Math Unit 3 Early Multiplication
Now that we understand the properties of multiplication like...
Repeated Addition..... 4+4+4+4+4 = 4 X 5
The Commutative Property ..... 4 X 5 = 5 X 4
Ten Rule... 10 X anything is that number + a zero .... 10 x 7 = 70
10 x 47 = 470
10 x 473 = 4,730
AND we know we can use what we know to help us find what we don't know. Like...
9 X 9 = ? We can use 10 X 9 = 90 to help us. Just take away one 9!
9 X 9 = (9 X 10) - 9
OR
9 X 11 = ? We can use 9 X 10 = 90 to help us again! Just ADD a 9!
9 x 11 = (9 x 10) + 9 !
We're ready to memorize! Try watching the videos below from School House Rock or some multiplication math games too!
