      No Comments on The Variable – Volume 6, Issue 2

Volume 6, Issue 2 of The Variable, periodical of the Saskatchewan Mathematics Teachers’ Society, has just been released! From Kindergarten to Grade 12, there is something for everyone.

In this issue, Jeff Irvine shares a favourite lesson on domain and range (“Teaching Domain and Range of a Function Through a Constructivist Lens”, p. 4); Candace Joswick, Douglas H. Clements, Julie Sarama, Holland W. Banse, and Crystal A. Day-Hess explain how executive function demands may be increased or decreased in high-quality mathematical activities to meet their individual needs (“Double Impact: Mathematics and Executive Function,” p. 20); and Glen Aikenhead differentiates between in- and out-of-school mathematics, and encourages us to consider the positive implications of inviting Indigenous mathematizing into the classroom (“Out-of-School, Applied, In-School, and Indigenous Mathematics,”  p. 29). You will also find our regular features, including Shawn Godin‘s “Alternate Angles,” which takes an in-depth look at intriguing problems and their solutions (p. 15); “Intersections,” which will bring you up to date on upcoming professional development opportunities (p. 40); and “Tangents,” which highlights extracurricular opportunities for K-12 students interested in mathematics (p. 42).

Last but not least, this issue features the latest installment of “Math Ed Matters by MatthewMaddux,” a column by Egan Chernoff telling “slightly bent, untold, true stories of mathematics teaching and learning.” In this issue, Chernoff reflects on the ways in which different generations think about the teaching and learning of mathematics, and posits implications for the mathematics classroom of the future (p. 47).
