1 Kindergarten Chapter 5 - Overview & Support It is suggested to insert Ch. 7 between Ch. 5 & Ch. 6.See Chapter 7 for rationale. Standards: Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from. Represent addition and subtraction with objects, fingers, mental images, drawings 1, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations. K.OA.2 K.OA.4 Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem. Decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition by a drawing or equation (e.g., 5 = and 5 = 4 + 1). For any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or equation. K.OA.5 Fluently add and subtract within 5. Suggested Routines: look in the marginalia at EL Strategy for pre teaching strategies and math journal ideas It is suggested to teach chapter 7 after chapter 5 before teaching chapter 6. The second trimester benchmark math assessment tests addition only (not subtraction) this may alleviate confusion for students who have just learned subtraction. The second trimester math assessment also tests teen numbers which is taught in chapter 7. 1 Drawings need not show details, but should show the mathematics in the problem. (This applies wherever drawings are mentioned in the Standards)

3 Essential Questions: How can you show addition? How can you show addition as adding to and putting together? How can you solve problems by using the strategy act it out? How can you use objects and drawings to solve addition word problems within 10 and complete a written addition sentence/equation? How can you use a drawing to make 10 from any given number? How can you show and write an addition sentence for for sums of 5, 6, 7, 8, 9, and 10? *Refer the essential questions in each lesson to formulate your teaching objectives for the lesson. Students will be able to: -use written numbers to represent addition sentences/equations to 10 -use a drawing to find 10 from any given number and write an equation -solve addition word problems within 10 and record the equation -use the strategy act it out to solve problems -decompose numbers to 10 in multiple ways and record each decomposition with an addition sentence/equation Lesson-by-Lesson Overview: Lesson #, Standard Show What ou Know Title Materials Vocab Notes : Add to : Put Together Act Out Problems whiteboard, math journals add, addition plus, putting together, ten frame, in all is equal to, plus, in all Have manipulatives available to model addition stories. When stating the addition story use, is the same as +. As additional practice, use blank ten frames to model extra putting together stories. Use math journals for additional practice with addition sentences and bar model/tape diagram) Prior to lesson, frontload with sentence frames for retelling addition sentence.

Refer to RTI strategies at the end of the TE chapter 5 Review/Test: Reteach Blackline Masters Math centers/workshop and/or math standards games. Small group instruction focused on a single standard using the Intensive Intervention materials. Whole group instruction focused on a single standard. Use student examples (no name) and correct as a whole group discussing math reasoning. Use that math reasoning to support their corrections and validate their math though processes. Small group math discussion: Use a few problems from the blackline summative assessment guide for Chapter 5. Pull problems that seemed difficult for some students on the Review/Test. Present the each problem and have the groups discuss the strategies to solve the problems. Math standards games and/or technology apps that support specific standards. In small groups, do the Performance Task from the Assessment Book in Go Math! Share strategies and discuss whole class.
