Instructions

Play through this interactive game to learn about Multiply Four By One And Two By Two Digit Numbers. Suitable for Grade 3, Grade 4, Grade 5.

Main Concepts

Compute products of one-digit numbers and 2-, 3-, and 4-digit numbers without regrouping.

Decompose factors into base-ten units and apply the distributive property, reduce multiplication computations to single-digit multiplications and products of numbers with multiples of 10, of 100, and of 1000.

Multiply two two-digit numbers using strategies based on place value and the properties of operations.

Use diagrams and arrays of the multiplication to develop understanding of multiplication.

Arrays showing groupings of can be used to model (groups of 100’s to show thousands, 10’s to show hundreds and ones to show tens).

Compute products of one-digit numbers and 2-, 3-, and 4-digit numbers with regrouping.

Understand that algorithms for multiplication and division are abbreviations for reasoning about quantities.

Discussion Questions

Before the Game

What do you need to do to the two products to find the final answer? What do you need to do to the product when multiplying with zeros? When multiplying by 1 even in the tens place, what happens to the product?

After the Game

When multiplying in the game a number was sometimes stored to the top side - why did this number have to be stored? What happens with the number that gets stored as you continue to multiply? Why do you have to put a placeholder when multiplying the double digit in the tens place? When using the standard algorithm, why do we add "the zero" when we multiply by number in the tens place?
