Add and Subtract

Do you add or subtract? It's up to your mathematicians as they fill in the symbol for 16 equations to make them true. The numbers in this section don't exceed 18. Next, learners answer six word problems by determining the missing addend...

Find the missing digits in these number sequences. Each of the ten has one missing number and scholars must figure out what it is. Here's the pattern: all of these sequences involve counting by 10s. Learners add or subtract 10 to...

In this adding and subtracting activity, students use counters or connecting cubes to help write addition and subtraction sentences. Students solve six problems.

In these twenty pages of addition and subtraction problems worksheets, students subtract one-digit from one-and two digits, add one-digit plus one- and two digits, and both add and subtract to problem solve. Students solve 200 problems.

Get your mental mathletes in top form with this number sequence worksheet! They must add or subtract 10 from a number to complete these number lines, finding the missing three-digit numeral from a list of answers. Encourage verbal or...

Here are some number lines that need to be completed. There are two number sequences, one to test addition skills and the other for subtraction. Both sequences include counting by 10, but the subtracting question has scholars count...

Give your mathematicians some practice with three-digit numbers as they complete these addition and subtraction problems. There are six vertically-formatted equations to start, then learners add to and subtract from eight numbers...

Don't let the title of this one fool you; scholars skip count only by 10 in this number sequence learning exercise. They fill in missing numbers on a number line to complete each sequence, adding or subtracting 10. There are two addition...

Solve these true equations; scholars examine three-digit addends, subtrahends, and minuends in these equations that are each missing one number. There is a list of possible answers to choose from, so decide whether or not you want to...

Given a number between 10 and 99, learners use place value and properties of operations to add and subtract 10. The goal is to have them mentally calculate the number, and to refrain from counting or using manipulatives. Learners explain...
