I write a math enrichment resource book for my daughter�s school. I�m looking to update the book for next school year. I�d appreciate any suggestions for new resources I can include. I�m looking for materials released in 2012 and 2013 including toys, board games, video games, apps, websites, and books (non-fiction and fiction). Although the book is aimed at fifth and sixth graders, I make a digital copy available at our PTO website so materials cover a wide range of grade levels and math abilities. If you�d like to see last year�s book, you can download it here: https://sites.google.com/site/polan...-math-enrichment-family-resource-book-1. Thanks in advance for your help.
