How many blocks do you need to add
so that the number of blocks on each side is equal?
Three plus the missing number
equals five. Here, we have three blocks. How many more should we add to make
five?
We added one more. Now there are four bricks. If we add another block, there will
be five. And both sides of the scale are
equal.
We have three blocks. We added two more to equal
five. The number of blocks we needed to
add was two.
