I found these Number Families at Home Grown Hearts. She explains how to refer to the numbers in the number families (This is the 30s family. That number is in the 80s family) and different ways to use them. They are awesome!
*I printed one set to make a large mat (pictured above) another set that I cut apart for matching on that large mat.
*I also printed a set and cut it apart into the families and attached with a brad to have in the car. (pictured above)
*I also printed some on plain white paper to use with our dot painters.
We’ve had fun counting together, finding patterns on the large numbers mat, putting magnetic pom poms (the idea also from Home Grown Hearts) on certain numbers, and finding numbers while we are in the car. I’m sure there will be a ton of ways for us to use these as he gets older too.
**Update: Home Grown Hearts does not offer this printable anymore. The link above has been fixed to send you to a similar printable that can be used in the same way.
