If students remember how to use point-slope form, or remember parts of it, validate that and build on what they remember. If nobody remembers, they’re likely to share processes of finding the y-intercept from the graph and creating an equation in slope-intercept form, or else have suggestions that are farther off the mark. If this is the case, find value in students’ contributions, even if it is as simple as “I noticed that you found a way to incorporate the slope into the equation, which was an important part of yesterday’s equations too.” Offer “one way I can write the equation is like this” and present the equation in point-slope form: y – 76 = 4(x – 3). Ask whether this looks familiar to anyone, and if so, ask “what about this looks familiar?” Students should recognize the slope—and be able to tell you how you found the slope, given their prior lessons this week—and recognize the point being used. State that this is called point-slope form, which is different from the slope-intercept we’ve been studying, because to write it, we use a point and the slope. Also ask how we could “prove” that the point-slope form of the equation and the slope-intercept form of the equation are identical. Students should know that they can distribute and simplify to transform an equation from point-slope to slope-intercept form, but if they do not, posing this question could easily derail the discussion into a conversation about distribution; if you have seen students distributing successfully, however, earlier in this lesson or in previous lessons, there’s great mathematical value in making this connection. Have students make a conjecture about the concept at hand. <META-MOMENT> This is the CONNECTING phrase of mathematical discussion. ● support and build excitement about the instructional goals? Support students to bridge their thinking to mathematical language where appropriate. Ask students how we would write the equation in point-slope form for #2 and #3; pause for a few seconds of silent thinkUDL Note: (Consider the following time (at least 10), and then ask them to turn-and-talk to their partners to construct the equation.
