Activities to Teach Students to Complete the Subtraction Sentence – Up to 18

Subtraction is a fundamental math skill that every student must learn. One of the most important aspects of subtraction is learning to complete the subtraction sentence. This means that students are able to correctly identify the two numbers involved in the subtraction problem and the difference between them. While some students may find this concept easy to grasp, others may need some extra help. Here are some activities that can help students to complete subtraction sentences up to 18:

1. Roll-and-Write:

Students love any activity that involves rolling dice. For this game, you will need two dice, a sheet of paper, and a pencil. Ask students to roll the dice and write the numbers down. Then, ask them to complete the subtraction sentence by finding the difference between the two numbers. This activity not only reinforces the concept of subtraction but also helps with computation skills.

2. Subtraction Bingo:

This game is a fun and interactive way to teach subtraction. You will need bingo cards with subtraction problems and chips or markers. Students can mark the answers on their bingo cards and play until someone wins. For students who are struggling with subtraction, you can provide them with manipulatives such as beans or cubes to help them visualize the subtraction problems.

3. Subtraction War:

This is another game that uses dice. You will need two dice, a sheet of paper, and a pencil. Students take turns rolling the dice and subtracting the smaller number from the larger number. The student with the highest difference wins that round. This game not only helps with subtraction skills but also with comparing numbers.

4. Subtraction Story Problems:

Using story problems is an effective way to teach students how to relate subtraction to real-world situations. You can make up your own story problems or use pre-made worksheets. For example, “Samantha had 12 crayons. She gave 4 to her friend. How many crayons does Samantha have now?” This activity helps students to understand the concept of taking away.

5. Subtraction Videos:

Finally, you can use subtraction videos to help students learn. There are many educational videos available on YouTube that teach subtraction through songs and visuals. You can also create your own videos to cater to the specific needs of your students.

In conclusion, completing subtraction sentences is an essential skill that every student must learn. These activities can help students to grasp the concept of subtraction and find the difference between two numbers up to 18. By incorporating fun and interactive games and visuals, students will not only learn the skill, but also have fun doing it!
