Discussion points for teachers

1. Help Fabio work out how many boxes he will need to open in order to restock all the pencils by rounding to the nearest 100. Discuss how to round a 3-digit number to the nearest 100 by looking at the digit in the tens column.
2. The shop sells approximately 95 keyrings each day, how many boxes should he order to ensure that he has enough for five days? Discuss the best method for working out how many Fabio needs (for example, rounding to the nearest 100 first and then multiplying by 5, etc.)
3. He knows that the number was 600 when rounded to the nearest 100. How many magnets could have been sold? Discuss how to round up or round down to a given 3-digit number.
4. If 413 souvenirs have been sold so far, what number will Fabio record on the report if he rounds this amount to the nearest 10 or 100? Discuss how rounding to the nearest 10 and nearest 100 are similar and different.
5. . If 552 souvenirs have been sold this afternoon, Fabio thinks that the total number of souvenirs on his report will be 900 when rounded to the nearest 100 and nearest 10. Is he correct? Discuss whether numbers with 5 and 50 in round up or down and explore the differences when rounded to the nearest 10 or 100. Discuss whether to round the numbers separately, or add them up and then round. What is the difference between the two methods?

Optional discussion points:

Is rounding a good method to use when stocking a gift shop? Why/why not?
