Scarlett is using base 10 blocks to
help her compare numbers. Which is bigger, eight or
three? Which is bigger, 18 or 13? Pick the correct symbol to compare
the numbers. 18 is less than 13, 18 is equal to
13, or 18 is greater than 13.

This question is all about
comparing numbers. First, we have to compare the
numbers eight and three and decide which is bigger. One way to compare the numbers
would be to look at the size of the group. We can see that eight squares is
more than three squares. The group with eight has more. The group with three has less. When we’re counting, the number
eight comes after the number three, three, four, five, six, seven, eight. We know when we’re counting
forwards, the numbers get bigger. Eight is bigger than three.

Now we have to compare the numbers
18 and 13. We can see the number 18 has been
broken apart into one ten and eight ones. 18 is 10 and eight ones. And the number 13 has been broken
apart into a 10 and three ones. We already know that eight is more
than three, so 10 and eight ones must be worth more than 10 and three ones. So the number which is bigger or
worth more is the number 18. The final part of this question
asks us to pick the correct symbol to compare the numbers 18 and 13.

This first symbol means less
than. 18 is not less than 13. It’s more than 13. We know this isn’t the correct
symbol, and this symbol means equal to. 18 is not equal to 13; it’s worth
more. So it must be this symbol, greater
than. The correct symbol to compare the
numbers is greater than because 18 is greater than 13.
