IXL is a great program that helps students help with gaps in their education that might be missing. It is also is a great tool to help with reinforcing the current standards that are being taught.
The students will be able to log onto Prodigy Math to help with 5th grade standards and to play games while doing it. Each student has their login and password information. If for some reason you would like it or they have forgotten it please let me know and I will send it to you!
