Intro to Counting in Groups (Arrays)

Each number is 5 more than the number before it. 5, 10, 15, 20, 25, etc.

Each number is 10 more than the number before it. 10, 20, 30, 40, etc.

When you skip count by 5s, you add 5 each time.

I add the first two together. Then I add the last number to the sum.

12

Repeated addition is adding the same number over and over again. For example, 3 + 3 + 3 + 3 is repeated addition.

A row is a group of objects in a line. Rows go left and right.

An array is a group of equal rows that are lined up.

There are 4 dots in each row. Add 4 + 4 + 4 = 12.

Add 5 + 5 = 10.
