I made a simple graphical web app to help my 5 year old (now just turned 8) understand basic arithmetic concepts, and it's been very successful. You can see a session of us working with it together at https://www.youtube.com/watch?v=t3doY76KEVk . (note that I made a web cam button, so it will put the video of us behind the app itself, so I could screen capture the app and it shows me and her as well) The video is a full half hour (two sessions), and even if you just skip around it's pretty cool to watch how the concepts seem to click for her.

You can use it at https://pianop.ly/mathLesson/ and if anyone is interested I'll put an MIT license on it and put the code on github.

It started out with us using pennies laid out on the table, then when I realized how tedious it was, I started using GIMP, then when realizing how tedious that was, made a little app. This is the earlier version (first GIMP, then a cruder version the app) https://www.youtube.com/watch?v=_VDn54vPNSk
