Lumio is a wonderful site/company for online Math Resources & mobile games. There are 7 easy to use fun iOS games that focus on a wide variety of Math skills such as: telling time, multiplication, decimals, etc. These games are designed for students 5-11 yrs, aligned to Common Core Standards, and generate detailed reports. This is an ideal way to introduce Game Based Learning to the classroom as well as work in a BYOD or 1:1 environment.
