I have tried so many ways to record scores from math homework. The process that I use now has been very efficient. I place the answers on our textbook SMARTboard notebook software. I operate the SMARTboard using my iPad2 and the SPLASHtop app. I collect the student's score after they correct it by having them enter the information in a Google Form called Homework Submit. To help with authenticity, I click the "Require sign in"
After data is collected and after the school day, I use my iPad2 to view the inputted data and place it into the grade book which is located on my laptop.
Sounds confusing? But productive!
