Making mistakes helps us learn! Your students will flex their analytical muscles to pinpoint errors in multiplication problems using arrays. Use the lesson on its own or as support to Base Ten Arrays for Multi-Digit Multiplication.

In this lesson, students use cubes to build arrays to represent factor pairs of numbers within 100. They use this understanding to identify multiples as well.

Students will solve area problems by multiplying side lengths for rectangular shapes in real world contexts.

Start your students on subtracting three-digit numbers with this lesson that breaks the problems down by place values!

Practice calculating perimeter with the placement of carnival-themed games with given rectangular dimensions. Your students will use grid paper to determine the location of all the games they choose to make the perfect carnival.

Go to any length to test your students' understanding of perimeter calculations. Students will use their understanding of the perimeter of rectangular shapes to create rectangles that have different side measurements but equal perimeters.

Teach your students to draw an array using base ten notation to solve multiplication problems with two two-digit factors.

Your students will be at the top of the pack with this lesson that has them identify important information within a word problem.
