Number Strings- Adapted from Minilessons for Math Practice (Bresser and holtzman, 2006)

1. Record a number string on the board for students to solve (ex. 5 + 2 + 5)

2. Allow a minute or so for students to solve the problem.

3. Elicit answers and strategies from a few volunteers and record students' strategies on the board.

4. Using a new number string, repeat steps 1-3, this time asking students to share their strategy with a partner before you lead a class discussion.

Key Questions

• What strategy did you use?

• Can you find any familiar number

combinations?

Common Core Standard: 1.OA.3 Apply properties of operations as strategies to add and subtract. Examples: If 8+3=11 is

known, then 3+8=11 is also known. (Commutative property of addition.) To add 2+6+4, the second two numbers can be

added to make a ten, so 2+6+4 = 2+10=12. (Associative property of addition.)

I am always looking for fun, simple, interactive ways to do math with my kinders. I especially like activities that they can become independent at, but produce something so parents can see what we've been working and I can evaluate student progress. And, like my students, I am very tired of pages that require them to show what they know by coloring. COLORING IS

BORING! Five year olds like to DO

things, and by golly I am going to give them what they want! So my students learned how to decompose numbers in a hands-on experience with unifix cubes, and then continued to develop the concept using 1" squares of construction paper in a

representation of the cubes. They glued the squares into
