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 be able to find all of the factors pairs of whole numbers up to 100 and decide whether a given whole number, within 100, is a multiple of a given one-digit number.
To begin, tell students that this lesson focuses on multiplication.
Ask students to share what they already know about multiplication. If you have already been studying multiplication, build on that, but if you have not, just let students share what they generally know.
Explain that today's lesson will involve pairs, which you will introduce in a moment. Ask students to give examples of pairs.
