I created my very first glog (I created a trial week-long Glogster account), and it’s about Standard of Mathematical Practice #3: Construct a viable argument and critique the reasoning of others. This SMP is my favorite because I believe it has the greatest impact on students’ learning across ALL subjects. When students have to discuss their reasoning, they all benefit. See what these students shared in their exit slips after a whole-class share of work on a low floor high ceiling problem from youcubed:

I love that they used words/phrases like: “get more ideas for later” and “yet.” This implies that not only were they engaged with the task, but they also benefitted from the discussion because it “gave me an idea.”

Students can share in a variety of ways:

• whole class after a week of working on the problem during Math Workshop
• small group work – this way a teacher can hear the math talk and encourage students to share with the whole class later
• fish bowl discussion – all students can benefit from reflecting on what went well and what could be better

How do you get students to share their reasoning or the critique reasoning of others?
