This resource is a remix of the original lesson from Illustrative mathematics https://tasks.illustrativemathematics.org/content-standards/3/MD/C/7/tasks/1990. Suggested Modifications- I like the original activity in the lesson plan on India's bathroom tile, however, it is crucial to allow students to explore and have a mathematical dialogue as part of the scaffolding process to activate their background knowledge on the content, instead of asking them to directly dive in the computation process. The modification will allow students to have a mathematical discourse about the topic, providing them an opportunity to work in an interactive learning environment with math manipulatives.
