  • First we categorized the potential tasks from Friday by objective.
-Determine students’ prior knowledge
-poll to determine prior knowledge
-Write or share “what is a solution to an equation?”

- In pre-test "How do you know whether or not a point is on a graph?"
-Students will be able to solve a problem with 2 unknowns systematically
-simple problem (like chickens), reasoning problems (animals, hats/umbrellas, etc)

-come up with as many ways to solve the problem as you can (graph, table, equation)

-use a problem with rich context/hands on moving around (sprint/walking task)

-Represent a problem with one constraint in many ways and then combine constraints to make a system. (CPM, break even problems)

-Berlin Airlift problem

-income tax/countries problem
-Students will identify solutions and non-solutions to a system of equations using graphs, tables, and equations and be able to justify why a particular set of values is a solution.
-exit slip

-Nspire file “What is a solution?”

-population task (Wasatch and Summit county populations)

-Wartime Battle activity

Possible tasks:
- We like the idea of students working with separate constraints and then bringing them together to solve a situation
- Population scenario: involves estimating and writing equations, maybe we want something more intuitively accessible
- Scenario of winter sports problem: is this really more engaging?

  • Next, we created a potential lesson flow.

Proposed Flow:
- Pairs work with individual equations
- Discuss what is a solution?
- Bring together equations and look at solutions
- Do N-spire activity (reserve: depending on student responses)
- More practice/examples
- Exit slip to evaluate objectives (2 and 3)

  • Finally, we divided into three groups to work on different parts of the lesson.

1- Contextual Activity planning: Bushra, Tom, Pedro, Vicki

2- N-spire activity: Mary, Dave, Jocelyn, Brynja

3- Extra Practice Assessment/exit slip: Betul, Karen, Bill
