## Match 2-Digit Subtraction Word Problems with Models

Looking for a way to enhance your students’ subtraction skills? Teach Starter has the ideal solution! Download our subtraction model match-up to evaluate and improve your students’ abilities to solve and represent 2-digit subtraction word problems.

## Write Number Sentences & Use Bar Models to Subtract

This resource download focuses on reading and interpreting word problems, identifying the number sentence needed to solve, the bar model that represents the problem, and the solution.  Students will practise using a bar model and the part-part-whole concept to solve 2-digit subtraction word problems. Through this resource, students can fluently subtract within 100 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.

Before student use, the 36 cards should be cut apart and mixed up. Students will work to sort the matching sets. If desired, you can have students record their matches using the symbols in the corner of each card and the student recording sheet. Then, work can be checked with the answer key provided.

### Support Struggling Students

To provide additional support, give completed examples of bar models to demonstrate the part-part-whole relationship shown. Also, using physical manipulatives to model the subtraction can help students solve.
