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.

Lay the foundation for multiplication by introducing your second graders to the concepts of skip counting and repeated addition. This lesson can be used alongside Up, Up, and Array, or separately to reinforce these important skills.

Students will love working together to create a display that demonstrates understanding of relative length. Use alone or with the lesson Order Up Measurement.
