*Below is the link to access iReady lessons which are specifically designed to meet your child's individual needs. All students have been provided with a Clever login badge which allows access to iReady and other educational apps. It is recommended that the students complete at least three Math iReady lessons per week. I will be monitoring the students' progress daily and will make modifications as needed.
*If using an iPad  Have the student install the iReady app on their iPad. Have the user access Clever through Safari then click on the iReady link. It will prompt asking if they want to open the link in the iReady app. Have them click "Yes" then they should be good to go.*
