but many groups said that the answer was obvious (and could explain why) so I changed the question to "Would you rather be given 119 g of Canadian dimes or 542 g of Canadian nickels?"
They worked in groups on the big whiteboards. Here are some of their solutions:
Next we went back to the quadratic scenarios from yesterday. We finished the first one and worked on the second one, but will need more time on Tuesday to finish up (tomorrow is a PD Day and Monday is Family Day). My students seem to be understanding where the axis of symmetry is and why it is helpful for finding additional points.
After we finish this we will do some more work with linear and quadratic data before having a quiz. Then we move on to similar triangles and trig.
