Math Summer Resources
The resources can help keep the concepts and skills that students have learned sharp and even stretch what has already been taught this year into some new topics.
Your teacher may already have a Khan Academy course set up, and if so, this is great. If not, this service has "Math By Grade" which organizes the content in a very friendly way.
This site has a collection of tasks that really give creative problem solving skills a work out. These tasks can often force students to think a little outside the box when doing the math, which is a great way build understanding.
