While working on problems, students are guided through the process of completing the algorithm. Each step must be completed correctly without an error to get the problem "correct". Once the student has answered 10 questions complete "correct" they have completed the level for the day.
Data is stored online showing progress of students throughout levels that are available to them.
For students to login, they type in the class number, click their name, type their password, and proceed onto their practice for the day.
This site is quick to set up for you and your class, saves data about your students daily practice, and provide students practice opportunities while mastering the standard addition and subtraction algorithm.
