Over the Break I looked at several online math programs. These are the ones that I found: XtraMath
This is a math fact fluency program. The online program is FREE, and extremely easy to set up. Students practice at their own level for a short time period per day. Tracking Reports can be sent to both parents and teachers via email. The tracking information and progress is also available online.
IXL Math is online math skills practice where the student is evaluated at his/her level and progresses at his/her own speed. There is a free offering and a membership. Ability levels are arranged from Pre-K through eighth grade and then through Geometry.The membership version of IXL tracks/reports student progress to teachers and parents. The site is very similar, visually, to the Adapted Mind site (listed below). A membership for a classroom runs about $200 a year.
Online Reading and Math: The READING portion is a “Membership Required” area but much of the math is free. You may purchase a membership for about $200 per year. This site is similar to IXL, except it offers a reading skills section. Additionally there are good instructional videos available. There is a limited (5 students) free trial.
Khan Academy is free. It is cumbersome to sign up your students but once you have done that, the program itself is manageable. It is geared toward upper grades to adult learners, but I used it last year for fourth grade and it was adequate. It is not as “entertaining”, nor as engaging for younger students as some of the other sites.
