## Big Math Ideas in K-2: professional learning series, fall 2019

Posted on: December 12th, 2019 by jnovakowski 1 Comment

For another year, we have held this three-part after school series with primary teachers to think together about the big math ideas in mathematics. For this series we focused on counting, number sense and place value understanding. Each teacher was provided with the teacher resource book Choral Counting and Counting Collections by Megan Franke, Elham Kazemi and Angela Turrou-Chan.

At our first session, we reviewed the different aspects of counting (see pedagogical content knowledge paper on counting available at the bottom of this post) and discussed ideas for both choral counting and counting collections. Teachers worked together in small groups to plan and lead a choral count that they would use with their students.

Stenhouse Publishers have an online choral counting tool you can use to plan out choral counts with your students. You can access it HERE.

Teachers were also asked to use the new SD38 Early Numeracy Assessment with some students in their classes and provide feedback on its usage and findings. This tool will be available publicly soon after this last round of trials and feedback.

At our second session, teachers shared what routines and innovations they tried with their classes and then we did counting collections together, considering ways to extend the counting collection experience by recording both the process of counting and the final count as well as recording equations that describe the count.

At our third session, we focused on place value concept development through tasks and games. Teachers had the opportunity to make some numeral materials. Its always handy to have sets of numerals available in the primary classroom for students to make connections between concrete rerpesentations of quantity with symbolic forms.

Some of the text slides from the sessions can be downloaded here:

Some other resources shared during the series are available here:

I have been fortunate to collaborate and co-teach with some of the teachers in this series as we continue to think together about developing number sense through counting and place value tasks.

Thank-you Janice,
I am envious of these stimulating, thought provoking and practical sessions that you provide for your teachers. I am also grateful that you share them with others. You are truly a visionary for mathematical thinking! Marsha
