Prepared posters for lesson demonstration

Lesson:

1) Demonsrate, using the posters you have prepared, how "Magic Squares" work. The total along any line, horizontal, vertical or diagonal is the same. (On the poster the "magic total number" is 34).

2) The second poster has numbers missing. Show how you can work out what they are. (First show that the total is 58, and then work it out from there.)

3) Give out the number squares (2 each) and let them work out the total number. The teacher should be wandering about the class asking individual students about the total number.

4) Give out the worksheet.

5) When they have finished, show then the "magic trick! (see below). Dont tell them how it works until you have done it about six times. Then tell only to those students to whom you are giving the "magic trick". Let them try it on their friends!
