I prefer being really flexible for anything I do with my toddlers so I don't follow a specific program and we are constantly changing and adjusting. I'm sure that anything I've posted in the past we finished or stopped doing a looong time ago.
But O, my almost 3 year old, wants her own "class" and it is really helpful to devote 20-30 minutes to my two little girls before starting school work with my older kids.
We start by reading books together. They will usually pick a few that they are currently interested in, and I pick a few as well. The ones I pick we usually read for 2-4 weeks at a time, and have more of a learning aspect to them. Sometimes we read the books and sometimes we look at the pictures. Books I've picked for November:
A book from My First Bob Books Pre-Reader Collection which includes the Alphabet set and Pre-Reading set -- I don't read these to teach my girls to read, but because they are simple and have a lot of familiar pictures for them to identify. They also like them because my older kids have used the other collections as they were learning to read, so my girls think they are using "big kid" stuff. And there are stickers.
First Rhymes: A Day of Rhymes with a Different Twist by Lucy Coats -- Author has re-written favorite nursery rhymes: "Humpty Dumpty stood on his head, Humpty Dumpty fell out of bed . . . "
Go, Dog. Go! by P.D. Eastman -- has colors, opposites, and lots of DOGS, my girls' favorite animal.
Before Five in a Row books -- The Five in a Row books are wonderful, but I prefer to just use the book lists for wonderful picture book ideas. Jesse Bear is very well-loved and O is always asking for it!!
After we've read for a little while we play games. Right now they like laying the memory cards face up and making matches. In the past we've done puzzles, played with babies or other toys, and sometimes we also do activities like Head, Shoulders, Knees and Toes or Ring around the Rosies. We also sometimes sing songs together - they are really getting into a song we are learning in anticipation of Christmas called Christmas Bells.
After about 30 minutes I let them pick some toys from the closet that are just for school time -- we have a house set, barn set, Noah's ark set, space ship set, blocks, puzzles, and quiet books. They also will join in when we are doing something they can participate in such as coloring, nature walks, listening to stories, etc. 




I didn't use the toys the first week we were trying the class time, and Olivia wanted class time to go on and on, and would throw a tantrum when I'd stop. Now she has something else to focus on, and happily plays with her toys. When she tires with one of the toy sets, she and I clean up, and she can pick another one if she wants. Most of the time she moves on to the other toys that are around all the time. As part of our morning chores the kids to clean up their bedrooms, and this helps Olivia be able to find the toys she wants to play with- like her babies and baby stuff, Barbies, stuffed animals, etc.
Sometimes Olivia wants to be working with us while we are doing school, so I have several activities for her to do then. I try to get her to do something similar to what the older kids are doing. When they are reading she can look through books, and there are many days she will look through one book after the other, until she empties a book shelf. When they are writing or drawing, I'll give her a coloring page about that week's theme, or we have lots of coloring books and paper she can pick from. She loves to take her turn on our big whiteboard after the kids have finished using it, but we also have a couple small whiteboards she can also use. We have lots of puzzles that she can do- some on her own, and I can help her put harder ones together when I don't have to completely focus on the older two, such as when they are listening to a story or working on something on their own.
Once school is over I make a point to spend a few minutes with her before I jump into making lunch or doing household stuff- we read a story, chase each other around the house, play ring-around-the-rosies, whatever comes to mind.
