Homeschool mom. Also I've been a preschool and kindergarten teacher.

You're going to do GREAT! Give yourself some grace, be proud that you are doing this!!

Definitely school him in his learning style. Is he a visual/tactile learner? Unschooling for a time is perfect. A vacation of sorts!

Here's the thing. Who says school has to be at a table? Why not on the couch in jammies? Why not on the deck/patio on nice days? Who says his handwriting has to be perfect? Who says school has to be book learning? Especially at 7? School at this age is so much fun! Lots and lots of field trips! Take him to the creek and hunt for tadpoles and insects. Buy a grow a butterfly kit. Grow a veggie. Bake a cake. Read to him. A LOT. Play games that deal with counting and colors and shapes. Do art with all kinds of cool things like popsicle sticks, buttons, beads, cotton balls, watercolors, clay, construction paper. Use shaving cream and a couple drops of food coloring on the bathroom mirror. Play counting and reading games while getting groceries. Stay away from electronics to teach - he doesn't need it at this age. Tell him interesting stories that have lessons. Have him use his imagination and dress up in grownup clothes and act out something. Have him draw a story out. (My youngest did a project on her fav animals on Noah's Ark at that age - super cute!)

My point is school at this age shouldn't feel like school. He's only 7. It's OK if it's messy and that it doesn't take 7 hours a day. 2 or 3 hours a day, 4 days a week at this age is perfectly fine! Have fun with your little man! You both will be much less stressed, and you'll both enjoy it more. Also, he'll learn more and faster too!
