SMART Notebook Lessons - Similar Polygons and Solving Systems of Equations Using Substitution

Image
I've made it a goal to get more involved with lesson development using SMART Notebook with ETHS teachers that have the interactive whiteboards in their classroom. Several faculty members have taken me up on my offer to help plan, design, and implement Notebook lessons for their curriculum, and I'll be sharing our products here, though you can find all of the links with descriptions on my website or on SMART Exchange.

In Similar Polygons, we wanted to reinforce ratios and setting up proportions from word problems. I used the drag/drop capability to encourage students to see where the numbers were coming from when creating a proportion. We then used some of the measuring tools to discuss what makes two figures similar. Finally, we used drag/drop to label geometric figures and coupled with setting up proportions in traditional problems.

For the lesson on Substitution, we had students drag values into variables, thus putting a hands-on approach to substitution. We gradually built…

Add the dynamic variable of Mother Nature into the mix and many headsets will be rendered useless when confronted with the elements. UClear has chosen to tackle this problem, and their military proven solution comes in the form of the HBC 130 Helmet Communicator. Read on past the jump to see how the device fared.
