Self-testers are an excellent way for students to review which facts they can recall and which they cannot. It is important that students record the facts they do not know for future learning.
The following strategies can assist learning:

  •  Do you know another fact close to this one (the unknown)? For example, you don’t know 4 + 7, but you do know 4 + 4.  How could you get from (known fact) to find the answer to (unknown fact)?
  • Picture what the numbers look like in tens frames.  Can you make a full 10, with some over? Draw a picture of this in your book.

tens frames.

  • • What other new facts will you be able to work out from (unknown fact)? For example, 4 + 7 = 11, so 5 + 7 = 12, 4 + 8 = 12, 3 + 7 = 10, 4 + 6 = 10, and 11 – 4 = 7, 11 – 7 = 4, etc.
