Session 2 - Division of Fractions

Igniting Background Knowledge (5-10 minutes)

Activity: Ruler Warm-Up and Ruler Warm-Up Answer Key

Directions:

Before delving into the lesson let’s warm up the students' brains. 

• Give students the Warm-Up and have them read the directions. Encourage them to use actual rulers if they would like to use something tactile: Ruler Warm Up. You can ask them to work individually for a few minutes and then check with another student. 

• Check their answers using the Ruler Warm-Up Answer Key. 

• Why are we doing this? The ruler warm-up will allow students to physically divide fractions in a measurement setting. This will help them comprehend conceptually what it means to divide.  

• Focus: MP1: Making Sense of Math and Perseverance

Lesson Activity Model (20 minutes)

Activity: Discussion on solutions

Focus: *MP3: Construct Viable Arguments

Directions:

1. Take the sample student answers & questions from Step 2.
2. Hand them out to the students or have them viewable
3. If you are doing this with a whole class: Group students according to their solutions on the pre-screener and have them discuss their similarities and differences. 
4. If you are doing this with an individual or a small group, discuss the answers as a group. 
5. Then have them answer these questions as a group. (Visit the Resource Bank to learn more about “Grouping.”) 
6. If students get stuck understanding or explaining, here are some questions you can use to guide their thinking: Why did Chris divide the cups into fourths? What do the numbers in each circle represent? Why did he draw 5 circles? What do the numbers Jo is using represent?
