Count the marbles.
In this question, we’re shown some
different jars of marbles, these two jars of marbles both contain 100 marbles. These three jars each contain 10
marbles. These marbles haven’t been
grouped. We count these as ones. So to count the marbles, we need to
count in 100s, 10s, and ones. Let’s start counting in 100s. 100, 200. We counted in 100s twice because
there are two jars of marbles and each jar contains 100 marbles.
Next, we need to count forward in
10s because we’ve got three jars of marbles each containing 10 marbles. We’re going to start at 200 and
count forward in 10s three times. 210, 220, 230. Now what we need to do is count
forward in ones. 231, 232. We counted the marbles in 100s,
10s, and ones. There were 232 marbles.
