Mason wants to know how many items
of fruit he bought. Answer the questions to help
him. He counts in 100s to find how many
cherries he has. Then, he counts in 10s to add the
watermelons. What three numbers should he say
after 310? 100, 200, 300, 310, what, what,
what.

In this question, we’re being asked
to count in 100s and 10s to help Mason find out how many pieces of fruit he has. The cherries come in boxes of
100. So he started to count his cherries
in 100s. 100, 200, 300. Mason also bought some watermelons,
which come in boxes of 10. So we need to start counting at 300
and keep on counting in 10s. 300, 310, 320, 330, 340. Now, we know that Mason had 340
pieces of fruit, the three numbers that he should say after 310 are 320, 330, and
340.

First, Mason counted his cherries
in 100s: 100, 200, 300. He counted his watermelons in 10s:
310, 320, 330, 340. So the missing numbers are 320,
330, and 340.

He also bought some oranges. Count on to figure out how many
pieces of fruit he has in total.

We know that Mason bought three
boxes of cherries. Each box contained 100
cherries. And he bought four boxes of melons,
and the melons came in boxes of 10. So we can start counting at
100. 100, 200, 300. We need to keep on counting in 10s
now because the watermelons came in boxes of 10. 310, 320, 330, 340. And we can count the oranges in
ones. The oranges are single pieces of
fruit. They haven’t been grouped together
in 10s or 100s. We count these as ones. 341, 342, 343, 344, 345, 346,
347. We counted in 100s, 10s, and
ones. The total number of pieces of fruit
that Mason bought is 347.
