Subtraction is an essential skill that students need to master as part of their elementary math curriculum. While traditional methods of subtraction involve borrowing or regrouping, there is another method that is equally effective, which is counting on.
Counting on is a simple and straightforward method that involves starting with the larger number and counting up to the smaller number. This method is particularly useful when teaching subtraction to young students, as it helps them visualize the number line and understand the concept of subtraction.
To help teachers introduce students to counting on, here are five engaging activities to teach students to subtract by counting on – up to 10.
1. Count and Cover Game
In this game, students start by covering ten pictures with counters or small objects, such as buttons or tokens. They are then asked to count how many counters they have covered, and then take away a few from the group. They can then count up from the remaining counters to find the difference. This game can be played in pairs or small groups, and is a great way to reinforce subtraction skills.
2. Number Line Race
The number line race is a fun and interactive game that helps students visualize the number line and understand the concept of subtraction. To play, students are given a number line from 1 to 10 and are asked to start at the larger number and count down to the smaller number. They can then move their marker on the number line to show the difference. The first student to reach the correct answer wins the game.
3. Subtraction Bingo
Subtraction Bingo is a fun and engaging way to reinforce subtraction skills. To play, students are given a bingo card with a variety of subtraction problems. The teacher or a designated caller reads out the subtraction problem, and students must find the answer on their bingo card and cover it with a counter. The first student to get a line or a full card wins the game.
4. Roll and Count Game
In this game, students roll a die and count up to the corresponding number on the number line. They then take away the number of objects rolled on the die, and count up to find the remainder. This game can be played in pairs or small groups, and is a great way to reinforce the concept of counting on.
5. Toss and Subtract Game
The toss and subtract game is a fun and interactive way to teach subtraction skills. To play, students are given a set of small objects, such as mini erasers or small toys. They are then asked to toss them onto a playing surface and count how many objects landed on each side. They can then take away the smaller number from the larger number to find the difference. This game can be played individually or in pairs, and is a great way to reinforce subtraction skills in a playful way.
In conclusion, teaching students to subtract by counting on is an effective way to help them understand the concept of subtraction and visualize the number line. These five activities are engaging and interactive ways to reinforce the concept of counting on and help students develop strong subtraction skills. By incorporating these activities into their lessons, teachers can help their students become confident and proficient in subtraction.
