Ss played a game that directly used these relational rods. They now need to score the total value of the rods. For reference, dark green on top=6. How would you calculate the sum? How do you think Ss would?

Using the levelling strategy, Neal says the mean of this data is 5.2. Nat says that the mean of this data set is 5.4. Who has a misconception? What would you ask?

How many? How do you know? Has your thinking changed from image 2? How might we use images like these to talk about inequalities? #unitchat #msmathchat #iteachmath

My friend Pam Harris posted over on another platform this prompt. What are your thoughts and how do you see my solution sparking conversation?

How are these two representations the same? How are they different?

When would you choose to use each representation to communicate an idea and why?

I just used the “levelling strategy” to find the mean of this data set. I know it’s kind of 4, but what does that extra cube at the top represent? What misconceptions might your students encounter with this model & how would you support thinking

What q’s would you ask your students about this representation?

How would you help them think
Additively?
Proportionally?
Part to part?
Part to whole?

What might this represent?
