A look at how problem solving
supports our understanding of mathematics
Presented by John Galbraith, Bev Marshman and Rob Gleeson
from the Centre for Education in Mathematics and Computing (CEMC) and all three with Thunder Bay connections.
John, Bev and Rob will share CEMC resources that aim to increase enjoyment, confidence and ability in mathematics. Through contests, face-to-face workshops, online resources, and publications, the CEMC provides curricular and enrichment support to elementary and secondary school students, teachers, and parents.
Breakout Sessions:
• Grade 4 – 6 Resources
• Grade 7 + Resources
• School, and Visits from the CEMC
(These sessions are dependent on numbers.)
Location: Hammarskjold High School Library
80 Clarkson St. South, Thunder Bay, ON P7B 4W8
Thursday, April 6, 2017
7:00 – 8:30 Presentation
All are welcome – no cost to listen and engage in discussion!
Pre-registration REQUIRED: maria_casasola@lakeheadschools.ca

Mathematics and Well-being: It’s Not About the Nail
Presented by Tom Boland
Tom has taught grades K – 8 and spent several years in Special Education. He is a published author, most recently publishing Leaps and Bounds Toward Mathematical Understanding, Grades 1/2, co-authored in 2015 and published by Nelson Education, and Mathematical Models for Teaching; Reasoning Without Memorization, co-authored with Dr. Ann Kajander and published in 2014 by Canadian Scholar’s Press.
It is Tom’s belief that ALL children deserve a safe and positive school experience, and that is the foundation of his most recent work. Together with colleagues Lori Carson and Dr. David Tranter, Tom is working to support teachers as they confront the ever increasing demands of simultaneously promoting well-being while doing all they can to support academic achievement.

]]>Making the Most of Children’s Mathematical Thinking: A look at how to recognize and understand children’s mathematical thinking
Presented by Dr. Alex Lawson
Author of What to Look For: Understanding and Developing Student Thinking in Early Numeracy
Math educator, Alex Lawson, Ph.D., is an Associate Professor of Education with Lakehead University’s Faculty of Education. A former elementary classroom teacher, she has been director of the Multi-Data Convergence Lab at Lakehead University for the last decade, where hundreds of hours of children’s thinking have been documented and analyzed to improve elementary mathematical instruction and learning.

]]>NWOAME Math Evening with Alex Lawson: “Making the Most of Children’s Mathematical Thinking” on March 2 starting at 6:30. More details to follow soon.
Regional Math Olympics on April 23 for grade 7 and 8 students. New this year: Grade 6′s will be invited to participate. More details will be posted soon!
]]>The first is an art activity about Tessellating a Circle
The second is a an activity with creating circle designs. Since the article also contains images, it has been included for you as a pdf: Circle Designs
Have fun!

Today’s activity uses Geometer’s Sketchpad to create pi. The link for the entire document with images can be found here: Pi Day Activity GSP. Enjoy!
A Recipe for Pi
Open up GSP4 and select new from the File Menu. Maximize the screen. | |
Use the Circle tool to create a circle. Click on the screen to create the circle. How far you drag determines the size – which can always be changed. | |
Use the select tool to choose the circle you just made on the screen. | |
Choose MEASURE from the grey toolbar at the top of the screen and then from the pull down menu select circumference. | |
GSP will automatically measure the circumference of the circle. Since this is dynamic software, as you change the size of the circle, it will automatically change the measurement. Test this out by using the SELECT TOOL to grab the point on the circumference and move it around so that its size changes. | |
Using the SELECT TOOL click on the CENTRE of the circle and the point on the CIRCUMFERENCE. The select arrow will turn sideways to let you know that you can select something. Then from the grey tool bar at the top of the page choose CONSTRUCT and from the drop down menu choose SEGMENT. | |
That segment represents the radius. To measure the radius, use the SELECT TOOL to choose the line segment. Then from the grey tool bar at the top of the page choose MEASURE and from the drop down menu choose LENGTH. | |
For this recipe for pi we need the diameter, the distance from edge to edge through the centre of the circle. To make the diameter, choose MEASURE for the grey toolbar at the top of the page and from the drop down toolbar, choose CALCULATE. This will activate the calculator. | |
To make the diameter, the radius needs to be doubled. Select the measurement of the radius by clicking on it and it will automatically go into the CALCULATOR. Don’t type in the measurement. To multiply by two choose *(this means multiplication) and 2 then click on OK. | |
Finally, choose MEASURE for the grey toolbar at the top of the page and from the drop down toolbar, choose CALCULATE. Use the calculator, and drag in the circumference of the circle, click on ÷ and click on the DIAMETER (radius x 2 that you just calculated) and then click on OK. | |
At this point you should have pi π (approximately 3.14). Pi is the ratio of the circumference of a circle divided by the diameter. It is a constant and doesn’t change. To prove this, click on the point on the edge of the circle and drag it to make it larger and smaller. All of the other measurements should change as you change the size of the circle, but pi will remain the same! |
This activity for the gym involves basketball shooting skills and the digits of pi.
Materials needed: 1 basketball per pair or group of students and a printout of the digits of pi (can be posted on wall behind basketball net).
Variation 1 (This works with a larger number of students since more can use one basketball net at a time.)
Variation 2 ( This works better with a small number of students.)
Link to pdf: Pi Day Activities Do or Die by the Digits of Pi
]]>To celebrate this special day, we will post classroom activities you could use on Friday to have some fun with your students too! At the bottom of each post will be a link to a pdf of the game or activity for you to use.
Today’s suggested activity:
Pi Day Activities: Duck, Duck, Goose, Shark
This is a variation of that favourite childhood game. The addition of the role of the shark allows students to recognize that three times the diameter of the circle is approximately equal to the circumference of the circle, since three is an approximation for p.
