1 Math Lesson 5.5 I can look at different shapes, tell what fraction they are divided into, and write the fraction as a number. Partition a whole into equal parts and define the equal parts to identify the unit fraction numerically.

2 Skip Count by 8s … Skip Count!
Starting when I say “GO,” skip count by 8s as high as you can in 90 seconds.

9 Problem of the Day Mrs. Lambrectsen’s class!
Mrs. Lambrectsen cuts a 6-meter rope into equal size pieces to make her class jump ropes. Mrs. Richardson cuts a 5-meter rope into three equal size pieces to make jump ropes for her class. Which class has longer jump ropes? Mrs. Lambrectsen’s class!

10 Concept Development 1 half Whisper the name of this shape. Circle
Watch as I partition the whole circle into equal parts. What is the name of each equal part? 1 half

11 Concept Development 1 half is the unit form. This is how we write it numerically (with numbers): ½. ½ is called the unit fraction.

12 ⅓ Let’s ANALYZE shapes 1 third
This shape is divided into equal parts. What is the name of each unit? 1 third Write the unit fraction for the shaded part on your white board and hold it up.

13 ½ Let’s ANALYZE shapes 1 half
This shape is divided into equal parts. What is the name of each unit? 1 half Write the unit fraction for the shaded part on your white board and hold it up.

14 9/10 Let’s ANALYZE shapes 1 tenth
This shape is divided into equal parts. What is the name of each unit? 1 tenth Write the unit fraction for the unshaded part on your white board and hold it up. 9/10

15 ⅚ Let’s ANALYZE shapes 1 sixth
This shape is divided into equal parts. What is the name of each unit? 1 sixth Write the unit fraction for the shaded part on your white board and hold it up.

16 ⅘ Let’s ANALYZE shapes 1 fifth
This shape is divided into equal parts. What is the name of each unit? 1 fifth Write the unit fraction for the shaded part on your white board and hold it up.

17 ⅕ Let’s ANALYZE shapes 1 fifth
This shape is divided into equal parts. What is the name of each unit? 1 fifth Write the unit fraction for the unshaded part on your white board and hold it up.

18 No! Let’s ANALYZE shapes No! Discuss with your partner:
Does this shape have equal parts? No! Turn and talk: If the parts are not equal, can we call them fourths? No!
