# 3.5: Silly Stickers

We know that one of these stickers costs .

Can you figure out how much it would cost for these stickers? In this concept, we will practice skip counting in order to figure out the price of sets of stickers.

### Guidance

In order to determine the price of a set of stickers like the one above, we can use the problem solving steps to help us focus.

- First,
**describe**what you know. - Second, identify what
**your job**is. In these problems, your job will be to figure out the price of the set of stickers. - Third, make a
**plan**. In these problems, your plan will be to count by the cost of one sticker in order to figure out the total cost. - Fourth,
**solve**. Do your plan. - Fifth,
**check**. In these problems, you can check your work by adding together the cost of each sticker.

#### Example A

Look at the picture below:

How much for these stickers?

**Solution:**

We can use the problem solving steps to help us figure out the price for the stickers.

#### Example B

Look at the picture below:

How much for these stickers?

**Solution:**

We can use the problem solving steps to help us figure out the price for the stickers.

#### Example C

Look at the picture below:

How much for these stickers?

**Solution:**

We can use the problem solving steps to help us figure out the price for the stickers.

#### Example D

Look at the picture below:

### Vocabulary

** Skip counting** is counting by a number other than 1. When you

**(2, 4, 6, 8) you are skip counting. In this concept we counted by 2s, 3s, 4s, 5s, 6s, and 10s.**
