We are finishing up kindergarten with our son and daughter, both 6, 4 months apart in age but developmentally farther apart.
They listened in to our family reading time, which included Bible reading, history/geography, and sometimes music or an audio book here and there.
While we didn’t do science together per se, we did take nature walks together, we go camping a lot and “study” nature of some sort every time we camp (and most often when outside while studying a red-headed skink two of my sons caught in a jar for observation). My 2 kindies LOVE IT when their older brothers have animals they can observe.
The skink was let go!
I did something with our kindies that went really well. I had a spiral notebook for each of them that they used for math journaling. Each week I would teach them a concept (even/odd; counting by 2s; 1-20; ZERO; etc.). I tried to do this on Mondays (and most often we did). On Monday, I would teach it in a hands-on way, then later in the week I would write on the board copywork for them to put in their Math Journal that related to the concept. It really helped reinforce and they loved having a notebook like older brothers.
They also did handwriting with this book, which I made from a Currclick purchase: http://www.currclick.com/product_info.php?products_id=21135&it=1
They loved this book so much I am ordering another one for 1st grade. I make it myself from the PDF and have it spiral bound. It has coloring pages that teach about the animals on every other page.
For science read-a-loud with just them, we read from CLP Nature Reader K, which they thoroughly enjoyed. Next year, they will just sit in on our Apologia Astronomy reading/experiements.
I recently began calendar time with them, which has been wonderful. I made my own calendar teaching tool using cards that fit in 9-pocket page protectors. They love it! And I love they have learned the days, weeks, months, etc. They wanted to know every day “what day is it?” “how do you know?” so I knew they were ready.
Everything else was just icing: working in workshop with Daddy, cooking with Mommy, art, music class at church, ballet for DD, taekwondo for DS, etc.
