Correct and Quick Arithmetic

Correct and Quick Arithmetic

Correct and Quick Arithmetic was developed for everyone who would like to train and maintain the basic processes of arithmetic.

In this app you will find exercises with 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 table of 0 has been added to make children more aware of the number 0.

The ultimate goal is to do sums (addition and subtraction up to 20), and tables through 10 with a very short time limit (within 2 seconds) resulting in answers to be memorised in the human brain.

For sums up to 100, the way to work them out is automated. The threading method is the best way: 28+13 = 28+10+3 = 38+2+1 = 40+1 = 41

Asterisks indicate the level of difficulty.

For whom is the app intended?

The sums in the app deal with lesson material appropriate for primary school children aged between roughly 6 and 9 years. They need to remember this lesson material throughout their entire primary school time!

In addition, this app is eminently suitable for secondary school pupils who did not practise these basic calculations enough or who have since forgotten them.

The app has also proven itself to be extremely useful as an aid in remedial teaching and as a 'remedy' for dyscalculia.

What is the best way to use the app?

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!

You decide which type of sum you want to practise.
You don't know? Stick to the order of the sums in the app.
It is better to practise one type of sum repeatedly, and work on your speed, than to practise different types of sums at random. You can keep using the sums in the app until they are well and truly lodged in your memory!

Practice option for multiply/divide

Practise everything in one table: the 2 times table, the 2 times table back to front, and then divided by 2. This will make the relationship between these tables clearer. Try it for yourself!

What is the reward?

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 realising 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!
