Summer plans
It's important to relax this summer and recover.
So give your students 2 weeks off. No studying.
After July 4th, do some light reading.
By mid July, get back into the math textbooks, online practice to refresh on previous school work. Spend about 1 to 2 hours every other day, or every weekday each week.
August 1st, start working on next math class materials every weekday.
So by August 28th, you'll be ready.
