Fibonacci Day LEGO Garden

November 20, 2014

Did you know that November 23 is a Fibonacci Day? Why? Because 11-23* (1, 1, 2, 3) are the first numbers in the famous Fibonacci sequence. Fibonacci sequence starts with 0 and 1, and then every next number is the sum of two previous numbers (0, 1, 1, 2, 3, 5, 8, 13…). Interestingly, Fibonacci didn’t invent this sequence, but he introduced it to medieval Europe in 1202 in his book Liber Abaci. More importantly, he introduced Arabic numerals, the numbers we use today, in the same book. We celebrated Fibonacci Day by making a Fibonacci LEGO Build together.

Deciding on our Fibonacci LEGO Build

This idea came to me as my daughter said that she wanted to build a garden with her LEGO Friends set. I thought of the LEGO fences that we recently picked up in our local LEGO store from the Pick-a-Brick wall. If you are not lucky enough to live near a LEGO store, LEGO has an online Pick-a-Brick at which you can buy individual pieces as desired. I experimented a little and saw that we could build a nice LEGO garden with 13 LEGO fence pieces. Thus, the idea of Fibonacci LEGO Garden was born.

Supplies

I handed over 13 LEGO fences and together we discussed pieces needed for our LEGO garden:

We had 1 LEGO plate, 1 LEGO mini figure, 2 LEGO animals, 3 pieces for the garden gate (a small cheat here as we didn’t have custom gate posts and we built them from several 1×1 pieces), 5 flower clusters, 8 brown 2×2 pieces for tree trunks, 13 fence pieces, 21 various green pieces for trees, 34 white 1×1 pieces for fence posts (2 per post and a few left for a bench in the garden) and 55 multicolor “LEGO dots” for flowers and other accessories. My girl loves those small dots to decorate and help fill small spaces when we load up a pick-a-brick bucket!

You can choose the pieces that work best for you. Just remember to keep with the sequence!

Enjoy Your Garden

Now build your garden from your imagination. Our design turned out lovely. My daughter wants to make  another Fibonacci build, something with 8 wheels next.

Fun Fibonacci Sequence Facts

 

  • * Real name of Fibonacci is Leonardo Pisano (Leonardo from Pisa)
  • * Fibonacci illustrated the nature of this sequence by introducing a pair of rabbits that grew to maturity and produced another pair of rabbits each month after 2 months of life. If no rabbits died, how many pairs of rabbits would there be after 12 months?
  • * You can find Fibonacci series in nature proving that math is not a man-made construct

To introduce more Fibonacci fun to your family, bake up a batch of these cookies.

*May 8, 2013 (5-8-13) was also a big day for Fibonacci fans!
