Show the problem 34,650 - 3,116. Explain that you first subtract the thousands numbers, then the hundreds numbers, tens numbers and ones values. You start to the right of the number line, at 34,650. There, 3,000 is first subtracted, then, you come to 31,650. Next you take away 100, then 10 and finally 6 to reach the answer. After this, show the students the problem 78,748 - 41,627 and have them solve the intermediate steps on their own and fill them in on the lines. Then you show the problem 49,135 - 7,982 and ask the students how they would solve it. Then show the solving strategies used by the children on the whiteboard. Have the students solve the next few problems on their own.

Check whether the students can subtract to 100,000 by asking the following question:

- Which method do you use to solve this problem in steps? (69,485 - 45,122 = ... )
