4.05 Patterns

Lesson

Are you ready?

We've seen how multiplying by $2$2 helps us multiply by $4$4, and then by $8$8. Let's try this problem to help us remember. 

$6\times8$6×8

 

Learn

What if we could use things we already know to solve multiplication or division? We can! Let's see how.

Apply

If $2\times8=16$2×8=16, what is $20\times8$20×8?

 

Remember!

For every multiplication problem we know, there's another one we also know! If we know our $3$3 times tables, including $3$3 × $7$7= 21, then we know that $7$7 × $3$3= $21$21.
