will always equal 7, 4x5 will always equal 20, and so some rote learning (learning by repetition and/or memorisation - in this case with worksheets) is a suitable and efficient way to practise and develop mathematical skills and techniques so that they become second nature; hard-wired number facts in a young person’s brain. You don’t have to think when asked what is 2+2: you just know that it is 4. The sooner that a child just knows certain number facts, the better, but that knowledge comes only through practice.

Some people find it easier to think of the decimal point moving, rather than the digits moving. In the example above, the decimal point stays in the same place and all of the digits shift to the left.

Rote learning is often frowned upon in modern education - understandably in most subjects - however with elementary mathematics some rote learning is essential. Similarly with mathematics, once strong foundations have been built, a whole new world opens up before a child. Without the right basic mental tools a child will always struggle with mathematics, and therefore with many other subjects too.
