Fill in the blank using greater
than, less than, or equal to. Matthew’s set is what Noah’s
set.
We’re shown two different models,
Noah’s model and Matthew’s model. Both models show an amount of tens
and ones. So we know that these are both
two-digit numbers. How many tens are there in Noah’s
model? One, two, three, four. Noah’s model has four tens. Now, let’s count how many ones his
number has. One, two. Noah’s number has four tens and two
ones. Four tens and two ones is 42. Noah’s number is 42.
Now, let’s look at Matthew’s
number. How many tens does it have? There are three. One, two, three. Let’s count the number of ones. There’s one, two, three, four,
five, six. Matthew’s number has three tens and
six ones.
Now that we know what both
two-digit numbers are, we can compare them. We need to compare the tens digit
because this digit has the greatest value. Noah’s number has four tens. Matthew’s has three. And we know that four is more than
three. So four tens, or 40, is worth more
than three tens, or 30.
Now, we can fill in the blank. We have to compare Matthew’s set to
Noah’s set. We know that three tens are less
than four tens. The number 36 is less than the
number 42. Matthew’s number is less than
Noah’s number.
