Lesson Plan 1 Running head: LESSSON PLAN: Lesson Plan: Lisa Burley, Darcia DeLoach, Jackie Garcia, & Jeana McMath University of Phoenix MTE 532 Curriculum Constructs and Assessment: Science and Mathematics Sharon Stone January 10, 2010 Lesson Plan 2 Lesson Plan: In this lesson, we chose the material from chapter 24, "The other convention involves the order of operations: Multiplication and division are always done before addition and subtraction. Since exponentiation is repeated multiplication, it also is done before addition and subtraction. In the expression 5 + 4 × 2 - 6 ÷ 3, 4 × 2 and 6 ÷ 3 are done first. Therefore, the expression is evaluated as 5 + 8 - 2 = 13 - 2 = 11" (deWalle, 2005). Title: Using the PEMDAS System Author: Team A Grade Level: 5 Duration: 3 sessions 45 min. each Overview: Students will be introduced to the proper sequence of operations and will be able to demonstrate mastery of simple algebraic formulas using the PEMDAS model. Standards: TN- Tennessee Curriculum Frameworks Subject : Mathematics Level : Grade Five Standard : Standard 3 – Algebra RemoveLearning Expectation : GLE 0506.3.1 Understand and use order of operations Objectives: Students will be able to become familiar with each step of the order of operations and accurately apply it to various examples. Lesson Plan 3 Resources/Materials: Instructional Activities/Procedures: 1.) Teacher will explain to students that today we will learn how to start writing basic algebra formulas. She will ask the class, “Who can tell me what parts are needed in a sentence?” After answers are taken, she then will ask, “Who thinks it is possible to write a sentence in math?” 2.) The teacher will then instruct students to page. 114 in their Houghton Mifflin text which shows the PEMDAS operations. She will ask for volunteers to read pg. 114 and which explains what the PEMDAS operation is. 3.) She will then write a sample sentence on the board, “The boy ran quickly.” and ask the students what part each word is and how it makes up the sentence. Answers will be taken until students identify the main parts of the sentence such as the subject, verb, adjective, and adverb. 4.) She then will write a basic algebraic formula on the board such as, “(5+4) – (1x2)= “ and state that this is still a sentence except it is written in math. 5.) She will then ask the students to read and repeat after her what each letter stands for “Parenthesis, Exponents, Multiplication and Division, Addition and Subtraction”. Students will then be instructed to copy this down into their math journals. 6.) The teacher will then explain we are going to learn a song to help us remember how to use the order of operations. She will ask if anyone knows the song, “Fere Jacques”. She will then write the 4 steps on the board and explain to the students that they will be singing along to the tune of Fere Jacques. She will start singing, “Parenthesis, Parenthesis, Exponents, Exponents, Multiply, Divide, Multiply, Divide, then Add , Lesson Plan 4 Subtract, Add, Subtract.” She will lead the class in a round robin style singing the steps with the whole class repeating a few times. 7.) When most of the children seem to have the tune and words understood she will then ask the students to stand up at their tables and get ready to start the song. She will then explain that in the order the math sentences are solved you have to move from left to right. She will tell the students as they sing they will need to take one step to the right so they will be moving from left to right until the song is complete. The students will repeat this exercise twice. 8.) Next, the students will return to their seats, and she will demonstrate several problems on the board. The first example will be solving the math sentence she wrote on the board. She will demonstrate with 3 other basic examples. Students will then be instructed to try the first three in their book. 9.) Exit ticket for math, will be their attempts at solving the problems. Day 2 1.) Warm- U: Students will be able to use their math text, math notebooks, and will be passed out drawing paper and asked to draw list the steps of the order or operations. 2.) After warm-up is complete, the students will be asked to stand and sing the song and move to the left. Song will be repeated once. 3.) Teacher will then introduce the acronym, “Please Excuse My Dear Aunt Sally” and explain that if one uses the first letter of the sentence it will help them remember the order operations, 4.) Students will break into groups no more than 4 and worksheets with practice problems will be distributed. Lesson Plan 5 5.) Teacher will circulate around the room and work with groups. 6.) Exit ticket will be a team’s completed worksheet. Day 3 1.) Warm-up will be five practice problems on the board to be completed in math journals. 2.) Students will be handed drawing paper and will be asked to make a poster outlining all the steps of the order of operations and the acronym listed somewhere on their poster. 3.) When students are finished with poster they will begin worksheet with 15 problems to solve. 10.) Assessments: Extension Activities Lesson Plan 6 References deWalle, 2005) Our math book, etc…
