Fibonacci, a mathematician who lived during the 1200s, developed a number sequence named after him. Each number is added to the previous number to get the next number: 0 1 1 2 3 5 8 13 21 and so on.

Grade 2 Dewey Detectives
The Dewey Decimal system is a way of sorting nonfiction books. I don't expect my students to memorize specific numbers; that's what the online catalog is for. I do, however, want them to understand how certain topics go together. At least according to how Mr. Dewey thought they did.
Second graders each got a search term and a number from a "hundreds." They had to work with kids who had the same number to figure out how their subjects could be classified under one major label.
Can you solve the puzzles?
- 500s: planets, electricity, magnets, elements, weather, rocks, dinosaurs, bugs, ecosystems, plants, animals
- 700s: music, jokes, origami, drawing, magic tricks, football, chess, yoga, knitting, dance
- 900s: maps, ancient civilizations, countries, states, wars, explorers, The Titanic disaster, flags, American colonies
K Book Matching
A big part of information literacy is being able to recognize patterns and to categorize facts, sources, etc. We start work on these skills in kindergarten, and it is leading up to them being able to choose books from the shelves on their own, versus from the selection I put out.
This week, students each got an Everyone or Early Reader book and had to find another student whose book was in the same category in some way.
