Ep 132: The Ratio Table Model Pt 4

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 choiceRatio tables aren't a strategy, they're a model/representation of the strategy or strategies being usedIf you understand fractional equivalence, you don't need rules for fraction operationsHow to add 3/4 and 5/7 thinking and reasoning using a ratio tableDo non-equivalent ratios go on the same ratio table? How do you handle adding non-equivalent ratios?Note: for more information about the packs and sticks of gum scenario, listen to Episode 131See Ep 64 and 176 for more on equivalent ratios!Check out our social mediaTwitter: @PWHarrisInstagram: Pam Harris_mathFacebook: Pam Harris, author, mathematics education
