new student tutorial series on string graphs – ideal for year 10

This unit on string graphs is inspired by the amazing works by Architect, Engineer and Artist, Santiago Calatrava.

The four-part tutorial series will be conducted on Wednesday mornings from 11:00 to 11:30 am and presented by T-Cubed trainer, Roger Wander. Roger was a secondary mathematics teacher in Victoria, South Australia and the USA for over 30 years. His M.Ed studies at the University of Melbourne led to his move in 2008 to the Mathematics Education group at the Melbourne Graduate School of Education as a Senior Research Officer in the Texas Instruments-sponsored New Technologies for Teaching Mathematics project, which investigated the use of TI-Nspire CAS (Computer Algebra Systems) in middle secondary classrooms. He is currently a Clinical Specialist for the Master of Teaching graduate course at the MGSE, working with teacher candidates in secondary schools. He also works in the undergraduate subject School Experience as Breadth as the STEM stream lecturer.

Wednesday, July 22, 11:00 am Part 1: Gradients, Intercepts and Parameters

This first tutorial explores a family of linear graphs to produce a pattern similar to the one found on the Chords Bridge. Equations will be formed using information about the gradient and y-intercept. Each equation will be linked to form a family using something called a parameter.

Wednesday, July 29, 11:00 am Part 2: Points, lines and Parameters

This tutorial literally turns the first session on its side. Continuing the theme, more patterns will be formed linear functions. In this session we stitch lines to y = x and y = -x. Just like a time-lapse of the Milwaukee Art Museum, you can explore what happens when structures move. Equations will be formed using two points. Each equation will be linked to form a family.

Wednesday, Aug 5, 11:00 am Part 3: Working Simultaneously

In this tutorial we combine one and two to get three. The results from the first two tutorials will be used to further explore the patterns formed when these linear functions intersect. You will learn how to solve equations simultaneously, appreciate the use of exact values over decimal approximations and value the functionality of different mathematical representations.

Wednesday, Aug 12, 11:00 am Part 4: A table with a difference

This final session brings everything together. The patterns created and observed can be described mathematically. A simple tool called a ‘difference table’ will help identify the patterns. The curves can be described using simple expressions and graphed nicely using your TI-nspire CX CAS. You may even want to dive into further opportunities to extend your journey.
