Emma thinks that the number in Group C is greater than the number in Group D. Is this true or false?

Let’s start by looking at the number in Group C. How many tens does this number have? It just has one ten. So we can write a one in the tens column. How many ones does this number have? One, two, three, four, five. So we can write a five in the ones column. The number in Group C is the number 15. One ten and five ones makes 15.

Now, let’s look at the number in Group D. How many tens does this number have? There are two tens. Now, let’s count the ones. One, two, three, four, five. Both numbers have five ones. The number in Group D is the number 25. Two tens and five ones makes 25.

Emma thinks that the number in Group C, which is 15, is greater than the number in Group D, which is 25. Is she correct? Is 15 greater than 25? One ten is less than two tens, so the number 15 is less than 25. Emma’s statement is false. 15 isn’t greater than 25. It’s less than 25. The correct answer is “false.”
