Get understanding of the line with numbers.

The line with numbers

A number line is a line that displays all the integers in order from low to high. First, you practise with up to 5 then finally up to 20. To understand the concept of the number line, you first get short exercises, where you have to add each time the correct number omitted on the line.

Example question to learn to split numbers.

To split numbers

You learn to divide numbers with short exercises. You have to break the number into two other values, which together forms the first number. In this way, you will learn the concept of adding and subtracting of numbers.

Example question of splitting numbers by using a train.

Splitting by using a train as an example

As soon as you understand the concept of dividing numbers, we will count with numbers above five. You will work with a train as an example, where you have to place cubes on the wagon. In this way, you will learn that 4 + 2 is actually 5 + 1.

Example question of an addition with passengers at the bus stop

Practice addition and subtraction with passengers at the bus stop
