PRESENTATION OUTLINE
Andrew's Amazing Math Project
Commutative Property: You can switch the numbers around and they equal same number.
4x8=32 and 8x4=32
Array: rows and columns put together to equal a number. Arrays help solve multiplication problems
Distributive Property: If you break apart a number to help you get the answer.
9x7=63
Repeated Addition:
A number repeated again and again for counting
Identity:Anything x 1will equal the same number. 4,444x1=4,444
Number bonds:Use balls of numbers to help solve the math problem.
Repeated Subtraction: When you use subtraction to help you solve a division problem.
12/3=4 12-3=9-3=6-3=3-3=0.
Tape diagrams:Boxes with dots in it to equal a number.
Equal groups: Each group has the same number of dots.
Andrew had 4 boxes of candy at the movies. He went to the movies 4 times and had the same number of candy boxes. How many boxes of candy did he have in all? 4x4=16.
Zero property: Anything multiplied by 0 equal's zero 11x0=0
Tristan has 16 Beyblades. He wants to share them equally with his brother Drew. How many beyblades did they each have?
16 beyblades/2 kids= 8 beyblades each
My favorite model is arrays because arrays help you solve hard math problems.
