Our activities sometimes aren't anything special, they could just be 20 minutes of focused puzzle play or reading. I just like to be intentional about doing an activity each day so the weeks don't go by without me realizing I haven't interacted with my kids besides daily routine. I think that free play is imensely valuable, but I also see a place for "learning/exploring time" each day.
The other night I realized I had some flour in our cupboard that has been in there for quite awhile. Instead of throwing it out (does flour go bad??...) I decided to let the kids play with it. It started out dry and using a sift, and moved to adding water to the flour. From there we also added food coloring. Both H and J loved this activity at the ages 9 (almost 10) and 2.5. H kept saying, "I love this! This is so fun!" J really didn't say much because he was too busy playing and running his hands through the goup. They played for over an hour and J could have probably kept playing for another hour.
we went from this:
to this:
*Helpful tip: Do not wash the flour/water down your kitchen sink when you are done... it hardens up like glue and will clog your pipes! To clean up, I threw the flour outside in the bushes and had the kids wash their hands in a bucket of water that I then threw outside as well.
