- Question 1: Find what each picture equals using these equations: Letter minus 4 equals 0, Envelope plus 4 plus Letter equals 15.
Two pictures stand for two hidden numbers, and the child works out both. Numbers and results here stay within twenty. Equations add and subtract, so the child reads each sign. A picture keeps one value throughout, so a value found carries onward. Pictures on this sheet: Letter and Envelope.
Letter - 4 = 0, Envelope + 4 + Letter = 15.
Keep a small stack by the desk for children who finish other work ahead of the group.
