Document Summary

--mental computation: a strategies approach (the modules are available on the web. --most common form of computation used by adults in their daily lives. --it is needed as a check on calculator answers. --students should see it as the easiest way of doing many calculations. --it is an excellent way of learning how numbers work. --it is a creative and problem solving approach to numbers (mcintosh, 2004, p. 8) --the use of efficient counting strategies contributes to accurate number facts. --in developing basic number facts children should have the opportunities to experience, visualise, apply (learn how to apply), practise and ultimately to recall automatically. --the process/strategy children use is more important than the right or wrong answer. --encourage children to be risk takers- share their thinking on the whiteboard. The lecture referred to the sequence for teaching basic facts as follows: General strategies: count on 1, 2, 3, 0, tens facts, Doubles and near doubles, add ten, bridge 10, commutativity.
