We can compare numbers and
sums. Which is greater, seven or six? Which is greater, two plus five or
four plus two?
We’re shown two models which
represent two sums. The total of the first sum is
seven. And the total of the second sum is
six. What did we add together to give us
a total of seven? Well, we have two orange bricks and
five pink bricks. Two plus five makes seven. If we start at two and count
forward five, that should take us to seven. Two plus one, two, three, four,
five. We landed on number seven.
What did we add together to give us
a total of six? Well, we have four green blocks and
two orange blocks. Four plus two is six. If we start at four and count
forward two more, five, six, we can see that seven is one more than six. So, seven is greater than six.
So, the answer to the first part of
the question, which is greater, seven or six, is seven. And we also know the answer to the
second part of the question. Which is greater, two plus five or
four plus two? We know that two plus five is
greater than four plus two because two plus five is seven and four plus two is
six. The answers are seven and two plus
