You chose where to work. You can go back or skip forward, at any time, to get questions that are appropriate.

From:
Expand 5(x + 6) or -6(x - 3)

through:
(9x + 5)(x + 3) or (2x + 1)(3x - 4) or 2(5x + 6)²

up to :
4x(3x + 1)² or -3x(3x + 2)(3x - 2)

The numbers are random, so you can repeat a question as often as needed, until you have confidence in your ability, and you know you will remember the skill.

There are 'Hint' & detailed 'Show Me' screens to remind you when you have forgotten.

Wrong answers often get helpful responses to help you get it right.

Great for individual use.

In the classroom the teacher can state the question numbers to work on.

Those students that need to can start with easier questions.
Those who finish quickly can move on to more challenging ones.

The App shows a list of correctly answered questions like this:

Correctly answered: 16-22, 25-26, 30

so the teacher can monitor progress.

The App generates the questions and marks the answers, leaving the teacher free to work one-to-one with individuals or groups of students.
