We love playing with playdough. I think it would be a toss up between playdough and Duplo for which gets played with more at our house. This activity is not complicated but it was fun and kept my daughter super happy while we all battled stomach flu a few weeks ago. As a parent when you find something that is keeping a miserable child happy you roll with it. The trick seems to be really fantastic plastic bugs that leave very detailed imprints in the playdough. Ours were given to us years ago by a neighbor but here is an affiliate link to Amazon for the bugs if you want to check them out for yourself.
Gather your materials. You will need some playdough, a cutting board ( we reserve one just for playdough) and plastic bugs.
Add to the fun with books about bugs. Click through the image below for a great list.
