Wednesdays is a special day at Lincoln school; we get out one period earlier. In fourth grade we also do a bunch of things we don't get to do on the regular days. One of these things is learning interesting math.
To cap off our math Wednesdays, I start with a fantastic math problem from Die Hard 3. The scenario: Figure out the math problem by the end of the math class or the bomb will explode! Students work in pairs and have two different sized cups (to represent a 5 gallon jug and a 3 gallon jug), a water bottle (representing the fountain), and a bucket to dump unused water in.
