Teaching High School Mathematics
I just created another linear Graphing activity to hopefully make graphing linear equations fun as we practice this over and over.
Today we did Barbie Bungee and it was great. Tomorrow I want to go back and make sure they can write the equation of a line through 2 points. After an activity on writing the equation of a line through two points at the beginning of class we are going to do this fun challenge.
Best part of this activity – Easy to understand the task:
Hit all the points with the least number of lines. (I might go back and write only this statement in the instructions. [I did!])
I’ve added the picture below of what I expect someone will try. Curious to see what else they’ll come up with. I’m going to make a Desmos activity(see below) to go with it so that they can check their own lines after they’ve completed the assignment.
I’ve really liked this option for the activities I’ve created recently. First I have them write their equations by hand to go through some points. Then they open desmos and the points are in the same place as the worksheet. Then they enter their equations. It becomes painfully obvious if their equations are incorrect and even in a low Algebra class almost everyone wants to fix them. Win. I don’t want them doing desmos to begin with because they can just keep changing values in the equation without much thinking.
A couple new thoughts for next time:
The same activity 3 times in 3 different ways:
