Monday----Lesson 5-1 Addition: Doubles
Students will recognize the doubles relationship and use it as a strategy for remembering addition facts with two like addends.
Essential Understanding: Doubles facts can be associated with memorable real-world situations.
Materials: connecting cubes
In this lesson, students work with counters and pictures to represent double addition combinations.
Daily Common Core Review pp5-1 Students will complete 3 review problems before the lesson begins. Teacher will direct students with this activity.

Materials: number cube, counters
Math Background--- In this lesson, students build upon their knowledge of doubles to add near doubles. Adding near doubles can be done in two steps-first doubling the lesser addend, then adding 1 to find the sum. Students who have difficulty with the first step may need more practice with doubles facts.

Thursday--- Lesson 5-4 Problem Solving: Two –Question Problems
Standard: 1.OA.6 also 1.OA.8
Objective: Students will use a ten-frame to write addition facts with 5.
Essential Understanding: Facts with sums 6 through 10 can be broken into 5 plus some number.
Materials: counters
Math Background--- In this lesson, students use a ten-frame to complete addition facts with an addend of 5 and addition facts with a sum of 10. In doing so, students learn to anchor numbers to both 5 and 10. For example, 8 can be thought of as “5 and 3 more” and 2 away from 10.” The relationship of a number to 5 and 10 will help students later as they develop computation skills with greater numbers such as 68+7.

Students will use guided practice on page 130 and independent practice on page 131 to write the addition fact with 5 and then write an addition fact for 10. Problem Solving page 132 Teacher will encourage students to use a ten-frame to solve the problem. Teacher will encourage students to think about what two parts are being added.
Close/Assess and Differentiate: In this lesson you learned that addition is made easier when you can see what is being added together in a ten-frame. When you don’t have a ten-frame handy picture it in your mind. Quick Check Master 5-4.
Friday--- Lesson 5-5 Addition: Making 10 to Add
Standard: 1.OA.6 also 1.OA.8
Objective: Students will use two ten-frames to model addition facts.
Essential Understanding: Ten can be shown in two parts in different ways and represented using addition number sentences.
Materials: counters
Math Background--- Being able to decompose and recompose addends to maintain a constant sum is an important strategy. In this lesson, students use ten-frames to recompose addends into 10 and some more. By moving counters to fill the first ten-frame, students simplify their addition sentences.
