Welcome
Remember, one purpose of our sessions is to
network, so please sit with friends that you haven’t met yet!
Introduce yourself to the people around you;
explore a resource http://map.mathshell.org/ and/or www.wodb.ca and share one thing you found that was interesting from the websites with your table.

Task Discussion 3: Using Tools Effectively
July 16, 2016 9:45-11:15am
SLIDE 3
Standards for Mathematical Practice (p. 24)
1. Make sense of problems and persevere in solving
2. Reason abstractly and quantitatively
3. Construct viable arguments and critique the
reasoning of others
4. Model with mathematics
5. Use appropriate tools strategically
6. Attend to precision
7. Look for and use structure
8. Look for and express regularity in repeated
reasoning
SLIDE 4
Teaching Constructions
How do you introduce constructions in your teaching? Think Pair Share!
SLIDE 5
Idea!
SLIDE 6
Opening Tasks
Thinking as a student…
Use the tools in front of you to complete the following tasks: Task 1: Bisect the line segment Task 2: Bisect the angle Task 3: Construct a line to the given line through the point Task 4: Construct the center of the circle
How many different ways did you find to
complete each task?
Share with your tablemates.
SLIDE 7
MiraTM/GEOREFLECTORTM
Miras have been placed on your tables. Take
3-4 minutes to play around with one. See if you can use a Mira to complete any of the previous 4 tasks.
Who has used a Mira before?
How does one use a Mira?
SLIDE 8
MirasTM
With your tablemates, have you figured out all 4
constructions with the Mira?
How can a Mira be used with the “hat” worksheets
at your table?
SLIDE 9
Other Tasks
Using the tools in front of you, complete
the following tasks:
–Construct an equilateral triangle –Construct parallel lines (using a transversal) –Construct a line tangent to a circle.
Extension/Challenge: Can you use this tangent
to circumscribe a square?
SLIDE 10
Can you construct these?
SLIDE 11
Appropriate Tools
For each task, which tool did you find most
appropriate? Why?
Would you let students choose their tool?
How do these tools impact testing?
What about technology such as GeoGebra?
SLIDE 12
MiraTM Mini Golf
Try 1-3 with your tablemates.
What did you find?
Share!
SLIDE 13
MiraTM Mini Golf
Work on mini golf tasks 4 and 5 with your
tablemates.
Discuss and share!
SLIDE 14
MiraTM Mini Golf
On your table you will find copies of grid
paper.
As a table, create a mini golf hole. How many
banks will it take to get a hole-in-one?
Challenge another table to get a hole-in-one
with your creation.
SLIDE 15
Mini-Task Challenge
Given the construction, prove that AB is
perpendicular to CD.
Work with your tablemates!
What would your students do to solve the problem?
SLIDE 16
Geometry Wrap Up
What are your takeaways?
How can we use the teaching practices (p.22)
in our classroom?
How to reconcile (1) standards, (2) student
absences, (3) administrative support, (4) testing, (5) timing, etc. when implementing tasks?
