Build-the-Greatest-Product

Build-the-Greatest-Product is a Grade 4 multiplication game in which every digit placement affects the final product. Players build multiplication problems from drawn cards, decide where each digit should go, and calculate the product once the form is complete. The goal of making the greatest product encourages students to reason about place value before they multiply.

Use it in a small group when students are practicing the multiplication algorithm and developing a better sense of how factor size influences a product. Have students compare strategies and identify which place-value decisions mattered most.
