Spelling Program: Spelling connections

https://www.spellingconnectionsonline.com/

We haven't had any need to actually study spelling yet. So far I have a bunch of kids who just absorb spelling. So I don't know how well this would work for kids who really need to study spelling.

I do like the proofreading option, though! Traditional spelling programs don't teach you how to find misspelled words, and that's important.

PE and attention training

This program is supposed to teach PE and also train children's brains in attention and focus. It has been recommended for Gifted kids with symptoms of ADHD.

https://c8kids.c8sciences.com/

This is not technically fully free. It's a "pay as much as you want" program that you can put in $0 for. You don't have access to the entire program for $0, but when you sign up it tells you what you have access to and what you have to pay for greater access (mostly of reports to help you assess your child's strengths and progress).

Onomatopoeia

Everywhere around the world, people try to explain sounds. We all have words for what a mouse says, what a rooster says, what an ambulance says.

This site has recordings of children from all over the world, making the sounds for things--trains, animals, ambulances, etc.

http://www.bzzzpeek.com/

It's really fun to hear what native speakers in many different languages say that roosters say. And mice.

Great, fun site.
