Multiplying two-digit numbers can be intimidating, especially if the numbers are large. All that regrouping can be confusing. Which number goes where? And better yet, why?
Help students master multiplication with regrouping using the two latest books from KUCRL: Multiplication With Regrouping: Partial Products and Multiplication With Regrouping: Standard Algorithm. Based on the concrete – representational – abstract (CRA) teaching sequence from the Strategic Math Series, both books apply the same procedures to multiplication with regrouping. The Partial Products book shows students how to break numbers into parts, multiply those parts, and then add the partial products to find the final product. The Standard Algorithm book shows students the shortened way to multiply and regroup. Either way, students not only master multiplication, but come to understand exactly what they are doing and why.
