one thing to help consolidate is to do " word problems", practical problem solving and investigations. They make sure the concepts are firmly embedded and make further work easier..

for some reason this is a sticking point with a lot of children.

eg There are 234 children in school and there is a whole school outing. The secretary is booking coaches. How many 52 seater coaches will she need to book?

John has 12 blue pens and 14 red pens how many pens altogether?

Highlight the important bits in the question to find what you need to do. A stack of questions like this go well with the operation sorting activity suggested earlier especially if you discuss each question.

Google word problems year 3 and you will find all sorts of things. Online games also make the maths automatic as you don;t have time to ponder before the alien gets you.

Rather than go on to further content ask the children to explain why or how they got an answer, does this work with all numbers? Can they see a rule?

If you do combination type investigations eg how many different combinations can you make with 3 flavours of ice cream, what if you are only allowed a maximum of 2 scoops of each flavour? What if a 4th flavour is introduced? If vanilla is the cheapest for the ice cream shop to buy, what combinations give him the best profit etc. Sometimes children suggest variations eg with or without a chocolate flake..

convert ml to litres , kg to grams to work out the prices in supermarkets ( don't even attempt this after work when you and the children are tired and hungry!) which is better value - the price per unit is displayed but some are per kg, some per gram.
