An infinite number of practice worksheets! Every time you open this file, a brand new set of practice problems will be generated, different each time! This addresses the specific "zero in minuend" that so many students struggle with. Some have regrouping necessary in the ones place,. some don't. Great for Compare/Contrast! Use for collaborative learning when a team of students assign portions to members, with a final collaboration/"team check".

Needed: Clean egg cartons and a zip bag with a handful of the children's favorite breakfast cereal. Instructions are included. This is a great manipulative activity, perfect for getting the concept of division into the minds of your students. Cocoa Puffs, Trix, or Fruit Loops work well.

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!

This is an easy to check assessment or check for understanding. It covers basic multiplication computation using 2 digits multiplied by 1 digit, including estimation skills. Great for think-pair-share, graded assessment, or exit pass. Multiple choice with a small "bubble" area makes quick visual checking a breeze!

This is a 20 question assessment, all multiple choice, involving the basic concept of multiplication. Not intended to be a computation assessment, this question set assures understanding of what multiplication actually is. Included is a bubble sheet with a cut/punch out key for easy scoring. Great for collaboration, pretesting, and assessing understanding.

A new worksheet every time! A new matching key every time! These are great for practice, homework, centers, week-long assignments, and cooperative learning/collaboration. Assign to teams, they can decide how to share the workload, and they can get together on the answers, and they can find errors and work together to correct them. 2 pages, 12 on a page 24 problems total. (Preview only shows one page.)

This will give you a different worksheet each time you open, with key! Infinite different worksheets! 24 practice problems with room for the students to check. The BEST way to achieve mastery in this difficult algorithm is to begin with 2-digit numbers. Look for my 3-, 4-, 5-, and 6- digit worksheets. Keys are included!

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.
