The 40 dynamic questions are divided between 9 lessons:
Lesson 1 – Negative numbers in everyday situations
Lesson 2 – Ordering negative numbers
Lesson 3 – Adding and subtracting using a number line
Lesson 4 – Finding the difference between two numbers
Lesson 5 – Adding negative numbers
Lesson 6 – Subtracting negative numbers
Lesson 7 – Adding and subtracting without using a number line
Lesson 8 – More adding and subtracting
Lesson 9 – Multiplying and dividing negative numbers

Topics are introduced in the lessons through the use of text (which is presented in small chunks and can also be skipped) and multiple-choice questions. Stars are awarded when correct answers are given for all of the questions in a lesson. Feedback is given for wrong answers, and the user can then have another go at the question. After three wrong answers have been given the user can either continue attempting the question, or can reveal the answer together with an explanation. Lessons can be done at any time and in any order. They can of course be re-done, and one of the aims the user has is to answer all of the questions in each lesson correctly and at the first attempt.

The Progress Chart shows which questions the user can do and which ones they are having difficulty with. Questions can be selected on the Progress Chart and practised. If the question is red then the “Focus” button appears rather than the “Practise” button, and this enables the user to practise the question until it turns green.

“Question Focus” enables the user to see all the feedback they have been given for individual questions. If the question is either red or orange on the Progress Chart they can practise it until it turns green.

“Feedback” enables the user to go through all the questions they have answered, in reverse order, and see the feedback given. This feedback can also be accessed (as well as the Progress Chart) via the Parent and Teacher areas.

“Random Questions” enables the user to simply answer questions chosen randomly from the 40 dynamic questions contained in the app. The highest number of correct answers given in a single go, and the highest number of correct answers given in a row at Random Questions is kept track of.

When the user has turned all the squares on their Progress Chart green they start the next Round with a new Progress Chart. The percentage completed refers to how close the user is to turning all of the squares on their Progress Chart green in the current Round. Total Completion of Negative Numbers Tutor is represented by completing the Final Test of Mastery (in which all of the 40 questions must be answered without getting any of them wrong). The Final Test of Mastery is unlocked when the user has been awarded five diamonds, and when it is completed the user takes their place in the Negative Numbers Tutor Hall of Fame.
