Today we practice the division started last lesson. We are still putting it in terms of how often is X contained in X to drive the division idea home in your child’s mind.

1. $5a^2$ (because 10/2=5 and a^3/a=a^2, you can also write thi a*a*a/a*a and show that two of the a’s cancel since a/a=1 just like 2/2=1)
2. $4ab$ (because 12/3 =4 and a^3/a^2=a and b/1=b)
3. $3a^2bc$ (same process as described for the last two questions – if you have questions, just leave them in the comments below.)
4. $3a^3b$
