Partial Products is a mental math strategy for double-digit multiplication. It can be used as a replacement for the commonly-used "long multiplication." The primary reason for teaching this strategy (as with all mental math strategies) is that it will improve your students' understanding of numbers.
Rather than memorizing a series of confusing steps as in long multiplication, students will use their knowledge of place value and the real meaning of each numeral. This resource is divided into two sections so you can differentiate for your students' needs and abilities.
This strategy unit provides all of the resources that you will need for teaching the partial products strategy:
Section 1 teaches 2-digit by 1-digit multiplication.
Section 2 teaches 2-digit by 2-digit multiplication.
Depending on the grade level that you teach, Section 2 might be somewhat difficult for the majority of your class, but may be useful as enrichment for some students.
What Teachers Are Saying
⭐️⭐️⭐️⭐️⭐️ "Great reteaching tool to use with my students with IEP's." Shannon R.
⭐️⭐️⭐️⭐️⭐️ "I loved this product. I think it is so important to expose students to ‘all the ways’ numbers work and can be manipulated. Included is instruction, practice, then reinforcement through (loads of) games to play. We mostly used the games to reinforce the concepts." Spotts Lit
⭐️⭐️⭐️⭐️⭐️ "This is nice additional work to supplement. Thanks!" Catherine Y.
