This past week I finally introduced my Algebra 2 students to the graphing calculator. We found zeros and vertices, and by Wednesday I had probably said "left bound, right bound" three million times. Seriously. Wednesday afternoon I made this poster to help everyone remember where to put the cursor to find the zeros of a quadratic.

Making free posters at work

It's hard to tell but this poster is made from 4 sheets of regular computer paper taped together and trimmed into a square. I made the poster by uploading the image to BlockPosters.com. The picture printed onto 4 sheets of paper. I could have chosen to make a bigger poster but my classroom is not huge. This size works well. If you think this poster will help your students, you can find the file called "left bound right bound" over there in the sidebar --->

Too much sitting!

By the end of the week, we needed a get-up-and-move activity so I made my students a scavenger hunt. Questions included: find the zeros, find the vertex and find the y-intercept. They all liked the y-intercept questions:) You can find this activity in the sidebar "freebies" section too. To get the practice we needed in this unit, we used this graphing calculator warm up template.

It helped my students gain confidence working with the graphing calculator to find zeros.
