### PRODUCT DESCRIPTION

Bar Models, Bar Modeling, Strip Diagrams, Tape Models, Word Problem Types. Addition and Subtraction Word Problems

There are eleven types of addition and subtraction word problems. It is very important that students understand how to set up these problems in order to solve them. This resource is a quick look at the types of problems and the diagrams that may be used to solve them.

Students must be able to write an equation before they complete any mathematical computations for any word problem. Unless students set up the problem correctly and have an appropriate equation, they will not be able to solve for the unknown even if they know the appropriate computational strategies.

This is an expanding resources. I will also be adding other bar modeling tips, tricks, anchor charts and desk resources for addition and subtraction word problems.

It currently includes:

* A pictorial summary of all addition and subtraction bar model types relating to all word problem types. (Two different fonts)
* All word problems types with corresponding word problems for reference.
* A combination of the word problem examples and corresponding bar models for all word problem types.

I use ‘guided math’ in my classroom. I begin my teaching time block teaching/spiraling math concepts as a whole group, but most of my math block is devoted to guided practice in small groups followed by independent or small group practice, centers and intervention. I begin my math time every day with a page from my popular Number of the Day series. You may find more math in this “printable” format in my store.

I hope that you and your kids enjoy this fun back-to-school resource. Check back soon. I continue to add Number of the Day units daily!
