Disclosure: I was sent copies of these books in exchange for an honest review. All opinions are my own.Independence Day is past. Summer is quickly passing. Kids are enjoying their break from school as are teachers. But what is happening to your kids' math ability this summer? According to Learner.com, 70-78% of elementary students experience a decline in math skills over the summer. (Source) Most schools now assign summer reading to prevent the summer slide in literary skills, but does your child's school assign summer math? Most high schools do these days. Now I am a huge advocate for a break! I love summer! It is my favorite season, and I remember the days of having nothing to do and being able to hang out with friends and relax. However, summer slide is real. (There is a slide after any vacation and the longer the vacation the more skills lost.) There are things to do to help with the math summer slide even if your child does not have math summer work. Today I am going to review two great resources for different ages to help with the summer slide or just give extra practice to two ages groups: middle grades (8+) and high school. These books are amazing resources to help with math skills and also can give students extra practice or a leg up on the upcoming math year. At the end of the post, I have a roundup for different ages math products and activities to try this summer to keep your child's brain thinking mathematically.
