# Activities to Teach Students to Estimate Differences

Estimating differences is an essential skill that students need to develop to solve math problems. The ability to estimate the difference between two numbers is helpful in real-life situations such as shopping, budgeting, and cooking. For example, if a student wants to buy a new laptop, he/she needs to estimate the price difference between two models to make an informed decision. In this article, we will discuss some activities that teachers can use to teach students to estimate differences.

1. The “Guess and Check” Game

The “Guess and Check” game is a fun and interactive way to teach students to estimate differences. To play this game, the teacher needs to choose two numbers, say 25 and 17, and write them on the board. The students then need to estimate the difference between these two numbers without using a calculator or a pen and paper. After making their estimates, the teacher reveals the actual difference between the two numbers. The students can then check how close their estimate was to the correct answer.

2. The “Estimation Jar” Activity

The “Estimation Jar” activity is an excellent way to teach students to estimate numbers. To play this game, the teacher needs to fill a jar with different objects such as marbles, paperclips, or beans. The students then need to estimate the number of objects inside the jar without counting them. After everyone has made their estimates, the teacher reveals the actual number of objects inside the jar. The students can then compare their estimates with the correct answer and see how close they were.

3. The “True or False” Game

The “True or False” game is a game that challenges students to estimate if a statement is true or false. For example, the teacher could say, “The difference between 10 and 17 is greater than the difference between 100 and 93.” The students then need to estimate whether this statement is true or false. After everyone has made their estimates, the teacher reveals the correct answer, and the students can discuss their reasoning.

4. The “Estimation Race” Activity

The “Estimation Race” activity is a game that challenges students to estimate numbers in a fast-paced environment. To play this game, the teacher can display a series of numbers or problems on the board, and the students need to write their estimates on a piece of paper. The first student to finish estimating all the numbers correctly wins the game. This activity is a great way to encourage students to estimate quickly and accurately.

In conclusion, estimating differences is an important skill that students need to develop to solve math problems. The activities discussed in this article provide teachers with fun and engaging ways to teach students to estimate differences. By incorporating these activities into their lessons, teachers can help students develop their estimation skills and become better problem solvers.
