When beginning to teach bar modeling, it is important to keep numbers fairly simple and focus on understanding what question is being asked, identifying the part-part-whole relationship, and how to draw the representation of the problem using a bar model.
However, differentiation is key, so this document contains both a pdf version as well as a word document which is editable to enable you to adjust for your students.
This set focuses on the “add to” concept, and contains easy, moderate, and hard problems. Four problems have an unknown result, four have an unknown change, and four have an unknown start number.
After students read the cards, they can write their answer statement, and draw their model on a separate sheet of paper. (I often use blank paper.)
These are great as independent practice and as part of cooperative learning centers.
Enjoy the Math!
