This is a center I made to use as a math center during my guided math centers. Multiple copies could also be made and it could also be used as an activity during whole group instruction. Can be done by a small group, pairs, or as an independent activity. This primary objective of this activity is to promote multiplication practice and to match factor pairs that have the same products. Students have to identify the factor pairs that yield prime numbers and put them on the edges of the puzzle while matching the factor pairs that are composite to the corresponding factor pair with the matching product. This activity also helps students apply divisibility rules to help them find if their factor pair has a product that is prime or composite. Students need to know how to multiply up to two-digit numbers by one-digit numbers in order to do this activity.
