Subtracting Tens on an Open Number Line #1

Give learners practice subtracting tens from two-digit numbers with this hands-on worksheet! Geared toward first graders, this worksheet invites students to use a number line to subtract a multiple of ten from a two-digit whole number. To complete each subtraction problem, students will first plot the two-digit number on the open number line. From there, learners will mark the subtraction of each of the tens that make up the second number until they get to the answer. This subtraction strategy helps students by providing a concrete model to visualize finding the difference between two numbers.
