- Question 1: Find what each picture equals using these equations: Duckling plus Duckling plus 5 equals 13, Duckling minus Candy 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: Candy and Duckling.
Duckling + Duckling + 5 = 13, Duckling - Candy = 2.
Use one sheet as a quick check before a unit and a second afterwards to see what has shifted.
