Today, I'm giving a pre-quiz before the review.  This is simply because I want a little bit more information about what to cover in my review.  I like to use SMART clickers to quiz students in class because it gives me immediate data from the class.  If you don't have access to this technology you can use a website like Poll Everywhere or simply give the quiz using pencil and paper.

On the day of any summative assessment, I like to take the time to wrap-up my instruction by using an animated interactive power point review.  The purpose of the review is to give the students one more look at the content this time at a global perspective so that students can make connections and solidify their understanding.  

In this review I want to focus students on some of the main ideas.

1) Geologic Timelines count backwards from the present day with the oldest dates on the bottom.

2) The scale on timelines is usually not accurate.  You have to look at the numbers to know the age of a period of time.

3) Timelines have different designs according to the author's purpose.

For me, there are two important instructional aspects of the power point.  First, I set it up to be interactive with several processing slides within the presentation so that students can hear thoughts from their peers as well as me.

Second, I use animation techniques in the powerpoint to capture student attention, include non-verbal visual cues, and allow for storytelling.  Making animated powerpoints can be time consuming and tricky, but I love it and find it well worth the time.  

Below are several screenshots of how to do different animations.  Once you have the skills, the rest is up to your imagination!

Closure depends greatly on timing and is not as easy to plan in advance as opening.  You can find more information about how I manage closure here.
