## Race to 200: A Game Focused on Student Computation & Strategy

by

April 13th, 2017How do you combine computation skills and a game in the same setting? The game Race to 200 helps students, and their partners, build their understanding of number computation, number sense, and place value. This game can be played during one class period, but we recommend trying all three versions, over three periods, so students can…

## Making Math Homework Count

by

March 10th, 2017What constitutes good and meaningful math homework? Through a rich bank of math homework assignments, teachers come to see how homework can reinforce skills, prepare students for future lessons, extend their mathematical knowledge, and inspire their creativity. Take this example: Homework: If 3 is 5% of a number, what is 30% of that number? …

## Halving Squares: A #FractionsFebruary Activity

by

February 21st, 2017An important mathematics concept for children to learn is that all halves of the same whole are the same size. If the whole is divided into different sizes, then they are not halves. While halves of the same shape must be the same size, they do not have to be the same shape. For example,…
