Below I have included the websites that I have played around with and also given my own quick explanation (in some cases, I have shared age-level suggestions too.) One word of advice: Make sure that all of these games work on your school computers if you have strong filters set up. There is at least one of these that my students will only be able to access from home due to restrictions at school.
Check it out and have fun!!
