Thanks for inviting me to learn with you on your school based learning day! The group was energetic and excited to learn about meaningful manipulative use, spatial reasoning, concreteness fading and how they all fit with topics like fractions.
Here’s a summary of what we explored today:
The GECDSB Mathematics Strategy
The full GECDSB Mathematics Vision is here.
Warm-Up: How Do You See the Dots?
We did a quick Dot-Card warm-up asking you to visualize how you saw a series of dots on the screen. We went around the table and it seemed that everyone had a different perspective.
Here’s some of the ways you might have visualized the dots:
Tools and Representations
We discussed the importance of tools and representations to help students see mathematics from different perspectives. These quotes help us better understand some of the other important reasons tools and representations are so important:
K-12 Process Expectations: Representing
We very briefly discussed the 7 Process Expectations in mathematics that are embedded throughout our K-12 Mathematics Curriculum and looked in particular at the expectations for Representing:
Task: The Sandwich Problem
With manipulatives on the table (square tiles, relational rods, cubes, pattern blocks and fake money) we attempted to find concrete and/or visual representations that could help us solve and justify the following task:
We attempted to summarize the use of manipulatives on a continuum called “Concreteness Fading”. While the name suggests that concrete manipulatives fade away over time, it is important to remember that they fade away with one layer of abstraction and then reappear as a new layer is “piled” on.
Hope you folks found this professional learning experience useful. I’d be delighted to come back and learn alongside you all again sometime soon!
