Modelling in a Parallel Universe
Learning Goals• Practice posing parallel and open questions• Refine understanding of how different
representations of relationships highlight different characteristics or behaviours and can serve different purposes.
• Highlight the importance of being conscious and explicit about instructional decisions; specifically, the exploration of different models
Notes from the Exit Cards• Common threads in student struggles for our
group– Algebraic manipulation (factoring, completing the
square, expanding, etc…)– Connecting the concrete to abstract concepts– Understanding graphs– Connecting representations– Making connections in general
Notes from the Exit Cards• Common threads in our own struggles
– How do we find time to create all this ‘stuff’– How do we find time to deliver all this ‘stuff’– How to modify favourite activities to incorporate high
yield strategies– Connecting abstract and concrete ideas
• How do we use algebra tiles effectively in the classroom
– The meaning/differences between the big ideas and writing lesson goals
• How do we get to the skills too?
Minds On – Parallel TasksDetermine the equation of a function with the following properties:
Option 1 Option 2• Quadratic• Passes through
(–1, 5) • Has zeros 4 and 5
• Quadratic• Passes through
(–1, 5)• Has zeros and 65
65
Follow-up Questions
• Did you draw a graph?
• Did you use algebra?
• Which did you do first? Why?
Follow-up Questions
• Could you have predicted whether the ‘a’ value was positive or negative before you actually calculated it?
Follow-up Questions
• Is the value of ‘a’ what you expected?
• Explain.
Follow-up Questions
• Did you need all three pieces of information?
• Why? Or Why not?
Follow-up Questions
• How did you determine the equation?
Follow-up Questions
• How would the function change if the given point (-1, 5) changed to (-1, -5)?

Minds On – Parallel Tasks con’t
• Select one of the parallel tasks
• Form a group with others working on the same task
• Complete the task by selecting one of the questions and then prompt each other using the follow-up questions provided
• Match the parallel task to a big idea and then find all the expectations that are addressed by the two parallel tasks
Minds On – Parallel Task 4 U 2 do• Identify one struggle that you believe your
students have when studying quadratics and the corresponding expectations
• Find a like-minded partner
• Develop one parallel task as well as the follow-up questions
Action – Algebra Tiles
