Wave Project by Damien Kee

Hi everybody. Damien Kee had created some really cool projects with his "Wave" concept. I showed his videos to my students and asked them to create their own. This was a great project that really challenged the students to work together in a very coordinated fashion. Each class came up with their own concept. Per. 1 tried to end by having their robots drive in the shape of a #1 (somewhat successful), Per. 2 created a gauntlet for a robot to run through, and Per. 3 tried to end by having 5 separate circles with two robots driving around a third robot spinning in the opposite direction in each circle. You can see their results on my youtube playlist here: [|http://www.youtube.com/user/ianchowmiller#g/c/04BFE6CD07839962]

Hi Jason.

One pre-algebra idea, focusing around fractions and decimals. (I have not had opportunity to apply it in a classroom, but have done the program myself).

It's fairly straightforward to have the robot measure a distance, then move a chosen fraction of that distance. Requires use of sensors, data wires and math blocks, but pretty straightforward once you (or your students) get the basic idea. For example, you could set up a "wall" of 8 blocks extending from a classroom wall, and give the challenge to have the robot find and move through the gap between two selected blocks in the wall. If the gap is between the 2nd & 3rd blocks, they could: 1) measure the distance to the wall (using rotation sensor & touch sensors), 2) return to starting point, 3) multiply the measured distance by two and divide by eight, 4) move forward the resulting distance, 5) pivot 90 degrees to face gap in wall, and 6) Move forward to crash through designated "weak spot" in wall (perhaps have a small figurine or other marker standing on the wall straddling this gap?).

I believe this exercise will provide opportunity for students to gain a hands-on understanding of the meaning of the numerator (how many bricks I go forward) and the denominator (how many total bricks are in the wall). Once they've got a better feel for fractions, the exercise can be extended to decimals by requiring them to multiply the measured distance by the decimal equivalent of the fraction.

Another extensions would be to increase the efficiency and accuracy of the 'bot by measuring directly back from the wall (not retracing to starting point). That would require using a different fraction, and realizing and properly applying the difference would be a nice lesson.

Is this the type of thing you're looking for?
