Clip 16/43: Standard 6: Attend to Precision Using Decimals Part 1C
Overview
Mathematically proficient students try to communicate precisely to others.
Erika Isomura’s students continue pair work on the problems, defending their thinking to each other. They make use of the sentence stems Erika gave them (e.g., “I think ____ because,” “This way is easier on our brains because______,” “What do you think?” “How did you feel about this problem?” “I knew it was this answer because I thought about the 0s”).
Erika engages pairs in explaining their thinking (e.g., “Show me in your answer,” “Do you think that will work every time?”). She reminds her students to note moments in their work that suggest that they might need to have a discussion about it. This clip also relates to standard 3 (construct viable arguments & critique the reasoning of others) and standard 7 (look for and make use of structure).
