ProjectsMATH FACT FLUENCY
- I can't stress this enough, MASTERY is expected with all basic facts!
- Please make sure your child is studying their math facts. Knowing their math facts will strengthen their skills and help them understand all the new concepts they will be learning.
- Plan to practice a minimum of 3 times a week for 10 minutes a session (on-line sites and/or games).
SplashLearn
This school year I plan to use an educational program called SplashLearn to supplement their math learning. We will utilize this program in school, but I may give additional assignments that students can work on at home. The version we will be using will give us access to assigned practice, math facts, and progress reports.
