Find the missing number. Four plus one is five. Three plus two is what?
We know that four orange stars and
one green star is five. The second picture shows three
orange stars and two green stars. But we’re not told the total number
of stars. Let’s put all of the stars together
in a five frame. One, two, three orange stars and
two green stars. How many stars are there in
total?
Well, we don’t need to count them
because the five frame is full. Three plus two is five. The missing number is five. Four and one is five, and three and
two is five.
