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

Tap two number pals that make 10 and watch the dots fill a ten. Calm math games with no timer, no ads, and no tracking. NumberPlay is free, with no in-app purchases. Each number pal is a number from 1 to 9 with a ten-frame belly, so children see how many as well as which number. MAKE TEN - Tap any two numbers that make 10. Each ten flies into a hundred, and every hundred earns a sticker to keep. - No timer and no lives. A pair that doesn't make ten shows why on the board, then you simply try again. - Help is one tap away and shows a little more each time it's asked. - The game grows with your child: the first hundred uses a few friendly pairs, and later hundreds use them all. ADDITION SPRINT - An optional 60-second round for practicing facts your child already understands. - One star for every right answer, with no speed bonus. A slip never loses a star. - A rocket climbs toward your best, and the round's stars land in ten-frames at the end. STICKERS - A sticker for every hundred, in ten designs. - Five more stickers, one for each pair that makes 10, earned by finding it without help over a few days. MADE FOR CHILDREN - The games are played with pictures, dots, and sounds, so children who are still learning to read can play. - Each pal pops at its own pitch, dots tick as they move, and every ten lands with the same chime. Grown-ups can turn sounds off in the Settings app. - Mistakes are safe, and help is always free. - Works on iPhone and iPad, with VoiceOver, larger text, and Reduce Motion. Short lessons to read together cover making 10, doubles like 6 + 7, finding the missing part, tens and ones, equal groups, word problems, and adding in your head. No ads. No tracking. No accounts. No in-app purchases.
