# Activities to Teach Students to Subtract Two-Digit Numbers – With Regrouping

For many students, subtracting two-digit numbers can be a challenging task, especially when regrouping is necessary. As educators, it is our responsibility to provide our students with effective ways to master this skill. In this article, we will discuss some of the activities that can help students subtract two-digit numbers with regrouping.

1. Base Ten Blocks

One of the most effective ways to teach subtraction with regrouping is by using Base Ten Blocks. These blocks can help students visualize the values of each digit and understand how they are added or subtracted. To use Base Ten Blocks, students separate the ones, tens, and hundreds using blocks. Once they have done this, they can subtract the numbers from the ones place before moving on to the tens place. If the subtraction requires regrouping, students can change ten ones to one ten and continue subtracting.

2. Number Lines

Another way to teach subtraction with regrouping is by using number lines. This method can be used with or without Base Ten Blocks. Students can use the number line to subtract the numbers and understand the concept of regrouping. For example, for a problem such as 62 – 28, a student would start at 62 and move back 8 and then jump back 2 more to reach 34.

3. Math Games

Math games are always a great way to teach students subtraction with regrouping. These games can make learning fun and engaging. Some popular math games for subtraction with regrouping include:
– War: In this game, students draw two-digit numbers from a deck of cards and subtract them from each other. The person with the highest answer wins the round.
– Bingo: Create a bingo card with two-digit subtraction problems and have students solve them. The first one to complete the card wins!
– Race to Zero: In this game, students start at 100 and race to subtract numbers from each other to reach zero. The first one to reach zero wins the game.

4. Worksheets

Worksheets are a great way to reinforce subtraction with regrouping skills. These can be done in class or given as homework. Teachers can find various subtraction with regrouping worksheets online, or they can create their own. Students can practice subtracting two-digit numbers in various scenarios such as word problems, subtraction with borrowing, and more.

In conclusion, teaching subtraction with regrouping can be challenging, but the above activities can help make it more enjoyable and easily understandable for students. By using Base Ten Blocks, Number Lines, Math Games, and Worksheets, students can develop problem-solving skills while having fun. Teachers should present these activities in an engaging way to make sure that students have a good understanding of the concept.
