An introduction to multiplication using square turtles to demonstrate how a multiplication fact can be written in a number of different ways. Six turtles move around to show how six can be represented in different ways as a multiplication calculation. This process is then repeated for different numbers of turtles.
Beginning with six children, the pupils could arrange themselves into the same formations as the turtles, recording the relevant number sentences on the board. The same could be done with different numbers of pupils, arranging them into different formations and recording each multiplication. Once pupils have a good understanding of how different numbers can be multiplied together to obtain the same answer, they can then create their own factor spiders for different numbers.
