Learning Objectives
Students will be able to round whole numbers to the nearest ten or hundred.
Introduction
(5 minutes)- Call students together.
- Give students the following scenario: They're at the store and need to buy something that costs $28, but they only have ten dollar bills. Ask them how many hundred dollar bills they would need to give the person at the cash register. (A student should be able to say they would need three ten dollar bills.)
- Congratulate students on the fact that they have just rounded the number 28 to the nearest ten (30). Explain that rounding a number is a way to make it more convenient for calculations.
- Ask students if they can think of any other times when they might need to round a number. (Almost any time you would need an estimate, it is appropriate to round.)
