Unit 3: Reasoning and Explaining (MP2 and MP3)
CCSS Mathematical Practices: Reason abstractly and quantitatively
Pause here to compare the student responses to the Flower Arrangements task to the mathematical reasoning practice below. Look for evidence of the practice descriptors in the student work samples you just reviewed.
Reasoning Abstractly and Quantitatively:
- Make sense of quantities and their relationships in problem situations
- Decontextualize — to abstract a given situation and represent it symbolically
- Contextualize — to probe into the referents for the symbols involved
- Create a coherent representation of the problem at hand
- Consider the units involved
- Attend to the meaning of quantities, not just how to compute them
- Know and flexibly use different properties of operations
In your Metacognitive Journal, record evidence from the student work on Flower Arrangements that fit the above descriptors for reasoning abstractly and quantitatively.
