Many families have asked me about the types of math we are doing in class these days. I'll take this opportunity to update you about what we did in math yesterday: defining math strategies. 

We focused on a few, namely:

The Five is Half of 10 Strategy
If given the problem 5 x 78, it is easier for many to solve 10 x 78 first, and then divide it in half to find your product. 

The Fifty is Half of 100 Strategy
To solve 50 x 78, it is easier for many to solve 100 x 78 first, then divide it in half to find your product. 

The Over Strategy
If you are trying to solve a problem like 49 x 78, it may be helpful to start with 50 x 78 and then subtract one group of 78. 

The Partial Products Strategy
When working on a problem like 99 x 3, it may be easier to solve it in parts: (90 x 3) + (9 x 3)

We will continue to practice these and other strategies this year, and for the next couple of weeks in particular. Ask your child to locate these strategies in use on their homework pages!

  1. This is SUPER helpful, Maureen -- I was wondering what strategies the kids were learning. :-)
