Clip 23/29: Standard 1: Making Sense and Perseverance Using Rate of Change Part 2D
Mathematically proficient students check their answers to problems using a different method, and they continually ask themselves, "Does this make sense?"
Antoinette Villarin reminds her student pairs that — once they are confident about a match between graphs — they should record their matches and explain their justification, ensuring that both partners in each student pair understand and can explain their reasoning.
Student pairs discuss and record their thinking on their recording sheets. Antoinette circulates among the pairs and engages them in explaining their thinking — for example, reminding them to identify the starting situation to help guide them.
This clip also relates to standard 6 (attend to precision).
