Very large variety on this one. In the grand scheme of things as long as they know most of that as of June before school I am ok. A lot depends on their language development. I have a two year old with poor verbal language but can point to all the shapes and colours I ask for so it is hard to know exactly what info is really in their head. My three year olds know about 10 colours, 8 shapes, can count to 10 - and 15 most days and recognize 1-5 and 10. They know the letter their name starts with and most of the other kids names and a few others. Letters is the last thing I teach so up to this point it is only what they have absorbed more indirectly from our other lessons.

I wouldn't expect a child under 2 to know much of this although some do. Around 20 months seems to be the ideal time to start into the circletime/academics side of things once they are starting to think more beyond themselves.
