Estimation Strategies “Cheat Sheet”

We have been working on estimation this week – there are a number of different ways to use “mental math” to do it. Next week we will review and have a small quiz to check our understanding (only on front end rounding, compensation and compatible numbers). Using the “cheat sheet” below ry to come up with your own examples of these different strategies.

Mental math can be a challenge for some children as it involves the working memory and a strong level of comfort with the partner numbers (this is the part-part-whole concept taught in primary grades). If you think your child could benefit from regular math practice have a look at some of he suggestions in my previous “Math Practice” post.
