I've found two websites that I think are worth checking out to work on math skills. Both programs are adaptive so they get harder as students master the math. You will have to create an account for each sites in order to access the activities. The first site is SUMDOG http://www.sumdog.com. The second site is Prodigy Game https://prodigygame.com/play/. I've created a class, to login to our class the code is NPTWRJ. I hope these are helpful.
I'm excited to begin my 7th year teaching at Coonley School. I've been teaching for over 20 years. I love creating projects and lessons that challenge my students.
