Spirograph
Ages: 3 and up
This is the original Spirograph, which is still probably more modern than the one I had when I was a kid! I recommend this for kids and adults who are interested in designs, lines, and patterns. YOu can make cool designs like this!

Melissa And Doug Shape Sorter

Melissa And Doug Shape Sorting Cube
Ages: 18 months to 4 years
This is a classic toy that allows children to practice problem solving as they figure out which shapes will go through which holes. The lid is made to fit loosely so that tiny hands can pry it off and dump the shapes out to start over.
This product won the Scholastic Parent & Child: Teacher's Picks in April 2006.
Although this is a classic toy for toddlers and preschoolers, it could definitely be used for older children as well! It can help children with various special needs practice learning shapes, colors, problem solving, and fine motor skills.
