This Lab is designed to be a hands on partnered exploration of how we divide fractions. This is very much B.A. BEFORE the algorithm :) This Lab will require exposure to simple bar models (drawing a whole rectangle and breaking it into four parts to demonstrate 1/4 of the whole).
You can either run the lesson as a demonstration and have students follow along, or call up students to model the practice problems. Or partner students with their own set of materials (there is a ton of value in this). When I originally taught this lesson I used salt, and it looked like we were cutting drugs.... so I've changed it for TpT to lemonade.
I begin by explaining how realistic this lesson is. That once in college I really wanted brownies.... at 2 AM. And I had everything to make the brownies, the mix, eggs and milk. But the recipe called for a half a cup of milk, but I only had a 1/4 measuring cup. I needed to figure out how many 1/4 cup scoops of milk I needed so that I would have the half cup of milk. Dare I not screw up the brownies! (My roommates would have killed me!)
Each student pair will need:
One cup with lemonade powder
A set of measuring spoons (ask them to bring in or borrow from your science department)
Two cups (label ahead of time Cup 1 and Cup 2)
1 piece of construction paper (this is so the lemonade won't go everywhere)
Lab - broken into parts where we practice dividing fractions by fractions, whole numbers by factions and whole numbers by mixed numbers. This is all hands on exploration so the kids will be dividing fractions before they realize that they're doing so!
Exit ticket - I introduce this before the lesson and let the students keep it on their desk. It allows the learners to see what they are expected to learn at the end of the lesson
Homework - Applies the concepts from the lab
Answer Key - My keys are (almost) always handwritten, I make the effort to scan them in as there is value to see how solutions are thought out
