What better way to estimate then to be given the EXACT answers to a set of paired numbers to be added or subtracted? Estimation is not about steps. It is about using whatever mental mean necessary to find a close answer quickly. ESTIMATION: AN EASY WAY TO FIND AN ANSWER THAT IS CLOSE. This matching worksheet gives 9 pairs of numbers from 3 to 6 digits which are either added or subtracted. The exact sums and differences are on the other side. Estimation strategies will make this simple for your

Create an infinite number of worksheets! Just open the file and you have 9 problems that require regrouping...WITH A KEY. Close and re-open and you have a different set of practice items! Look for my 2-, 4-, 5-, and even 6- digit practice sheets. THANKS FOR USING!

EVERY TIME you open the document you will get a different worksheet. Great for practice, group seat work, collaboration (assign to a team and they work together or designate portions with team consensus). Easy to produce for ISS. Room for check with addition. Key is included!
