Making the Most of Online Math Explorations by Wendy Petti

What is a math jewel? I can explore and “learn by doing” in open- ended ways. I am in control. I’m having fun without games. I would enjoy this activity even if I were older or younger.. It’s a math jewel if... ~ a multi-faceted resource with sparkling qualities ~

I can explore this activity better on the computer than off. I can read and understand the text. I can be creative. I see real-world connections. I can share ideas or data with classmates or students in other places. I understand..

 ~ some sad sites ~  Google’s top ten math sitesmath Flaws: Pages may contain distracting ads. math.com math.com Text may be dense, unclear, or misleading. AAAMath.com – place value, subtracting money, circumferenceAAAMath.complace value subtracting moneycircumference.

Activities may be harder to use online than off. Java pattern blocks Games may be worksheets or flashcards with gimmicks. Funbrain’s math baseball.

 ~ sad hidden messages ~  Math is mostly about finding right answers. Math is not fun, so it needs to be sugarcoated. Math is an isolated activity..

2 or 3 questions that are: probing and open-ended, providing some direction and some flexibility Ask questions before, during, or after the website visit. Responses may be written, discussed in small groups, or discussed as a class.. getting the most out of math jewels ~ ask useful questions ~

What strategies did you use to make your estimates? Did you find it easier to estimate crowds of a certain size range? If so, what range? Why was it easier to estimate crowds of this size?. sample questions ~ after exploring “What a Crowd” ~

–understanding –comfort and competence –curiosity and passion –ability to analyze, synthesize, apply –regular real-life connections –lifelong learning –empowerment Making Meaning ~ in English / language arts ~ What do we hope for our students?

Why do we immerse our students in a world of good books but don’t immerse our students in Mathland? As our students learn math… can we help them live math?. ? ? ? ~ If we have the same goals ~ and the same hopes…

Learn by doing ~ Use what we learn to make something we really want. Technology is a building material. Learning by doing is hard fun. Learn to learn. Take charge of your own learning. Take enough time to do the job.. 8 Big Ideas Behind Constructionism

You can’t get it right without getting it wrong (at first). Look carefully at what went wrong. Push against the resistance of reality. Do unto ourselves what we do to our students. Be active learners. It’s the digital age ~ use technology now. (Thanks to Seymour Papert for these big ideas!) 8 Big Ideas Behind Constructionism

With one computer and a projector: –a whole class can explore cooperatively –a teacher can demonstrate before students explore independently With 5 + computers: –everyone can explore in groups With 2 or 3 computers and 2 to 3 students sharing each computer: –everyone can explore in rotations over 2 or 3 class periods.. organizing the classroom ~ for productive computer activities ~
