Fill in the blank. Seven take away what equals
We can use a bar model to help us
think about how to answer this question. We know there are seven to begin
with and we know there are two left at the end. We have to work out what we take
away from seven to leave us with two.
We can use a number line to help us
work out the answer. We know we have to start on number
seven and end on number two. How many spaces do we have to count
back from number seven to get to number two on the number line? One, two, three, four, five. So if we start at seven and count
back or take away five, we finish on number two.
Seven take away five equals
two. The missing number is five.
