Big Ideas: Estimating the product of larger numbers helps us make a prediction for the final product and then check our products for reasonableness. Estimating allows students to evaluate the reasonableness of a product. Students can use either rounding or compatible numbers, depending on the numbers given, to estimate the product of whole numbers. This task will build a foundation for students to fluently multiple multi-digit whole numbers using the standard algorithm. Vocabulary: multiplication, estimations, product, rounding Special Materials: grid paper (optional)
