Bring out the pegboards for this one! As you introduce multiplication, explain it as sets of objects using these visual practice problems. Learners look at eight pegboards with varying rows filled. For each, they fill in two sentences using numbers. The first is written in word form: ___ rows of ___. Then, they translate this to a multiplication number sentence: ___ x ___ = ___. Be sure kids understand the difference between rows and columns before starting this, but consider bringing up the fact that it really doesn't matter (commutative property).
