Hi, can you offer some constructive advice? I have an interview next thurs, for 25 yr1/2s, mixed ability, but defo erring towards low y2. The lesson is to be a 20 min numeracy lesson. LO: Solve mathematical problems or puzzles; find totals; work out which coins to pay. On IWB present chn with several priced items, can we buy 2 items that cost less then 20p? Then in pairs (using coins/multilink) can they suggest other combinations? How much will that be altogether? For challenge/extension, can you buy 3 things for less than 20p?
