Beat the Bank Multiplication
multiplication · multiplying a 3-digit number by a 1-digit number and comparing product to 2000
To multiply a 3-digit number by a 1-digit number [4.NBT.B.5].
Beat the Bank Multiplication is a Grade 4 game that combines multi-digit multiplication with estimation. Students use dice to create a three-digit-by-one-digit multiplication problem, predict whether the product will be above or below 2,000, and then calculate to check. That prediction step encourages students to think about product size before relying on the algorithm.
Use it in a small group when students know how to multiply but still need stronger number sense around reasonable products. Ask them what information helped them make the prediction and how they could tell whether an answer is plausible.
