Make a lever to toss a piece onto the game.
Toss three times.
Add the last two numbers and multiply by the first
or
Multiply first by second and multiply first by third
and add the two products.
Example: 2(10+2) is 2 x 12
or 20 + 4
Both have the same answer. 24
The students did the game 10 times and added to see who got the highest
grand total.
I brought the SENIORS SOLUTIONS field set for the class to see.
They would be able to do the FLL 2012 challenges with their RCX.
Oops those dots are blood.
Better now.
