Room 108: Addition With Carrying Over

Help your class discover the commutative property of addition with this exploration of the addition table. By folding and coloring the table, a symmetry is found that directs students to an understanding of this crucial mathematical...

Once your mathematicians can add two-digit numbers, it's time to bring on the three-digit addends. Here are 20 practice problems, each involving two whole-number addends. Learners do not need to regroup for any of these, and they have...

These 25 addition problems each have two 3-digit addends, and many require regrouping. There are three examples to guide learners in all the types of problems they encounter, including the last set of five which have four-digit sums....

Practice adding decimals by completing 26 practice problems. Scholars examine two examples before trying these on their own. They add two and three-digit numbers with decimals, regrouping when needed. Not all numbers have decimals, but...

In this addition with regrouping worksheet, learners add three digit numbers and one digit numbers together with regrouping. Students complete 30 problems.

Zoe needs to back up her music collection, but do her friends have enough space on their computers to help? Find out as you teach your class how to add two- and three-digit numbers with regrouping. Place value is emphasized as both the...

Learning new ways to look at basic addition problems can help young mathematicians better grasp place value, expanded form, and carrying. Watch the instructor add two and three-digit numbers together by breaking each number into tens and...

More practice carrying with multiple digit numbers. This video shows addition of numbers to millions, demonstrating regrouping of numbers and place value.

This video shows several examples on carrying digits to add multiple digit numbers.

In this exercise, students practice multiplication with carrying. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.
