What is Mr. Nussbaum?

MrNussbaum.com is an educational website designed for teachers, parents, learners, and students. It covers most elementary and middle school subjects and is useful for all learners. 

Regarding the Privacy of Children

MrNussbaum.com does not collect any personally identifiable student data. Some of our educational activities may ask users for a name or code name for the purposes of personalizing a certificate or for a printable, non-recorded  score report. 

By default, our resources do not collect student data. 
Within fifteen of our games, teachers have the option of recording and reviewing basic student statistics such as score, number of times played, and average score, but must initiate registration of an account. Student “names” are limited to initials or a three-character code determined by the teacher or parent.
For example on a game such as Ultimate Speed Math, a teacher or parent might see that student “SBR” scored 14. This data is solely for teacher or parent review and is not analyzed, exported, or used in any way.
We do not collect, ask for, or store student names, addresses, gender information, identification numbers, birthdates, grade level information, email addresses, phone numbers or any form of personally identifiable information.
