Do you have an Nspire?

Bring your calculator & check in with Art, John/Judi or Cal– Is your system up-to-date?– Do you have the files we want

to use?

Day 12

Pushing all your buttons

Elimination Questions

This was obviously a challenging task… great work!

Themes that emerged:• Questions which varied an existing situation and asked

students to consider the impact.• Questions framed around the ideas of compare and contrast.• Questions which required interpretation of a problem or

solution.• Questions which required making a connection between and

among ideas.• Questions which probed possible misconceptions.

Things to work on…

• Some lines of questioning stopped short of asking for explanation; never got to "why?"

• Some choices of both vernacular and mathematical language and vocabulary were ambiguous: we need to model clear, correct and precise use of vocabulary for students.

ut simply, the only point of asking questions is to raise issues about which a teacher needs information (probe) or about which the students need to think (push).

Working inside another Black Box

Congrats! You just received a grant giving each of your students their own TI Nspire CAS.

Unfortunately, your grant requires you to use it in your systems of equation unit – and document your work.

Inside YOUR Black Box

• Three groups of applets have been pre-loaded that are specifically designed for use with a unit on systems of equations

Get comfy…

• Follow the instructions on the handout and get used to the applications (and the Nspire)– How might you use these tools to deepen

students’ understanding ?– How might you use these tools to gauge students’

understanding?

Schedule

• 11:15 – What is a Solution• 11:30 – The Elimination Method• 11:45 – Balanced System

Focus on how these tools would push and probe

Thanks for returning your Nspire!
