Brainzy- this is actually a website that I came across and I think it looks awesome! I can't wait to try it here at school!
ABC Mouse- there is an app and this is online. This is a website that you may see on tv. I used it in preschool for the songs and the kids really enjoyed it.
Toca Builder- This is one of my all time favorites. Toca has a bunch of different apps, but I have used this one in the past. It always makes me think of Mine Craft.
Moose Math- This has a lot of different math skills on it and the graphics are very catching.
Kiko's Thinking Time- This is more for the cognitive learning that our little ones need. It challenges them in different ways and I think it looks like a lot of fun.
Splash Math- This app has a few different math skills on it and it's FREE!
Reading Raven- I struggle with finding apps that are strictly reading and that actually have books on them. This app is another one that I haven't tried, but I really want to try it here at school.
Gappy's First Words- I like this one for sentence building and the kids really get to use those Jolly Phonics sounds to create words.
I hope you all find these useful! Let me know if there is a certain area that you are looking for an app or website. Not only can I help, but there are other teachers here that are great with this stuff!
