- Question 1: Find what each picture equals using these equations: Sea Horse minus Tuna plus 5 equals 12, Tuna plus Tuna equals 2.
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: Tuna and Sea Horse.
Sea Horse - Tuna + 5 = 12, Tuna + Tuna = 2.
Use one sheet as a quick check before a unit and a second afterwards to see what has shifted.
