ORDER OF MAGNITUDE
Order of Magnitude is designed to help children with counting and starting to assimilate the concepts of multiplication and area.
Many adults would probably need to study it for some time to work out what is special about the arrangements of squares.
It is one solution to the problem given below.

CONSERVATION OF AREA
The version shown was made in one piece with the stitches for each mitred square being picked up from existing squares.
The pattern includes instructions for:
diagonally-knit garter squares
straight garter squares
stocking stitch squares
Different types of squares require different methods of construction.
Use any yarn, in five colours, and needles of your choice.
The afghan shown was made using mitred squares. The pattern includes instructions for other types of squares.
The photo shows a small afghan, suitable for a child. It can easily be made bigger by increasing the size of the squares.

Use five rectangles to make a square. The rectangles must have sides of 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10, in any combination.
This afghan can help children to count and begin to understand the concepts of multiplication and area.
Each of the first ten counting numbers is shown on the side of one of the rectangles.
Go on to count the number of squares in each rectangle. Children will gradually assimilate that 7 rows of 4 and 4 rows of 7 both give the answer of 28.
Compare the number of squares inside the rectangles to introduce the ideas of ‘bigger than’, ‘longer than’, ‘shorter than’, etc. to introduce the idea of area. Many children think that a long skinny rectangle is ‘bigger’ than a short fat one, even when the area is much smaller.
This afghan is in the same pattern booklet as Place Order, which uses similar techniques.
