Could do letter/# recognition Toddler Approved!: Word Family and Color Slam - Back to School Basics. A simple game we played with my pre-kinder and toddler. The pre-kinder learned about word family words while the toddler practiced her colors. So fun!
DIY Portable LEGO Kit with Free Printable Activity Cards. I like this for school, older kids can have activity cards to create planets/atoms/molecules/fractions, younger ones can practice fine motor skills.
