Strip Diagrams (also known as Bar Models) is a problem solving strategy that can be applied to all operations.
Use this resource when teaching your students how to problem solve using strips diagrams (a.k.a. bar models). This method is especially useful for those students who respond better to visual stimuli such as pictures, drawings, or graphic organizers.
The pack illustrates the five basic variations and includes examples of how to apply them to different operations.
Print off a pack for each student to keep in their math folder to reference throughout the year. Or as an alternative, project each poster on the board as you teach each variation.
We have included a download with the title page of ‘Strip Diagrams’ and one with ‘Bar Graphs’. All other pages are the same in each download. Use the drop-down menu to choose which title you would like.

Use addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using drawings and equations with...
Use multiplication and division within 100 to solve word problems in situations involving equal groups, arrays, and measurement quantities, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem.
Solve multistep word problems posed with whole numbers and having whole-number answers using the four operations, including problems in which remainders must be interpreted. Represent these problems using equations with a letter standing for the unkn...
