What about younger siblings? Hey! I'm doing school!

The young woman I'm home-schooling this year, Lacie, has four younger siblings.  The three year old likes to do school with her.  Little Sister has a tremendous attention span!  Now, I'm not an early childhood expert.  My background is with secondary science, Biology, Chemistry, etc.  But, I've worked with many ages at VBS and summer Science Camp.  So, Lacie and I are making up lessons for Little Sister. We made a short list of immediate goals: color recognition, shapes, number recognition, counting, and letter recognition.  Little Sister has mastered many of these already.  Before we branch into farm animals, weather, seasons, etc., we need to make sure Little Sister has mastery.  So we assembled cutting strips, practice letters, colorful objects to sort, and puzzles.  I had extra Lego Duplos. Frugal Fun for Boys and Girls has terrific ideas for Lego Duplo Math cards.  The child can count and do color patterning with the Duplos.   Another easy lesson is Do a Dot with printables.  Children can use bingo markers or  office dot stickers.  We are using the dot stickers; they are not messy and exercise fine motor skills.  I made simple paper books for VBS.  I stapled cardstock and copier paper to make the books.  Little Sister can use the book to glue pictures, stickers, stamps, scriptures, coloring etc.  The little book is a record of some of the activities and skills she has mastered.  Look!  Little Sister gets to be a big girl and do school with Lacie!  Lacie can focus more on her own work.
