As math is considered to be the foundation of every subject, it is essential to lay a strong base for students in primary grades. Addition and subtraction of integers are the two key operations that build upon the foundation of mathematics. Teachers can use various activities to teach students to add and subtract three or more integers effectively.

Here are some activities that teachers can use in their classrooms to enhance their students’ mathematical abilities:

1. Number Line Stomp

This activity is a lot of fun, as it involves physical movement in the classroom. Create a large, life-sized number line on the floor using tape or chalk. Students can stand on the number line, and the teacher can call out a sum or difference that requires them to jump forward or backward a certain number of positions. For example, if the teacher calls out “Start at 5 and move forward six spaces,” students should stomp six times on the number line to land on 11.

2. Integer War

“Integer War” is an enjoyable card game that allows kids to practice their addition and subtraction skills. Divide the class into pairs and provide each pair with a deck of cards with the face cards removed. Each player takes two cards, and the sum or difference of the two cards must be computed. The player with the highest or lowest sum/difference wins that round.

3. Integer Towers

“Integer Towers” is a game that engaged students will enjoy playing. Provide students with small cubes or blocks of different colors, and assign different colors to each integer. Students should construct a tower using the corresponding color blocks for each integer that matches different math problems. For example, if the question is “What is -5 + 6 + 9?”, the student would use red, blue, and green blocks to create a tower.

4. Sign at Sight

This game helps students learn how to add and subtract integers by identifying the signs of the numbers. Create flashcards with positive and negative numbers mixed together. You can do this by having students pick cards from a pile, and they need to quickly identify the sign of the number and add or subtract based on the sign. For example, if the card is -2 + 3 + 4, students would add the 3 and 4 and then subtract the result from -2.

5. Integer Dominoes

Provide students with a set of dominoes with integers written on them. Students should match the dominoes, such as -3 with 5 or -4 with -6. Once students have figured out the matches, they should add or subtract the numbers to find the sum or difference. For example, if the match is 6 and -3, they should add the two numbers to get the solution.

In conclusion, activities that involve physical movement, games, and puzzles are excellent ways to engage children in learning how to add and subtract three or more integers. These activities not only help students practice their mathematical skills but they also make learning fun and easy for the students. Teachers who use these activities in their classrooms will find their students become more comfortable with the concepts of addition and subtraction, thereby laying a strong foundation for their future math skills.
