Arithmetic

Description

Find the total number of green squares in an array of three 1 x 4 columns (each column contains four green squares). Since the array consists of 1 x 4 arrays, add by 4's: 4 + 4 + 4 = 12. There are a total of 12 squares.

Arithmetic involves basic operations like addition, subtraction, multiplication, and division. Using visual aids like arrays provides students with tangible ways to understand and explore arithmetic concepts. This collection offers examples that reinforce addition by grouping numbers in arrays.

Seeing multiple worked-out examples enables students to recognize patterns and develop confidence in solving problems independently. Repeated practice and variation help students grasp the concept more fully, ensuring deeper learning.

Teacher’s Script: Let’s look at this example. Notice that there are several columns, each containing a specific number of squares. We can count the total by adding the number of squares in each column. For this array, we add: 4 + 4 + 4 = 12. There are a total of 12 squares.
