Subtract Using Decomposition: Make a Number Line Model #1

Practice the decomposition method of subtraction in this accessible worksheet! In these six problems, students can solve the subtraction problems by decomposing the subtrahend into tens and ones. Then, they can show subtraction on the number line and calculate the difference. 

This worksheet is intended for second and third graders who are learning different strategies for solving two-digit subtraction problems. Decomposition can help students break subtraction down into easier pieces, and the number line models are useful for visualizing the subtraction problems.
