Area Model of Multiplication Using Base 10 Manipulatives
Explore two-digit multiplication with your class as they work in groups to build models of two-digit multiplication using base 10 manipulatives. They construct rectangles replacing standard numbers with equivalent place values using the blocks, and then relate their rectangles to the traditional written multiplication algorithm.

Double Your Flavor
Knowing your times tables in one thing understanding them is another. The class demonstrates their understanding of multiplication by skip counting, arrays, and moving manipulatives for the 0, 1, 2, 3, and 4 times tables. They watch a PowerPoint presentation, watch a teacher demonstration, construct a visual image for math facts, and fill in a multiplication chart.

Understand the Commutative Property of Multiplication in Word Problems
Arrays are great for multiplication, but what if a word problem doesn't ask for an array? Learn an effective strategy for visualizing multiplication word problems by using knowledge of arrays to draw diagrams. A brief review of how rows and columns create an array is followed by two examples of diagramming.

Arrays of Food
This lesson is based on video clip 220 from the Count on it! series, however the same problem can be posed with out the video. Learners work independently to determine the amount of dried food they will need for a camping trip. Each child needs to create arrays and use repeated addition to determine an amount appropriate to the number of people in their families.

Array Picture Cards
Arrays are a visual way to practice multiplication and division. Using one of these twelve array picture cards, learners write a multiplication word problem describing what they see. After also recording a multiplication number sentence, they write a division word problem and number sentence.

Risk: Divide and Conquer
Have fun building mathematical proficiency by engaging children in a math game! All you need to do is print the game board, playing cards, and instructions and let those kids have some fun. They move their pieces around the board in order to conquer or take each square, the trick is they can't take a square until they divide double-digit numbers and show their work.

Exploring Prime Numbers
Elementary schoolers explore prime and composite numbers. They use tiles to create arrays and work with a partner to find as many array combinations as possible from their assigned numbers. Pupils create a t-chart of prime and composite numbers and construct a 100's chart to tell if a number is prime or composite.
