Today, pupils in P6 were exploring problems using a lot of their learned strategies with decimals. One problem in particular too a lot of thinking in terms of what was needed to be done. The scenario was:
A shopkeeper has 30 magazines. One the first day, he sells 8 for a price of £12.80.
On the second day, he sells 10 for £13.90.
On the third day, he sells the rest and gets £21.60.
On which day were the magazines the most expensive? How much did the magazines cost when they were the least expensive?
Through discovery, pupils identified the key facts: the total, the numbers sold for days 1 and 2 (and therefore for day 3), the total amounts in money for days 1, 2 and 3. That was the easy part. The hard part was what to do with all of the information.
I have attached a picture below of one pupil’s ideas as to what could be done to solve the problem.
This pupil chose to divide and compare, as you can see. The work showed a lot of thinking, comprehension and collaboration. Very well done!!!
