Counting a 4 by 3 Array with Repeated Addition

Using arrays to write repeated addition sentences

Intro: Repeated Addition With Arrays

Introducing arrays and repeated addition

This lesson shows how to read an array of objects arranged in equal rows and columns and turn it into a repeated addition sentence, connecting counting skills to the idea of equal groups that leads directly into multiplication.

Overview

Repeated Addition with Arrays

What You'll Learn

Identify an array as objects arranged in equal rows and equal columns.

Count how many objects are in one row, then add that same number once for every row.

Write a repeated addition sentence such as 4 + 4 + 4 to match an array of 3 rows of 4.

Recognize that the same array can be read by rows or by columns, giving two different repeated addition sentences for the same total.

Connect repeated addition to the idea of equal groups, the foundation for multiplication.

What You'll Practice

Viewing dot arrays and writing matching addition statements

Counting groups of equal amounts arranged visually

Translating array models into repeated addition up to 100
