1 MODULE 5 LESSON 2 Specify and partition a whole into equal parts, identifying and counting unit fractions by folding fraction strips.

2 SKIP COUNTING Let’s skip count by threes to 30. The first time we will do it using our voices. Then we will do it again, but writing it on our dry erase boards or notebooks. Thumbs up if you understand Now that we have our 3s facts to 30 written down. Let’s underline each multiple of 6. __

3 SKIP COUNTING Now let’s skip count forward and then backward by 6s.

4 multiplying by 3 and 6 Fill in the blanks:  2 x 3 = 6 2 x 6 = ____  3 x 3 = ____ 3 x 6 = ____  4 x 3 = ____ 4 x 6 = _____

5 PROBLEM OF THE DAY! Gavin needs to cut a piece of paper into 6 equal parts. Draw at least 3 pictures to show how Gavin can cut his paper so that all parts are equal.

6 CONCEPT DEVELOPMENT  Before we start make sure you have 1. 8 paper strips 2. Zip lock bag (to save your paper – we need this for future lessons) 3. pencil / crayon (color of your choice – JUST 1) THUMBS UP IF YOU HAVE ALL YOUR SUPPLIES

7 Pick up one fraction strip. Fold it in HALF on the SHORT LINE of symmetry. Thumbs up when you’re done. How many equal parts do you have to the make the WHOLE fraction strip. TWO What fraction of the whole is 1 part. 1 Half Draw a line to show where you folded your paper. Write the name of the fraction on each equal part. ½ (one half)

8 1. There are ____________ equal parts in all equal part is called ____________________. 1 half 2

9

10 1. There are ____________ equal parts in all equal part is called ____________________. 1 fourth 4

11

12 1. There are ____________ equal parts in all equal part is called ____________________. 1 eighth 8

13

14 1. There are ____________ equal parts in all equal part is called ____________________. 1 third 3

15

16 1. There are ____________ equal parts in all equal part is called ____________________. 1 sixth 6

17

18 1. There are ____________ equal parts in all equal part is called ____________________. 1 fifth 5

19

20 1. There are ____________ equal parts in all equal part is called ____________________. 1 tenth 10

21 Look at your set of fraction strips. Imagine they are pieces of delicious pasta. Raise the strip in the air that best shows how to cut 1 piece of pasta into equal parts with your fork.

22 Look at your fraction strips. Imagine they are lengths of ribbon. Raise the strip in the air that best shows how to divide the ribbon into 3 equal parts.

23 Look at your fraction strips. Imagine they are candy bars. Which best shows how to share your candy bar fairly with 1 person? Which shows how to share your half fairly with 3 people? Look at your fraction strips. Imagine they are candy bars. Which best shows how to share your candy bar fairly with 1 person? Which shows how to share your half fairly with 3 people?
