Geometry vs Correct and Quick Arithmetic

With Geometry: Constructions Tutor learn to make constructions with compass, pencil and straightedge. Learn constructions by watching animated demonstrations. Switch to the practice mode and make a construction yourself to test your knowledge and understanding. The application will check the construction when you’re done and tell you if you’re correct. Let the program confirm your constructions and build your confidence! Smart objects snapping, automatic detection of objects intersections, a unique single touch compass, pinch-to-zoom, and an above-the-finger magnifying glass will make even a complex construction feel easy. There’s no need to use clumsy real world geometric tools and waste one sheet of paper after another to get a perfect result. Make all constructions with just one finger. Every action can be undone and you can restart at any moment. There is no need to aim. Smart snapping will do the job for you. Focus on learning and test your real knowledge, not your motor skills! Watch demos of constructions and practice making: - Lines: copy of a segment, perpendicular bisector, division of a segment into equal parts, perpendicular line through a point on a line, perpendicular line through an external point, parallel line through a point. - Angles: copy of an angle, angle bisector, 30, 45, 60, and 90 degree angles. - Triangles: triangle given three sides, triangle given one side and two adjacent angles, triangle given two sides and included angle, copy of a triangle, equilateral triangle, isosceles triangle, 30-60-90 triangle, median lines. - Triangles & Circles: incenter, circumcenter, incircle, circumcircle. - Circles: center of a circle, tangent lines through an external point, tangent line through a point on a circle, circle through any given three points, foci of an ellipse. - Polygons: hexagon given one side, hexagon inscribed into a circle, pentagon inscribed into a circle.

Correct and Quick Arithmetic does exactly what the name predicts. First practice the basic calculations, and then speed it up. This app was developed for everyone who would like to train and maintain the basic processes of arithmetic. In this app you will find exercises with number bonds to 10, addition and subtraction sums up to 100, and the multiplication and division tables up to and including 10. These are the foundations needed for arithmetic. The ultimate goal is to have committed to memory the answers to number bonds to 10, addition and subtraction sums up to 20, and the tables through 10 (within 2 seconds). For sums up to 100, the way to work them out is automated. No distractions in the app The appearance of the app is kept as simple as possible. Scores are not saved. Experience shows that in particular, those who are not so good in arithmetic, like this! The structure of the levels of mental arithmetic in the app: Number bonds to 10 Addition and Subtraction to 10 Addition and Subtraction to 20 Addition and Subtraction to 100 Multiplications tables from 0 to 5 and 10 Multiplications tables from 6 to 9 Division Tables from 1 to 5 and 10 Division Tables from 6 to 9Division Tables from 6 to 9 First start to practice without timing yourself. In practice mode (X), the correct answer appears after a wrong answer. Wrongly answered sums are always repeated. Only when this goes well will you be able to start training at speed. So first CORRECT and only then QUICK! Stick to the running order of the sums in the app! Practise the number bonds and the sums up to 10 until you can do them all well, and most importantly, fast. These are the most important sums in mental arithmetic!! Level button With this button you can choose between 1 Level or Mix of levels. After a series of sums, a smiley will show how many you got right and how many wrong. The more sums you get right, the happier the smiley is! Ultimately, the reward is realizing just how good it is to be able to do these calculations quickly and correctly. You'll find that the arithmetic that comes later will also go better and more quickly because of it. Correct and Quick Arithmetic is an indispensable instrument, dependent on any method, for learning mental arithmetic! Have fun, and good luck with Correct and Quick Arithmetic! M&M Breuking
