Counting animals!

You are invited by a farmer to count the number of animals on the farm. Explore the following images. What do you notice? What is the fastest way you can count?

Share your thinking!

What did you notice about the number of animals in each group? Did that change the way you counted?

Picture # 1 How did you count the ducks?

Picture # 2 How did you count the dogs?

Picture # 3 How did you count the fish?

When we skip count we add the same number to the previous number. For example when counting the ducks there were groups of 2, so we skip counted by 2. Start at 2 and adding 2 more for each group of ducks. 2, 4, 6

Which number did you use to skip count the dogs? Which number did you use to skip count the fish?

Action

Skip counting!

The farmer needs more help from you!

The barn is full of hens. The farmer said there are 46 feet in the barn. How many hens could there be?

If each hen has 2 feet how can you count the number of hens in the barn? Try skip counting by 2s. How many hens did you count in the barn?

Press ‘Answer’ to reveal the solution.

The answer is 23 hens.
Three rows of hens. The first row has eight hens, the second row has seven hens, and the third row has eight hens.

Try this question!

We skip counted the hens by 2s because they have 2 feet. How would we count the sheep? Sheep have 4 feet.

How many feet would there be if 23 hens and 5 sheep were standing in the field together?

Press ‘Answer’ to reveal the solution.

The answer is 66 feet.

There are also some sheep and hens in the field of the farm. Altogether there are 8 heads and 22 feet. How many hens and sheep are there?
