It's not enough to just memorize the multiplication table! It helps students to know how to explain their strategy to find the product too. Teach this lesson on its own or use it as support for the lesson Slap and Roll Timed Multiplication.

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.

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.

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.
