Description
Use addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and 5 columns; write an equation to express the total as a sum of equal addends
Mastery Evidence
- Count objects in a 3×4 array and write 4 + 4 + 4 = 12
- Explain that each row has the same number of objects so the total can be found by repeated addition
- Draw a rectangular array to model a given repeated-addition equation
Assessment Prompt
If your child sees 4 rows of 5 stickers on a sheet, can they use repeated addition — '5 + 5 + 5 + 5' — to find the total, and write it as an equation?
