Chapter 2.4
Repeated addition with arrays
What You'll Learn
Recognize arrays as organized groups of objects arranged in rows and columns
Connect visual array models to repeated addition expressions
Count equal groups in arrays to build addition statements
Understand that arrays show the same number added multiple times
What You'll Practice
1
Viewing dot arrays and writing matching addition statements
2
Counting groups of equal amounts arranged visually
3
Translating array models into repeated addition up to 100
Why This Matters
Arrays help you see the structure behind addition and prepare you for multiplication. This visual strategy makes mental math easier and builds the foundation for understanding rows, columns, and equal groups in everyday situations like organizing items or counting collections.
