- Question 1: Find what each picture equals using these equations: Cookie minus Muffin minus Muffin equals 0, Cookie plus 7 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: Muffin and Cookie.
Cookie - Muffin - Muffin = 0, Cookie + 7 = 15.
Leave it for a supply teacher, since the instruction is short and no equipment is needed.
