9. Fractions

10. Partitioning…
Your friends come to a party with different lengths of long strips of gum. There is an argument over who has more.
Sara has 3/4 of a foot, 2/8
Tomas has 10/12 of a foot, 2/12
Jillian has 5/7 of a foot, 2/7
Miguel has 7/9 of a foot, 2/9
Draw a picture of each strip of gum and determine who has more.

What was challenging?

12. Partitioning… 3rd grade version
Your friends come to a party with different lengths of long strips of gum. There is an argument over who has more.
Sara has 1/6 of a foot
Tomas has 1/4 of a foot
Jillian has 1/3 of a foot
Draw a picture of each strip of gum and determine who has more.

13. Partitioning…
What reasoning do we expect students to use when they compare fractions with the same numerator and different denominators?

14. Cutting the Cake
Draw a rectangular cake. Now, cut the cake so that you and three friends get an equal section.
Can you cut the cake so all four pieces are equal but have different shaped-pieces?
Possibilities… 2 triangles and 2 rectangles
2 squares and 2 rectangles
2 triangles and 2 squares

15. Cutting the Cake What math concepts are you using and working with?
What is the big idea here that students are working with?

16. K-3…. What mathematical processes and concepts are involved with each of these?
2G2. Partition a rectangle into rows and columns of same-size squares and count to find the total number of them.

17. Remember… All fraction work in Grades 1 and 2…
Area model, no number line (tape diagram) models
Students in Grade 2 are not expected to write fractions as numerator/denominator. Instead, they use informal language.

18. Task Sort Solve each of the tasks.
For each task complete a row of the table.

19. Task Design Pick a Standard from the CCSSM
Write a few tasks that you can use with your students.
Characteristics of good tasks?
