Every XrMath App provides a virtually limitless supply of question to let students DO math.
Intended for classroom use but also suitable for individual work.
Questions can be repeated as often as needed - the numbers are random.
The list of questions is color coded to show the degree of difficulty. The question difficulties range over several grades.
Those students that need to can start with easier questions.
Those who finish quickly can move on to more challenging ones.
The teacher and student chose where to work. They can go back or skip forward, at any time, to get questions that are appropriate.
There are tutorial screens - intended for revision.
Every question has a Example screen showing a worked example, but with different numbers.
Questions answered correctly are ticked so both teacher and student can monitor progress.
Extra ticks are displayed when questions are repeated.
When the app is restarted the ticks are removed, ready for the next student.
The App generates the question and marks the answer, leaving the teacher free to work one-to-one with individuals or groups of students.
