H was slower with number familiarity as well at firt but we just played with a number puzzle and practiced 1-10 first doing silly things like glueing beans on a 1 and so on, writing it, and of course number books. I tend to not like to push my kids on concepts they don’t get and give lots of resistance on. It seems like if we wait a while, the concept is then re-introduced and is understood almost effortlessly. Of course there are things worth pushing in a good way, but you know what I mean.

It’s so funny because things I felt like I spent a lot of time with H on, her little brother has picked up practically through osmosis.

Nice website.

Children should actually start learning to write in lower case letters first and the upper cas only as needed. In the classroom we introduce the letters in this order:

this is because each letter leads to learning the next letter (to make a c it’s a half circle, and a is a c with a short line, etc…)
But great that you found a site that would help in this!
