I'm linking up with those cuties, Amanda and Stacia, to share a book and idea I use with Number Sense!
An attempt to help children conceptualize the immensity of numbers is aided immeasurably by the artist's jovial, detailed, whimsical illustrations. Marvelosissimo the Mathematical Magician demonstrates the meaning of a million by showing his four young friends (plus two cats, a dog, and a unicorn) that it would take twenty-three days to even count to a million and that a goldfish bowl large enough to hold a million goldfish could hold a whale. Seven pages are printed with tiny white stars on a grid pattern against a blue sky -- adding up to only one hundred thousand stars! And after that, a billion and a trillion are discussed, all with equally or even more outstanding examples; a trillion children standing on each other's shoulders would almost reach to the rings of Saturn. The author concludes with several pages of the mathematical calculations which support his examples, very clearly and humorously explained. An unusual idea, smoothly and amusingly presented.
If you'd like to give your students this quick formative assessment, you can grab the freebie here! In the directions I say to give them 10-15 minutes. We only had about 5 minutes left to do it Friday because we're still getting used to our schedule. :-P It's really up to you, though, honestly! It's very open-ended, and just a way for you to observe their thinking. :o)
