I rarely do Wordless Wednesday, but some photos just lend themselves to it! These are from IKEA. See them here: round, rectangular (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 about some questions…
- 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?
Do you have more questions? Or answers? Share in the comments.
(150 words later my headline is pretty much wrong, huh?)
