In this topic, students will:
use patterns to find products when one factor is a multiple of 10
use different strategies to find products when one factor is a multiple of 10
use the properties of multiplication to find products when one factor is a multiple of 10
At-home Practice:
Supplies:
a deck of cards (remove face cards)
paper and pencil
Divide the deck evenly between players. Player one flips over two cards and multiplies them. Player 1 then makes one of the numbers a multiple of 10. He/she should then multiply the cards using the new number. (ex. Player 1 flips over a 7 and 4. He/she multiples 7 x 4 = 28. He/she then makes the 4 a 40 and multiplies 7 x 40 = 280.) Player 2 repeats the same steps as Player 1. Compare the products (answer). Whoever has the larger product wins all the cards. Continue playing until one player has all of the cards.
