When absent from your classroom for a while make your return lesson easy and or enjoyable. Whether gone for business, sickness, or a school holiday, give yourself a nice day.
My return lesson from this past weekends's conference is the "Cyber Cannon Lab". Shooting cannonballs at a target, reviewing some terms and leading a few new ones like: Ballistic and parabola, and more practice making graphs.
I planned three weeks ahead for this and got the library computers reserved. I did not have to worry about my lesson as a weary returning traveler.
See my school website for the lab and powerpoint notes.
Hope this helps,
Love to Teach and Teach with Passion
