Math History – Mothers Learning about Technology
Part of Wordless Wednesday…
SISTER BERNARDINE teaches a class of mothers at St. Frances parochial school about the mysteries of the abacus.
The date is unknown, but by the looks of the outfits and the discoloring of the newspaper, I’d suspect it’s a while ago.

Wordless Wednesday: Fibonacci Baskets
I rarely do Wordless Wednesday, but some photos just lend themselves to it!
These are from IKEA.
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?)

Wordless Wednesday: An Example of Count 10 Read 10
In an attempt to join the Wordless Wednesday crowd, I’m sharing this photo. But as you can see, for MathFour.com, this is only a Somewhat Wordless Wednesday.
Before this photo we were discussing size of shirts – a numeracy concept that is visually displayed through the inability for grownups to fit 4T nightshirts on their bodies. Count 10 Read 10 is part of our family’s afterschooling routine.
