Parents here are some sites that we use in the classroom everyday. We use different ones each day so I will be uploading the same concept but from different sites.
This website has a lot of fun educational games for a variety of grade levels, but I have put the site for Pre-k.
Their is a paid portion, but the free part includes a lot!
You may use my login for your child. They each have a profile already. Just have them find their name and they can do their learning path which is the mouse and they can do their lessons.
