Through argumentation you get the generalizations from students to make their justifications.
Have students develop two or more ways to explain a solution which may include using materials (provided nearby the class...not given or suggested to the students to use)
Compare explanations and develop the norm of what makes that explanation acceptable. Reinforce what makes it mathematical.
15x3…..reinforce the story 15 what? 3 what?...remind students to label/record that to improve our explanation.
Have others ask questions….this is a from of mathematical reasoning
Reinforce the acceptability of multiple ways. Support them to make connections to other or previous problems.
Be sure to explicitly note student behaviour that supports mathematical practices.
Reminding kids to ask how to make sense of what they are doing for themselves and for sharing with others.
-Be mindful of student body language especially with those who are generally withdrawn from learning. They are often the ones playing with the materials but they are actually able to use them and explain their thinking.
-Choosing the “visual” solving group to report first often allows for deeper understanding when hearing from those who have a higher level response.
I want to be sure that my students are able to link back to and remember the context of the problem. It is about finding the solution to the story not solving a maths questions properly. I also want to focus on incorporating our norms into my classroom on a daily basis across subject areas.
REPEATING: Always ask a student who has been listening and is confident to speak. This is used to provide understanding across the room for a point that has been made by one group.
ENGAGING: with the reasoning of others
Instructional activities (Quick Images) can be used and adapted at many levels. Good for visual representations and equations (excellent for moving into multiplying).
Anticipate: what will I expect to see from my students?
Predict and record different ways students will solve a problem
First, have the group discuss. Present the pen once everyone has shared in the small group and are ready to begin working it out on paper.
Set Norms/Launch: Norms then Launch
Monitor: make note of who is doing what
Close listening and noticing
Questioning to make thinking visible and to allow students to refine or revise their thinking
Pressing students to consider all aspects of the task
Select: which 2 groups will share back
Sequence: what order will they present in?
Connect: Circulate back to the BIG idea
