For the past few months, we have been have been having preschool time at home. To get started, I bought each of my kids a spiral notebook. Everyday, we start out by tracing a letter from the alphabet in their notebooks. (I write the letter with dotted lines in pen, and my kids trace over it with a marker or crayon). Then my son draws a picture of something that starts with that letter and I tell him how to spell it so he can write it out.
That letter becomes our theme for the day. I try to incorporate snacks, activities, and books that start with that letter.
Here's some more pages from my son's notebook-
We practice letters, numbers, shapes and colors a lot. These are all simple preschool ideas, which take hardly any prep and promote fine motor skills and good practice.
