5th Graders will continue to work on new multiplication strategies this coming week. They are in a new learning curve that does not feel completely comfortable yet, but will save them so much calculation time as they familiarize themselves with these strategies. Below is a sample of four of the strategies they will be using. Perhaps you and your child can try these out using various numbers.
The new strategies are:
Using Partial Products through a ratio table:
Doubling & Halving:
25 x 36 50 x 18 100 x 9 = 900
Five is Half of Ten:
Over time, students will become more fluent with these strategies and more proficient mathematicians as they calculate larger numbers.
