Materials you need:
Step 1 : Draw a 4 or 8 inch square with your felt-tip pen.
Step 2 : You need to draw a grid of smaller squares onto your current square .
So get your pencil out and draw a 1 inch grid in the 4 inch square (if you chose an 8 inch square then draw a 2 inch grid).
Step 3 : You now need to draw the lines that will mark out the edges of each tangram piece .
These should be drawn darker than your grid lines. With the felt-tip pen, draw your first line from the bottom left corner to the top right corner, effectively creating two large triangles.
Step 4 : Create another triangle in the top left corner. Start from halfway down your main piece on the left side and draw a diagonal line that meets the top of your square in the middle .
Step 5 : Draw a diagonal line from the bottom right corner of the grid through the centre of your first line and stop at your second line .
Step 6 : Your fourth line will join your first and second line together. Draw a diagonal line from the point where your second line intersected the top edge. Draw through one square to the point where it meets your first line. It should meet the line at the bottom right corner of the grid square .
You should be able to see that you have drawn four clearly defined triangles and one square .
Step 7 : Your last line should be drawn from the point where your second and third lines meet (also the middle of your second line). Draw the line downwards on your grid until it meets your first drawn line .
Now your tangram set is completed, you should see 5 clearly defined triangles, a square and a parallelogram.
Step 8 : Rub out your lightly marked grid.
