I read a few blogs about Moms who actually plan and execute lesson plans for their pre-schoolers based on Montessori methods of teaching. I am a big fan of Montessori and of these Moms, but I am usually not together enough to plan things ahead of time. However, I put together a few activities. I gave Kiddo this bean/pasta sorting activity using his giraffe chopsticks and also a lacing activity.
For the lacing activity I just punched holes in a plastic plate. It was a bit challenging, and I imagine using a paper plate would be a lot easier.
For the bean and pasta sorting, I'm guessing the (terrible) photo is self-explanatory. For this activity you can either have the child place the items in the muffin cups using chopsticks (or fingers), or have them take them out. Or both. Or allow them to explore the materials however they wish. And afterwards, if the items are all over the floor, teach him how to use a broom!
