- Question 1: Find what each picture equals using these equations: Frog plus 5 equals 13, Komodo Dragon plus Frog plus 8 equals 18.
Two pictures stand for two hidden numbers, and the child works out both. Numbers and results here stay within twenty. A picture keeps one value throughout, so a value found carries onward. Pictures on this sheet: Frog and Komodo Dragon.
Frog + 5 = 13, Komodo Dragon + Frog + 8 = 18.
Use one sheet as a quick check before a unit and a second afterwards to see what has shifted.
