Solution: let us look into the steps given below to understand addition on a number line. step 1: consider the first number (1) as the starting point on the number line. in order to add 1 2, mark 1 on the number line. step 2: now, from the first number jump by the number of units equivalent to the second number towards the right. The number 1 is 1 unit away from 0. the number 2 is 2 units away from 0. the number 5 is 5 units away from 0. so on and so forth. number lines can also help us solve addition and subtraction problems. 7 3 = . find 7 on the number line. the plus sign ( ) means to add more, so count forward 3 units. the answer is 10. First, mark the 12 on the number line. then jump 8 numbers to the right. this is like counting on 8 numbers. the last number you land on is 20. so, 12 8 = 20. you can add bigger numbers in parts by skip counting. find 20 24. start at 20 on the number line. one way to jump 24 is to jump 10 and 10 and 4.

The first step is to locate the first number which is 2on the number line. adding 4 means we have to move the point, 4units to the right. after doing so, we end up at 6. therefore, 2 4 = 6. example 2: simplify by adding the numbers, 3 (–5). locate the first point, 3, on the number line. Observing the above number line models, we can conclude three things: start with one addend. draw as many hops as the other addend. land at the sum. thus, we can easily figure out any missing addend by simply counting the hops or with the start point. let’s take this model for instance and complete the addition sentence: 6 = 11.
