ADDITIONAL INFORMATION:

J tried this on 27 December 2015 (6Y8M22D). He loved writing the fractions down. It took some time to explain this problem sum to him, but when I varied it to 2/4 + 2/4, he got a little confused. So I need to repeat this lesson at a later date.

0. Prepare your materials

1. Place 1/4 brick on the worksheet.

2. Place 3/4 brick on the worksheet.

3. Put them together on the left of the equation, saying "This is 1/4 + 3/4."

4. Place four 1/4 bricks, and say, "Which is equal to 4/4."

5. Place 1 whole brick and say, "4/4 is the same as 1 whole."
