Favourite Educational Resources

Highlights:

This is where parents should start:

1. Talking Math with Kids. Why and how to talk math with kids, especially informative story examples. Make sure to check out Which One Doesn't Belong.
2. Explorations: Peter Liljedahl calls these numeracy tasks. Download one and talk about it with your kids. Even though he has grouped by age, don't be restricted to those suggestions. In particular, older kids (and adults) can still get a lot out of discussing even the "K-3" scenarios.
3. NRICH: healthy math snacks. go online for 5 minutes and you will have a great activity to do with your kids. They also now have Wild Maths
4. Let's Play Math (Math Teachers at Play): curated linkfest that will take you to other great sources of ideas. This is for when you have time to browse and plan. The book, Let's Play Math, is also a great place to get started.
5. Mike's Lawler's blog: wonderful collection of (mostly) videos of his family working through problems, puzzles and mathematical explorations. 

I just found mathpickle and am debating where to put it on this list of highlights. Maybe tied for 5th?

Mindset for teaching math at home

1. Growth mindset and math (Jo Boaler)
2. Talking Math with Kids http://talkingmathwithkids.com/  
3. Kids Quadrant http://kidsquadrant.com/
4. Mathematicians talk about what they do with their own kids
5. Mathematicians talk about their own childhood experiences

Philosophy (of math and of teaching math)

1. Math habits of mind: one of my favorites that I cannot recommend highly enough
2. Lists of Math habits of mind: worthy companion to the previous item
3. Mathsemantics: a really great book
4. Lockhat’s A Mathematician’s Lament: http://www.maa.org/devlin/lockhartslament.pdf

Videos

1. Ok, these are gifs, but anyway a cool way to kick-off a conversation: http://solvemymaths.com/category/maths-gif-of-the-day/ These are also awesome: http://blog.matthen.com/archive
2. Vi Hart. Absolutely love her material. Here personal website and here is one youtube channel (I think she has another). A particularly fun one about snakes and graphs. Vi goes fast, so you will probably watch many times, go explore what she's talking about, go back and learn more, repeat.
3. Mathematical Etudes. I'm putting this here because I recommend starting with the videos. There are accompanying notes that add some explanation to what you see on the video. Plow through the rough translation and talk about how cool all this stuff is.

Teacher resources:

These are either things that are only available for teachers or, IMHO, won't really benefit parents. I haven't organized them very extensively as this has not been our area of focus.

Summer programs

• PROMYS for Teachers: http://www.promys.org/pft/
• Park City Math Institute: http://pcmi.ias.edu/program-index
• Princes Teaching Institute residentials: http://www.princes-ti.org.uk/

Things that initially looked good, but we don't use them.

• London Knowledge Lab (future of digital learning): http://www.lkl.ac.uk/cms/index.php
• inspired by this http://www.ams.org/notices/201210/rtx121001408p.pdf

Special sub-category: gone but not forgotten

• Rolfe Schmidt blog (now dormant, but interesting perspective from enlightened Dad-teacher) This introduction to modular arithmetic was particularly interesting: http://rolfeschmidt.wordpress.com/2007/05/15/rainbow-arithmetic/#comment-3582
• Marshall Hampton wrote another blog that now is dormant: http://neutraldrifts.blogspot.com/. He posted an interesting set of worksheets that he wrote for his daughter.
