January Sales in Maths. Sêl Ionawr yn y wersi Mathemateg
This week in Maths, we have been continuing our work on percentages. We have been discussing how during the January sales, many goods are reduced in price and customers are tempted by 'too good to be true' bargains - 50% off! Reduced by 15%! 25% discount! Working in groups, we have set up our own shops where we used 'Post Its' to mark items with their original price and the percentage by which we are reducing the price (e.g 35% off) in our very own January sale!

We had to calculate percentage discounts.
Each group then visited the other shops in the class. We had to look at the items for sale and work together to calculate the percentage discount. We then had to subtract this from the original price of each item to find their sale prices. After shave with an original price of £48 and reduced by 15% (£7.20) for example, would cost £40.80 in our January sale.
Dyma ni yn trafod y prisiau. Discussing prices
We enjoyed working out how much the different items would cost in our sale. Later we returned to our own shop and we all compared our findings. Had we all calculated the same sale prices? We also discussed 'how' we had worked out our sale prices. It was interesting to compare our mathematics strategies. Many of us had arrived at the same sale prices but had worked out the answers in different ways.
