I rarely do Wordless Wednesday, but some photos just lend themselves to it!

These are from IKEA. See them here: roundrectangular (if gotta have a set or two (or seven) of your own).

In case you’ve not yet taught the Fibonacci Sequence, it starts with 1, 1 and then each next number is the sum of the previous two numbers:

• Next is 1 + 1 = 2
• Then 1 + 2 = 3
• Then 2 +3 = 5, etc.

• How many sets do I need for the next number? (A set from Ikea has 1, 2, and 3 in it.)
• How many sets do I need for each number after that?
• Is there a pattern? Like for the 12th number I need 12-2=10 sets and for the 17th number I need 17-2=15 sets?

(150 words later my headline is pretty much wrong, huh?)

Great dreams, I’m sure!

Did you see all the other Fibonacci stuff? Like the birthday party?

I see questions like this about baskets and think, hmmm, Excel could check that.

Here is the spreadsheet if you are curious. It works out how many new sets to purchase for each additional number. As with fibonacci numbers, the number of needed sets grows quite rapidly! Need to buy 39 sets just to fill the 13th number. Total of 102 for all first 13 numbers.

Fun, Danny! Thanks for sharing that.
