I am getting more work from my students. Once they finish the comic strip, I have them save it and then either they e-mail it to me or I e-mail it to myself. Once I get it, I can grade it and print the comic strip off so I can show them to others. The comic strips are turning out quite well.
One of my students today asked if he could look up how fast a hummingbird beats its wings. In the process of finding that info, he discovered the following information about hummingbirds:
1. Their heart beats 1360 times per minute.
2. They can fly 27 mph
3. on average they beat their wings 70 times a sec but if they are mating, it could be up to 100 times a second.
4. Their tails make a whistling noise.
They requested some problems using this information for warm-ups on monday.
I stumbled across a bit on how some folks used two sides of a 29 story building to create a tetras game. I am trying to get enough information to create some warm-up problems. Today I showed my students a couple short clips on the event and they thought it was neat.

Real life math problems.
I was reading the news on yahoo.com yesterday and came across two articles I can use in my classroom to show some real live math problems.
The first involved a young lady who took a taxi cab from the station to the restaurant, a jaunt of about two miles. She used a credit card to pay for it and the taxi driver ran the transaction and added quite a tip so the total was close to $800. I can ask them how much was the actual taxi ride per mile and what percent was the tip the taxi driver gave himself. I can have them figure out cost per tenth of a mile. This opens up some nice discussion.
The other story was about a Chinese land developer in China who purchased a one year old full blooded Tibetan Mastiff for 1.9 million US dollars. He paid 12 million yen. This means I can have students figure out the exchange rate, $ per pound, percent above the normal price of a Tibetan Mastiff in the US.
Lots of possibilities and each one would make a great warm-up with the material and questions. I will have to keep an eye on the newspaper for various warm-up ideas like this.
