Interactive games to teach regrouping
Remind students that when they regroup, they gather ten ones to make one group of ten. Have students trade in 10 cubes for a rod. Then have one person in each group write the number represented by the base-ten blocks. Have students swap roles and regroup different numbers. Addition Stories Have students make up their own word problems or addition story problems.
Encourage them to use amounts that require addition with regrouping. You may wish to model a few examples for the class before having students write and illustrate their own word problems. You may also allow them to use manipulatives such as base-ten blocks or counters to solve.
Then have your child solve the number sentence using pencil and paper. Have your child explain how he or she is solving the number sentence out loud. What is done first? What happens when you carry the one over to the tens place? Guide your child through the process, addressing any questions or misunderstandings, and then try the exercise again with other number sentences. You may want to also have your child write and draw about the steps in an addition with regrouping problem.
Pennies and Dimes Give your child a large collection of pennies and have him or her trade in groups of ten for dimes. In other words, students basically have one year to not only learn but master addition and subtraction. As a former 2nd grade teacher, I know how tedious it can get to spend such a large portion of the year focused on this one skill. Especially because it can be hard to get creative with this particular concept.
Here are some ideas for activities you can use to help your students practice addition and subtraction, with or without regrouping. Because of this, manipulatives such as place value disks and base blocks can be really helpful.
However, constantly using this practice over and over can get old. Switch it up by super-sizing your manipulatives! This can be as simple as using masking tape to create a place value chart on your floor and cutting circles out of construction paper for your place value disks.
Kick it up another notch by using items that your students are interested in , such as balls or stuffed animals. Now you may not have several flying discs laying around like I do, but you can get creative with whatever your students are currently into! Partner match up is a fun game you can play to practice addition and subtraction. It gets students out of their seats and moving as they practice.
To play, each student needs a card with a number on it and a whiteboard. Students will roam around the room play music if you want! Then, students will partner up with the student closest to them. They will show each other their numbers and either add or subtract the two numbers on their whiteboards.
The students will then switch numbers, and the game repeats again. Math hangman is a fun math warm-up that helps build critical thinking skills. It can be used with any basic math operation, including addition and subtraction with regrouping. To play, the teacher will think of a math equation and write it on the board, using blanks instead of the numbers you can leave the operations in. Students will then guess numbers.
As they guess, add correct numbers in the corresponding blanks, and add to the hangman drawing for wrong numbers. As numbers start filling in, students can use their understanding of number sense to help them figure out the rest of the numbers.
