Home Connections Support & Resources
This unit is an INTRODUCTION to multi-digit division. Please REFRAIN from teaching your child the long division standard algorithm. Multi-digit division will be mastered at a later unit this school year.
Building Multiplication Arrays
Building Multiplication Arrays
Below you will find resources to show what happens when a number is multiplied by 10, 100, or 1,000 and how to use base ten area pieces to model and solve single- and double-digit multiplication combinations.
Home Connection Pages:
21, 23, 24, 25, 26BASE TEN PIECES- (Look at this visual to examine the relationships among place values and to make generalizations about what happens when a number is multiplied by 10, 100, or 1,000)
LINEAR UNITS- (Look at this visual to see how linear units are used with the base ten pieces)
BUILDING MULTIPLICATION ARRAYS- (Look at this visual to see how 2-digit by 2-digit multiplication problems are solved by building multiplication arrays with base ten area pieces)
Arrays and Ratio Tables
Arrays and Ratio Tables
Below you will find resources to support moving from building arrays with base ten area and linear pieces to sketching arrays on base ten grid paper to sketching open arrays. Also strategies to multiply single digits by multiples of 10.

Games for Extra Practice:
Games for Extra Practice:
In this Tetris-like game, your child can arrange falling blocks that can be reconstructed into different arrays. Doing so allows them to explore array building and factorization.
Learners make sense of multiplication & division using visual models with arrays in a series of games and activities on this free mobile app.
Your child can become confident in facts up to 12 x 12 using visual models that stress the conceptual aspects of multiplication.
