Subtraction of decimal numbers can be a little tricky for students, but with the help of manipulatives, they can easily grasp the concept of subtracting decimals. Using blocks or base ten blocks is a great way to teach students how to subtract decimal numbers.
Here are some important activities to teach students how to subtract decimal numbers using blocks:
1. Show and Tell with Blocks: At first, it is important to introduce the blocks or base ten blocks to the students. You can start with a demonstration by using a few blocks and subtracting the numbers. Ask the students to participate in the demonstration by coming to the board and taking away blocks.
2. Practice subtraction with Blocks: After demonstrating, it is important to give students the opportunity to try it themselves. Distribute blocks to each student and ask them to create their own numbers using blocks. Once they have created their numbers, they can subtract them by taking away blocks.
3. Balancing Blocks: This activity will allow students to practice subtraction by balancing blocks. Give students a set of blocks and ask them to balance the blocks on a beam scale. After they have balanced the blocks, ask them to subtract one set of blocks from another set of blocks.
4. Roll and Subtract: In this activity, students will roll a dice with decimal numbers and subtract them using blocks. Provide students with a dice with decimal numbers from 0.1 to 0.9. Ask them to roll the dice twice and subtract the numbers using blocks.
5. Adding and Subtracting decimals with Blocks: This baking activity will showcase the use of adding and subtracting decimals. Provide students with baking ingredients with decimals (e.g. 0.25 cups of flour, 0.5 cups of sugar, etc.) and ask them to add or subtract the ingredients using blocks. Once they have added or subtracted the ingredients, they can create a recipe.
With these activities, students will have a better understanding of subtraction with decimals. Using manipulatives like blocks, is an effective way to teach math concepts and makes learning enjoyable for students.
