Subtraction is one of the most important mathematical concepts that students learn in the early years of their education. It is the process of taking away one number from another to get the difference. Subtracting by 5 is a common skill that students need to learn as they progress through primary school. Here are some activities that teachers can use to teach students about subtracting by 5.
1. Number Lines
Number lines are a fantastic tool for teaching subtraction. Draw a number line on the board, or provide individual copies for students. Start at an even number, such as 20, and show students how to count backward in fives until they reach zero. You can also play a game where students take turns coming up to the board or standing in front of the class and subtracting by 5 from any number you call.
2. Flash Cards
Flashcards are a tried-and-true method for helping students learn subtraction. Make flashcards with subtraction problems, and have the students work on them in small groups or individually. Start with easy problems and gradually increase the difficulty as students become more comfortable with the concept.
3. Subtraction Bingo
Create Bingo cards with subtraction problems, and have students solve them by subtracting 5 from the given number. Students can use markers to cover the square containing the answer. Once a student has completed a row, they shout “Bingo!” and win a prize. This game is a fun way to reinforce the subtracting-by-five concept.
4. Picture Subtraction
Provide a picture of a group of objects and ask students to subtract five from the total number. For example, use a picture that has ten apples, ask students to cross out five apples, and then write down how many apples are left. Students can use a similar method with other pictures or objects. This activity helps students visualize the concept of subtraction in a practical way.
5. Songs and Rhymes
Songs and rhymes can be an effective tool for helping young students learn and remember math concepts. Create a song or rhyme with a subtraction-by-five theme to help students develop an understanding of the concept. You can also use existing songs or rhymes with subtraction themes such as “Five Little Monkeys Jumping on the Bed” or “Ten Fat Sausages.”
Subtracting by five is an essential skill that students need as they progress through primary school. These five activities are fun and effective ways for teachers to reinforce the concept of subtracting by five in the classroom. With these resources, students will feel confident and comfortable with subtracting by five in no time.
