Skip Counting by 100s to 1,000

Jenna is a famous outdoor photographer. Her latest assignment is to take photos at a leopard reserve in Africa. Let’s help her take some photos!

As Jenna looks around the reserve, she sees 10 planters of ferns. Each fern has 100 leaves. Before Jenna takes a photo of the ferns, can you help her find the total amount of leaves?

This sounds like an addition problem! 100+100+100+100+100+100+100+100+100+100. Wow! That’s a lot of 100s. Can you think of a more efficient way to find the total number of leaves? Great idea! Let’s try skip counting by 100. 100, 200, 300, 400, 500, 600, 700, 800, 900, 1,000.

There are 1,000 leaves.

When adding equal groups of numbers, skip counting is a great way to help make addition faster and easier. Let’s look at these numbers again. We can see that there are zeros in the one’s and ten’s place value. What do you notice about the hundred’s place value? That’s right! The hundred’s place value goes up by one each time we skip count! The number 1,000 almost fits in this pattern, but it has a zero in the hundred’s place and a one in the thousand’s place.

Jenna took a great photo of the ferns and is now focusing on the 10 water tanks she just found.

These tanks must hold water for the leopards! Each water tank holds 100 gallons of water. Before Jenna takes a photo, can you help her find the total amount of water in these tanks?

Each water tank holds the same amount of water, 100 gallons, so we can find the total amount by skip counting! Here we go! 100, 200, 300, 400, 500, 600. Uh oh. Can you help Jenna count the last few water tanks? Remember to use the pattern we learned about earlier! 700, 800, 900, 1,000.

There are 1,000 gallons of water! Great job! Now let’s see if Jenna can find those leopards. Hooray! Jenna found 10 leopards. Each of these leopards has 100 spots. Let’s help Jenna find the total amount of spots before she begins taking photos.

It looks like Jenna has already started skip counting by 100. Can you help her fill in the missing numbers? Let’s go! 100, 200, 300, 400, 500, 600, 700, 800, 900, 1,000.

There are 1,000 spots on these leopards.

Great job! Remember, skip counting by 100s is a great math strategy to use when adding equal groups of 100. Let’s practice skip counting one more time. 100, 200, 300, 400, 500, 600, 700, 800, 900, 1,000.

Thank you for helping Jenna take photos of the leopard reserve!
