Rates and Proportional Reasoning: 2 tasks, Which is juicier? Comparing juice boxes’ ratios of juice concentrate to water and then Kayak, comparing kayakers speed and time given in fractional form. Both lessons were rushed and in hindsight, failures.
My students incorrectly set up juice fractions using part to part, not part to whole ratios. I should have pivoted back to a fractions refresher, looking at equivalent fractions and deepening my students’ understanding. Then moved into the kayak task.
