2 and 3 year old learning activities?

For teaching the alphabet, here is a site where you can print free pages with each letter for them to color. For now, just focus on one letter a week and try work on the sounds with them every day. Point out things in your house that start with that letter---or better yet, label LOTS of things in your house and point out all the ones that start with whatever letter you are working on. Read lots of books to them, and have them find the letters and point to them. Also, get some lined paper for them to practice writing (you can find free printable worksheets for this too). Pay close attention to the way they are forming their letters and correct them right away if it is wrong. The better they learn the correct way to write letters, the better words will flow for them when learning to read and write. For colors and shapes, you can make flashcards and practice them every day. Rewards are always really good too. Each time they do something correctly, give them a treat. (I use a big tin full of teddy grahms and a jar of jelly belly jelly beans) They love to be correct AND rewarded for it! Hope this helps! : )

when my toddler started he could not sit for stories now we read together, we spell store names from store marquees we play i spy all the time and we visit the library all the time

In that situation i think the best learning method is, for the child that knows all these stuff be around and do everything along with the other, kids love doing what other kids do. let the count together,play together whenever u teaching teach them all at once trust i have done it before with my neice and a child i care for 2 years apart from eachother and they are almost on the same paste
