Common Core Standards:

CCSS.MATH.CONTENT.K.OA.A.3: 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 = 2 + 3 and 5 = 4 + 1).

CCSS.MATH.CONTENT.K.OA.A.4: 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.

Targeted Needs of Student:

Decomposing numbers within 10, understanding balancing both numbers within 10, tactile way of decomposing 10, adding and subtracting numbers within 10, groups of numbers to add

Goal:

Providing students with a tactile way to decompose within 10.

Materials Needed:

1. Styrofoam cups
2. Sharpies
3. Pipe Cleaners
4. Beads

Explanation/Summary:

Student will construct a cup with a pipe cleaner weaved through it to create a loop at the top. On the pipe cleaner, there will be 10 beads that can be easily moved across to show adding numbers up to 10 and subtracting within 10. For instance if there are 6 beads on one side, then students can count the remaining 4 to show 6 + 4 = 10. Or they can show that 10 – 4 = 6. Teacher should have students write equations afterwards.
