One thought on “Algebra quiz”

Used it this week. Took about 20 minutes of class time. I began by running through the setup in the Learning notes with the whole group and then set them off to do the quiz. I led them towards solve which I think was not such a good choice and so have edited the activity by putting the rearranged formula in the hint column. This was important to bring out the cascade of calculations which was something the students were impressed by, i.e just change the first line and the new total appears at the bottom of the screen.

There is some neat use of CAS functions in the second part of the Learning notes, The ans key and extracting a number from the result of a solve command. Nice to have for students with a strong interest.
