Activities to Teach Students to Complete the Subtraction Sentence – Up to Two Digits

Subtraction is a foundational mathematical skill that is crucial for students to master. The ability to complete subtraction sentences up to two digits is an essential part of a student’s math education. Not only does it enhance their understanding of fundamental mathematical concepts, but it also builds their problem-solving skills.

Here are some activities that can help students complete subtraction sentences up to two digits:

1. The Fishbowl Game:

The Fishbowl game is a fun and engaging activity that can be played in pairs or small groups. To play the game, students need a fishbowl or a container filled with small pieces of paper with numbers written on them. Each player takes turns picking a number from the fishbowl and then mentally subtracting it from a given number. For example, if the given number is 10, and the number picked from the fishbowl is 3, the student will subtract 3 from 10 to get 7. The player with the most correct answers wins.

2. Mystery Number:

This game is especially helpful for students who struggle with subtraction. The teacher chooses a mystery number between 1 and 20 and writes it on the board. The students take turns guessing the mystery number by subtracting numbers from it. For example, if the mystery number is 10, a student might guess 8 by subtracting 2. The teacher announces whether the guess is too high or too low, and the game continues until someone guesses the mystery number.

3. Subtraction BINGO:

This game is played like traditional BINGO but with subtraction problems instead of numbers. The teacher creates BINGO cards with subtraction sentences up to two digits. The teacher calls out subtraction problems, and students cross out the answers on their BINGO cards. The first student to get a BINGO wins.

4. Subtraction Scavenger Hunt:

In this activity, students search for subtraction problems around the classroom or school. The teacher posts subtraction sentences up to two digits in various places, such as on the chalkboard, on a book cover, or on a sign. Students need to find the problems and write the correct answer on a piece of paper. The student with the most correct answers wins.

5. Subtraction Staircase:

The Subtraction Staircase is a classroom display that helps reinforce subtraction skills. The teacher creates a staircase with the numbers 1 through 20 on each step. Students take turns going up or down the stairs by subtracting or adding a given number. For example, if the student is on step 10 and needs to go down six steps, they subtract 6 from 10 and move down to step 4.

In conclusion, these activities help students learn to complete subtraction sentences up to two digits through engaging, interactive learning opportunities. Subtraction is an essential mathematical skill, and these activities can make it fun and exciting for students to master. By learning subtraction, students also develop their problem-solving skills, which are essential for success in school and beyond.
