**Over 150 slides of symmetry-teaching goodness, plus 5 pages of printable pdf sheets that students can cut out!**
This may be my favorite of all my "Teaching With Powerpoint" series. If your students don't understand symmetry after working through this, I'll gladly refund your money.
This activity is made to take place over at least 4 separate days. Notice that the printables say “Day 1,” “Day 2,” “Day 3,” and “Day 4” on them, so you would typically print only one sheet for students per day, and walk through those 4 shapes with them during that teaching session.
The way I have used it is to have each student cut the next shape on the PowerPoint as you talk through each slide together, doing only 4 shapes each day, then coming back to it again another day. Let students fold their cut-out shapes and look for symmetry. If you have a screen that students can reach, you might even encourage them to walk up and draw the lines of symmetry before the PowerPoint shows them the answers.
I included a sheet at the end on which they can record their answers, but when I do this with students, I usually have them draw lines of symmetry on their cut-out shapes, then write “2 lines of symmetry” or whatever the answer is on the actual shape. You might consider going through this process first, then letting them write on the last sheet at the end of the activity for that day.
Teaching With PowerPoint
The vision behind “Teaching With PowerPoint” is to use PowerPoints not just as a presentation tool, but to actually teach content. I have been a classroom teacher for over 11 years, and I think I’ve found some pretty clear, concise ways to communicate some tricky concepts such as telling time, money, and many others. I use my method of teaching and create PowerPoints which walk through skills in a step-by-step fashion.
My hope in doing this is to give new teachers some additional tools that you can use to effectively communicate concepts to your students, possibly even helping you pick up a few tricks along the way that you hadn’t considered. I also hope that seasoned teachers will find these useful, since it’s something you can easily put up on the screen and walk your students through. In most cases, you probably aren’t necessarily seeing anything you’ve never seen, but I’m taking the time to create these so that you don’t have to.
The way these PowerPoints are designed to be used is to put them up on a screen (hit F5 to start), then continuously click a wireless pointer or wireless mouse as you talk through them with your students. There is no audio on these since the sound of the teacher’s voice and class interactions are what should be heard during the lesson. I intentionally design my PowerPoints on a simple white background both to decrease distractions and to give you the ability to move slides back and forth between PowerPoints more easily if you want to do that. If you want a spiffy design, you can just click the “design” tab and click one that suits you. I find that the white background creates a little more of a “white board” feeling which keeps things simple. That’s how I like it, but you’re welcome to make changes once you have it. You can easily jump into any part of a PowerPoint by finding the slide where you want to start and hitting Shift-F5. This is a great way to use these as an ongoing teaching tool from day to day.
I hope you’ll find these useful to your teaching. If you see anything you think should be changed, or if you have ideas for other PowerPoints that I haven’t designed yet, please let me know. I am continuously in the process of making new ones.
The more you buy, the more I will be motivated to design, so thanks for all your support!
