Aimed at Secondary (year 7 to 13) A very well laid out, colourful mathematically sound app that allows students to individually learn concepts and to put them in to practice.  Good use of colour to illustrate to the student to which level they are indicating, the app takes the student through a steady progress of demonstrating a concept and allowing them to complete a number of problems to practice that concept. There is plenty of help within the app along the way if an incorrect answer is given. The app encourages the student to go over again the work they have done before to practice the concept they have learnt. 

Teacher Review

Good use of colour to show the student which level they are indicating. If you leave the app you don’t go back to where you were this has been done on purpose to re-enforce previous learning. The instruction and problems sections are very well laid out with a good use of text size and type. It is good to see that a background colour other white has been used. The student can decide which section they want to complete as the navigation allows them to go anywhere within the app at anytime. They can skip the sections they may know to the bits they may need practice on. They are tutorial sections followed immediately by problem sections that the student completes. The sections covered by this app includes;

Area, Perimeter, Triangle, Parallelogram, Trapezium, Compound Area, Circumference, Circle Area, Sector, Area units, Volume, Prisms and Volume units.

Overall a very neat and concise app that is not cluttered with needless graphics or pop ups that can distract the learner from the task in hand. Put together with other apps in the series and it becomes part of a collection of very useful learning tools.

From the Developer

Every XrMath App provides a virtually limitless supply of questions 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.
The question selection list is updated to show how many times each question has been correct answered, so both teacher and student can monitor progress.
The App generates the question and marks the answer, leaving the teacher free to work one-to-one with individuals or groups of students.

In this app the questions are carefully graded from easy up to difficult in 21 steps.
