Proportional Reasoning Using a Double Number Line

January 7, 2020 at 09:00:00 PM · Eastern Time (US & Canada)
About This Webinar

To think proportionally or not to think proportionally is that the question? Is everything relative? How can we scaffold proportional thinking beyond ratio tables or ‘cross multiply’ by using a double number line? In this session I will share my journey with moving students from multiplicative thinking to proportional reasoning.

Recommended Grade Level: 6-12
