We began talking about the vocabulary gallery walk and the benefits of using this type of activity both before and after covering a certain topic.  We then moved into talking about the concept of skills that translate with the ideas of Larry’s son at college and some of the number games in the power point that relate to input/output, functions (processes), and inverse operations.  We discussed the idea that these games would play out differently in the different grades and had two very different representations on the board for the idea of the inverse operations problem – “get me where I started”.

Charles then began with the pool membership problem and once we agreed on the additional information we needed, we worked on finding a “break even” point.  We had a great discussion about the 40% off versus the 10% then 30% and the 30% and the 10%.  There were several methods of approaching this idea.

Marina had us work in pairs on explaining the thinking behind the students on page FA5.6 and being precise in our explanations.  We saw benefits in all the types of thinking.

We ended sharing the website mathmistakes.org which has some great examples of mistakes students make but also affords the opportunity for collaboration about students’ mistakes.  We watched a video about a student’s misconception of the number 18 and place value behind it although she understood the idea in a different context.  We then discussed the benefit of thinking through our thinking and the thinking of others and watched some videos of what that can look like.
