Each jar contains 100 candies. Count in hundreds to find how many candies there are. Write the answer in digits.

In the first picture, we can see a jar of candies. And the first sentence tells us how many candies there are in it. Each jar contains 100 candies. Can you see how we write the number 100? It’s a one followed by two zeros. And we can see in the picture what 100 candies look like. Does this shape remind you of anything? Well, it might remind you of the 10 rows of 10 squares that we use to make a hundred square. And the place value block that we use to represent 100 looks like this too. Arranging the candies like this is a good way of helping us to remember that there are 100 in each jar.

Now we’re given a few jars of candies. We need to find out how many candies there are altogether by counting in hundreds. Now, imagine for a moment you were given all these jars of candies and somebody said to you, “right, I want to know how many candies there are altogether. Tip them all on the table and start counting, one, two, three, and so on.“ You’d have a huge pile of sweets and it will take you ages. Thankfully, our candies are arranged in groups or jars of 100. And this is going to make it much quicker for us to count.

Do you want to say each number as we point to the jar? 100, 200, 300, 400, 500. There are six jars of 100 candies, so we can count in hundreds six times to find out how many there are. There are 600 candies altogether. Now we’re told we need to write the answer in digits. Do you remember what we said at the start about writing 100 in digits? 100 is the digit 1 followed by two zeros. And we can see we’ve already got 100, 200, and 300 labeled already. 400 must be a four followed by two zeros. 500 is five, zero, zero. And so we know the number we want to write, which is 600, must be a six followed by two zeros. Six jars of 100 candies makes 600 candies altogether.
