Teaching students to divide by 1-digit numbers is an essential skill that they will need to master in their math education. One way to teach this is by using the activity “Pick the Better Estimate.” This activity is designed to help students develop their estimation skills, which are essential for mastering division. Here’s how to implement the activity in your classroom.
Step 1: Explain the Concept
Before starting the activity, it’s essential to explain the concept of estimating. Estimating is a way to make an educated guess of what the answer might be based on the information given. It’s a helpful tool when working with larger numbers or calculations that are harder to do in your head. It’s important to note that estimating is not exact, but it helps to check if your answer is reasonable.
Step 2: Give Examples
After explaining the concept, give examples of how to estimate when dividing by 1-digit numbers. For example, when dividing 32 by 5, you could estimate that the answer is between 5 and 10. You would pick 6 as the better estimate because it’s closer to the actual answer of 6.4.
Step 3: Play “Pick the Better Estimate”
Now that students understand the concept of estimating, it’s time to play the game. To play, give students a set of division problems to complete. Then, ask them to pick which is the better estimate of the solution.
For example, if the problem is 76 ÷ 4, the better estimate might be 20. If the problem is 54 ÷ 8, the better estimate might be 7. Encourage students to explain their reasoning and discuss with their classmates why they think their estimate is better.
Step 4: Increase the Difficulty
As students become more familiar with estimating and dividing by 1-digit numbers, increase the difficulty of the problems. For example, you could ask them to estimate the answer to 245 ÷ 7 or 972 ÷ 6. This will challenge them and help them to think critically about the best way to estimate.
In conclusion, “Pick the Better Estimate” is a fun and engaging activity for teaching students to divide by 1-digit numbers. It helps them to develop their estimation skills and think critically about the best estimate. By using this activity, students will gain greater confidence in their math skills and be better prepared for more challenging math concepts in the future.
