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...

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 worksheet. They fill in missing numbers on a number line to complete each sequence, adding or subtracting 10. There are two addition...

These addition and subtraction problems probably aren't written the way your scholars are used to seeing them, especially since they have double-digit addends and subtrahends. This set of eight horizontal equations gives learners a...

Although this worksheet says it contains addition and subtraction within 20, it doesn't. Learners will have to add and subtract double-digit numbers with answers up to at least 30. However, it does provide good practice.

Break down addition and subtraction into short sentences using this brief learning exercise. Each question prompts scholars to make a number by doing three math operations. For the first, they make 10 by adding three, adding five, and...

Here are some practice problems with adding and subtracting three-digit numbers. Scholars complete three addition problems and three subtraction problems. None of these involve carrying over or regrouping. There are only two numbers 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...
