## Resources

This is a collection of digital resources for teachers. I am always building and adding to this. Recommendations are gladly accepted. To see a list of specific blogs and authors, check out my blog roll.

#### Research and Articles

- Annotated Bibliography - A GoogleDoc with links to articles I like
- Quotations - Math Ed. related quotations I like (Not much here yet)

#### Collections of Lessons and Problems

- NRich - Large collection of good problems. Can be tricky to navigate and find problems though
- MARS - Mathematical Assessment Project. Great for investigative lessons and performance assessments
- Open Middle Problems - Open-middle problems sorted by grade level and CCSS
- Yummy Math - Focuses on problems relevant to the world, no psuedocontexts
- NCTM Illuminations - NCTM designed lessons
- NCTM Brain Teasers - Collection of MANY great problems. Better for challenge problems
- YouCubed - Jo Boaler's Stanford based education lab
- Estimation 180 - A large collection of images where you can make estimates. Many have context clues that can help (such as a bannister in the background when estimating someone's height).
- Visual Patterns - Simple patterns shown visually to inspire algebraic thinking (from Fawn Nyguyen)
- A list of "Tiny Math Games" compiled by Dan Meyer
- Math Would You Rather - Given a choice, make a mathematical reasoned decision (ex: pick a line at the gas station)
- Daily Desmos - This websites hosts gifs of Desmos graphs and challenges you to recreate them
- Which One Does Not Belong - Groups of 4 things (numbers, figures, pictures, etc.), come up with rules for why each one does not belong
- #MTBoS Created Tasks
- 3 Act Math Tasks:
- NAEP Question Finder - Questions from the National Assessment of Educational Progress test
- Problem Attic - Lots of problems from standardized tests linked to the content they cover. Lots of free stuff, but some problems are behind a paywall
- Art of Problem Solving's Contest Math Archive - More contest math problems than you could ever need

#### Puzzles and Games

- NYTimes Crossword - Monday is the easiest, Saturday is the hardest, and Sunday is bigger (about as hard as Thursday) and has a richer theme
- Yajilin - Draw a complete loop on a grid (rules)
- Slitherink - Draw a complete loop on a grid -- feels like minesweeper (rules)
- Find the Factors - Sudoku like multiplication grids where you fill in the blank
- Array puzzles with rectangles - good multiplication practice

#### Utilities

- Wolfram|Alpha - Really powerful calculator in the form of a search engine. Connected to lots of databases. Try searching for a first name. For example, Jessica. You may also recognize the loading pattern as Conway's Game of Life
- Circos - You have probably seen these circular weblike diagrams. Make your own
- Generate LaTeX equations as images - Great for quickly making a LaTeX equation. I use this for making nicely-formatted equations to drop in Google Slides

#### Paper Types and References

- Unlabeled Number lines - These have a transparent background. Just crop out the number lines you don't want and add labels
- Unlabeled Coordinate Plane (One with 1st Quadrant Only)
- LaTeX grammar and commands
- Dot paper
- How to use Algebra Tiles
- Common Core Coherence Map - Choose a standard and see which ones it is naturally connected to. Also, tasks are shared for each standard
- Blank Equation/T-Chart/Axes
