The four times table is double, double!
You will need some regular graph paper, or the paper on the next page, which has larger squares.

• Fold the paper along any line that goes across the page. Then fold again on any line that goes up and down.
  
  
• Start at the point of the double fold. Colour in 1 square. Cut out the square, through all the layers. Open the first fold. Double 1 is 2. Colour the 1 square that has just been opened up. Open the second fold. Double again is 4. 4 × 1 = 4. Double 1, then double again. Colour the two 1’s that have been opened up.
  
  
• Back at the flat paper. Double the paper twice, as before. Start at the point of the double fold. Colour in 2 squares. Cut out the squares, through all the layers. Open the first fold. Double 2 is 4. Colour the 2 squares that have just been opened up. Open the second fold. Double again is 8. 4 × 2 = 8. Double 2, then double again. Colour the two 2’s that have been opened up.
  
  
• Back at the flat paper. Double the paper twice, as before. Start at the point of the double fold. Colour in 3 squares. Cut out the squares, through all the layers. Open the first fold. Double 3 is 6. Colour the 3 that have just been opened up. Open the second fold. Double again is 12. 4 × 3 = 12. Double 3, then double again. Colour the two 3’s that have been opened up. And so on.
  
  
• Make a display of the cut-outs, each one marked with its number sentence.

It doesn’t matter what shape the initial coloured block is, so long as at least 1 square is on both fold lines:
