If you haven't heard of Moebius Noodles, I highly recommend you check it out!
From the Moebius Noodles blog:
We are creating an advanced and accessible math book for young kids and their parents, called “Moebius Noodles” and an online knowledge exchange hub to support it. It’s an off-the-beaten-path travel guide to the Math Universe for adventurous families. A snowflake is an invitation to explore symmetry. Cookies offer combinatorics and calculus games. Floor tiles form tessellations. The games in “Moebius Noodles” draw on these rich properties of everyday objects in ways accessible to parents and kids, even babies. As the world turns into a mathematical playground, it transforms, one family at a time.
The most recent post has a fabulous menu for 'playing math every day' for the week of November 28 through December 4. Activities include playing ball outside and then exploring a type of fractal called Apollonian gasket, fun subitizing activities, and starting a math journal.
