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

The students will work 9 2 by 2 multiplication problems and find their answers from an ordered list of numbers below that have a different 3-letter word associated with each. Most if the answers will not be used, as there are 24 possible answers and only 9 actual ones. This is a great practice activity. If mistakes are made, it would be obvious, since the incorrect product would probably not be listed. This will help students to self-correct. A bit more fun than simply assigning a bunch of p

This covers division with 2 and 3 digit dividends and a single digit divisor. The first questions provide the traditional algorithm bracket, while the latter part does not. The latter part also has some practical division problems, and some higher-order thinking estimation questions, very similar to those often found on achievement tests. Great for tests, quizzes, collaborative work, and data collection.

This is a check for understanding, or could be used as a learning activity. It makes for a quick data collection piece. The "bubble sheet" makes for simple scoring.re

The key to effective estimation is the ability to round mentally. This is a prerequisite skill for all estimation. This quick administered quick scored exercise is a perfect way to assess and/or help students understand the simplicity. They are to each number to the "front-end place". That is a mathematical term for the highest place-value place. No pencil calculation should be necessary, easy-to-cut answer templates are provided, as well as a quick-score quiz.
