Question

Think about this problem: You have 8 boxes of markers, and each box has 12 markers in it. Show how a student might figure out the total number of markers they have if they only know the math facts for 2’s and 4’s. Draw an array that reflects the problem statement with appropriate labels. Without counting and using material from this week’s lesson, show three (3) different strategies that a student might use to figure out the answer.

Answer 1

To find the total number of markers, a student can use arrays, repeated addition, or multiplication.

Step-by-step explanation:

To figure out the total number of markers, a student can use arrays, repeated addition, or multiplication.

Strategy 1: Arrays

A student can draw an array to represent the number of boxes and markers. They would draw 8 rows and 12 columns, and then count the total number of markers.

Strategy 2: Repeated Addition

A student can use repeated addition to find the total number of markers. They would add 12 eight times:

12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 = 96

Strategy 3: Multiplication

A student can also use multiplication. Since there are 8 boxes and each box has 12 markers, the student can multiply 8 by 12:

8 x 12 = 96
