Reflection: Checks for Understanding Water Balloon Problem Solving Part I - Section 4: Student Practice

 

Looking over student's journals at the end of today's lesson helped inform my instruction for tomorrow. Here's what I learned! 

Here, a student gets Two Conflicting Answers using multiple strategies. I'll need to remind students to only move on when they achieve the same answer twice! 

This student did a great job showing her work, but Still had Some Left Over!. There's 4,000 milliliters in 4 liters and she only used up 3,600 milliliters. I think this is because she saw that 1 liter filled 3 balloons and 2 liters filled 6 balloons and reasoned that 4 liters must fill up 12 balloons. I appreciated that she is looking for and making use of structure (Math Practice 7), but I want to see her also attend to precision (Math Practice 6).

Here is an example of a student who Needs to Be more Careful. Similar to the previous student, he also got up to 12 balloons and thought he was done. In addition to this mistake, he wrote 3,600 milliliters instead of providing the number of balloons needed. I'll need to encourage students to reread the question when they have found a potential answer.
