The past two days we have been reviewing our first unit on the foundations of functions.
I used these stations below. I found ideas in our textbook and online. Students worked in teams of five students to help one another complete each station in less than 10 minutes. The conversations were awesome. I loved hearing students help one another understand key concepts. I believe we are ready for our first test!
In no. 3 you have "Find a regression equation."
ReplyDeleteWould this be a linear regression equation or a quadratic regression equation ?
Since two minutes of thinking followed by 5 minutes of action would give the progression rule and the missing values up to 10 at least, it should be clear that this is not linear.
I wonder how many observed that the sequence is
1
1+2
1+2+3
1+2+3+4
and so on.
Also, what conclusions should be drawn from the estimate for 7 ?
Most students realized that it was quadratic. They all graphed the points first on their calculators to observe the shape of the graph. A few questioned if it could be exponential.
