FEATURES:

Color Scheme Highlights:
  • All even numbers have a warm tint because the pixel-size 2s are red.
    see detail
  • In contrast, all odd numbers have a cool tint.
    see detail
  • All numbers divisible by 5 and 10 have a distinctive tint because the pixel-size 5s are green.
    see detail

Pixel Patterns:

  • All of the prime numbers are solid colors and therefore distinct.
    see detail
  • Non-primes are filled with a pixel pattern of their color-coded prime factors, i.e. 6 i s filled with red 2s and blue 3s, as are 12, 18, 36, etc.
    see detail

Special Effects:

  • The exponential powers on the chart are distinctively shown (pixels are the same number and color, i.e. 25 is made up entirely of red 5s).
  • ‘Twin primes’ such as 17 and 19, or 41 and 43 are also easy to pick out.
This amazing variation on a ‘hundred chart’ highlights the characteristics of the numbers 0-100 and the factoral relationships among them. Challenge your students to decipher the meaning of the coded colors and patterns.

The effects of this multifaceted poster vary depending on viewing distance. From afar, the numbers appear as different color shades, including purples, blue-greens, and browns. Upon approaching the image, visual patterns of numerical relationships become discernible. At close range, the pixels inside each large-size number, which are prime factors of the large-size number, can be seen.

This poster is an excellent teaching tool, and discussion and lesson starter. It’s especially appropriate when used to supplement units addressing factors, multiples, primes, composites or exponential numbers. It is designed to stimulate discovery, investigation, and questions which can be responded to by teachers or students themselves.
