Subtraction is a fundamental concept in mathematics, and every student must have a clear understanding of it. It involves the process of taking away a specific number from a given number to find the difference between them. Subtraction is used in almost all daily activities such as shopping, budgeting, and even in games. However, some students find it challenging to complete the subtraction sentence up to 20. In this article, we will share some activities that teachers can use to help students master subtraction.
1. Use Number Lines
Number lines are great visual aids that teachers can use to teach subtraction. They provide a concrete representation of the concept, making it easier to understand. To teach subtraction using number lines, begin by drawing a line representing numbers 0 to 20. Then, ask the student to identify the starting number and subtract the given number from it by jumping backward on the number line. For instance, when subtracting 6 from 15, the student should jump six steps back from 15 and land at 9.
2. Use Manipulatives
Manipulatives, such as counting blocks or bears, are excellent tools for teaching subtraction to students. The students can hold the manipulatives and physically take away the required number to find the difference. For example, if the problem requires them to subtract two blocks from seven, they can remove two blocks and count the remaining blocks to get the answer.
3. Use Worksheets
Worksheets are excellent for helping students practice subtraction at home. Teachers can give students worksheets with subtraction problems up to twenty and let them solve the problems individually. It’s essential to give students different types of worksheets to keep them engaged and interested in the activity.
4. Use Online Games
Online games are an excellent way to teach subtraction to students. There are numerous math games available online that can help students learn subtraction. For instance, students can play subtraction games that involve popping balloons or racing cars. These games provide a fun and interactive way to learn subtraction.
5. Use Real-Life Examples
Teachers can use real-life examples to teach subtraction to students. For instance, when shopping, teachers can ask students to subtract the cost of one item from their budget and calculate the remaining amount. This helps students understand how subtraction is used in daily life.
In conclusion, teaching subtraction to students can be challenging, but using various methods and techniques can make it easier. Teachers should use different activities such as number lines, manipulatives, worksheets, online games, and real-life examples to help students master subtraction up to 20. As students progress, they will be better prepared to tackle more challenging subtraction problems, making their learning experience more enjoyable and successful.
