Description

It's time to talk equivalent ratios and fractions! In this episode Pam and Kim demonstrate how understanding equivalent ratios leads to powerful reasoning about fraction operation, without the need to memorize steps and rules or algorithms.
Talking Points:

  • Empowerment is about having choice
  • Ratio tables aren't a strategy, they're a model/representation of the strategy or strategies being used
  • If you understand fractional equivalence, you don't need rules for fraction operations
  • How to add 3/4 and 5/7 thinking and reasoning using a ratio table
  • Do non-equivalent ratios go on the same ratio table? How do you handle adding non-equivalent ratios?
