Yummy Math - real-life math activities


Yummy Math We provide teachers and students with mathematics relevant to our world today …

Yummy Math is actually a fantastic website. It has real-life math activities (as PDF and Doc files) that are free. The solutions, however, are only available to subscribers.

Recent topics include Starbucks, light bulbs, NFL,  the U.S. Open, Labor Day, hurricanes, earthquakes, cheesy goldfish, going back to school, the hot summer, cost of diapers, or even the rescue of Chilean miners, etc. etc.

You can find real-world math activities that relate to social studies, earth science, food, entertainment, sports, holidays etc. I really like this site. The activities are well-planned and so varied!

Perennial Math - math competition

Perennial Math is a new mathematics competition for students in grades 4-8. I thought some of you would be interested in it! What follows is their information that I have copied.

Your students can participate at either a team level or individual student level by registering on Don't worry if you cannot access the internet, you can always print and administer the tests to log in your students' scores later.

The competition consists of 5 tests each year (November-March). Each test contains 5 questions that get progressively harder. The tests must be completed in 30 minutes.

All students receive a certificate of participation and your team winner will receive a gold medal. Additional awards include plaques for teams who score in the top 10% and dog tags for each student who scores in the top 10% at each grade level. Students who get a perfect score on the test-and exceptional teams can have their name scrolling on our wall of fame.

Math in the real world

I've put together a page of web resources about math in the real world. These include a website with movies that show how algebra is used in real life, a site with multimedia explorations, information about careers that require mathematics, sites with activity worksheets with real-life data, and some articles. Enjoy!

Math Mammoth for school teachers

This is a special offer I'm extending to school teachers, all around the world!

This is your chance to get Math Mammoth downloadable books for free, in exchange for making a PRESENTATION.

Here's how this thing works:
Contact me and I will send you Math Mammoth materials on a certain topic, such as basic addition or division facts or fraction addition, etc. Nearly any topic in grades 1-7.

Document (photos and/or videos) your class using the materials, and write up a "report" or a presentation, showcasing what you did, how the students liked it, and so on. It could be of a single teaching session, or it could cover a longer period of time. You could include student responses & comments, an example lesson plan, etc. Be creative...

Send me your presentation.  I'll look it over. Depending on the quality and extent of your presentation, you'll then get MORE materials -- several books, or the whole Light Blue Series download, or the All Inclusive download.

Fun and practice with Roman Numerals

Someone asked me recently whether I include Roman Numerals in Math Mammoth. Yes, I do... they are in the 3rd grade materials, but the section is not extensive.

For some extra fun, learning, and practice with them, check out these web resources:
