Look at the group of children and answer the questions.
There are how many girls? Here’s one, two, three, four. There are four girls. There are how many boys? One, two, three. There are three boys. The total number of children is missing from the number bond. What is the missing number?
We know there are three boys and four girls. So how many children are there altogether? One, two, three, four, five, six, seven. The missing number is seven. What number is missing from this equation? Four plus the missing number equals seven.
We know that there are four girls and three boys and seven children altogether. So the missing number is three. There are four girls, there are three boys.
The total number of children is seven because four plus three is seven. The missing number was three.
