Session 5 Journal Write about how you are preparing for the test over Chapter 8. If the test was today, how do you believe that you would do? On which types of problems do you really need to concentrate in order that you will do well on the test? Make sure that your first and last name is on your paper. Leave it on the corner of your table for me to read.

Carnival Fish Game... Remember the game at the fair where you try to toss a ball in a fish bowl and if so, you take home the fish? Same kind of concept. My "fish pond" is made from the lid of the copier paper box. I then taped down some plastic cups. Since I needed 3 different colors, I took overhead pens and went around the inside top part of the cup (red, black, and red). I filled the lid full of cups trying to not have any spaces. I just put tape on the bottom of the cups. I have a ping pong too. Students are in groups. I take turns asking groups for a problem. Everyone works the problem. Each group shows me 1 answer. 1 point for correct answer, extra points are gained by getting the ping pong in a cup. I have the lid of cups on a desk and another desk in front of that. The students stand behind a line that is about 2 or 3 feet away. I ask that they toss the ping pong so that it hits the first desk and bounce it in to the cups. If it bounces out, no points, if it gets stuck on top of all of the cups, no points.... The kids liked it.
