Math Replacement Update January 15, 2015 Topics Covered Topics Covered Students learn and apply a four-step approach that can be used to solve number stories. They focus on addition and subtraction number stories. Students use what they know about the total number of degrees in a circle and the relationships among angles to determine the size of various angles. Students review the meanings of number sentences and determine, whenever possible, whether number sentences are true or false. Students learn definitions for acute and obtuse angles and review other types of angles. They use the Geometry Template to measure and draw angles. Students review the use of parentheses in number sentences that involve more than one operation. They determine whether number sentences containing parentheses are true or false, and they insert parentheses to make true number sentences. Students define equilateral, isosceles, and scalene triangles. Students identify geometric shapes and their properties. They compare and classify quadrangles according to their properties. Students explore regular tessellations and decide which regular polygons tessellate and which ones do not, based on the sum of the angle measures around a single point. Students learn about open sentences and their solutions. They participate in the Broken Calculator activity to reinforce the concept of open sentences and to practice estimation. Topics Covered Students describe a general number pattern in words and write examples or special cases of it. They are given special cases for a general pattern and describe it with a number sentence having one variable. Students examine, describe, and write general patterns having two variables. They identify special cases of such general patterns. Students write and evaluate algebraic expressions for situations described in words. Students examine geometric formulas to see how they can be derived. They use substitution to evaluate formulas and use formulas as rules to complete "What's My Rule?" tables.

Scholastic Math magazine homework due - Feb 1st SPECIAL ANNOUNCEMENT District 95 will be hosting two fun and informative all-family events in February! The Parent Feed + Project B3 is a 90-minute digital responsibility awareness event that parents and students can attend together. Parents will experience The Parent Feed seminar given by social media professional Matt Batt. They will get the latest, most upto-date information on what this “digital generation” is doing online. They will be given information on popular Apps and how kids are using them as well as steps they can take to keep their children’s digital lives under control with an emphasis on safety, future impact and cyberbullying. Students will spend time with local high school student leaders participating in Project B3: Be Safe. Be Smart. Be Kind. They will be lead through fun activities and take part in discussions on what they can do to be digitally responsible individuals, taking an active role in avoiding and combatting risky behavior and cyberbullying. The student program (Project B3) is particularly geared toward students in grades 2-8. We will hold two sessions available to all District 95 families: • February 3rd, at Lake Zurich Middle School North, 7-8:30 pm • February 18th, at Lake Zurich Middle School South, 7-8:30 pm
