I'm planning to teach the above unit but struggling with planning differentiated work. Chn will be soving addition money problems on day one. The LA understanding value of coins up to 20p using coins, MA- buying an item and making the correct amount using coins, HA- buying 2/3 items and adding the amounts together. Not sure whether to give coins to support them? Also instead of working out the total amount, would it be better if they solved word problems?
