Explain that to solve the problem 8,000 - 1,949 you first subtract the thousands numbers, then the hundreds numbers, tens numbers, and ones values. Then discuss the problem 2,000 - 1,090 together. Show how the children solve the problem and ask the students how they would solve it. Next, have the students solve the next few problems on their own. Explain that for a story problem you must first determine what type of problem it is. Then you see what numbers you need from the story, and you state the problem. The last step is solving the problem. You can do this for example by first doing 2,000 - 1,000 and then 1,000 - 100. Discuss the problem with the animal images together and have the students solve the next problem on their own.

Check whether the students can subtract from a thousands number by asking the following question:

- Which method do you use to solve this problem in steps? (3,000 - 1,011 = )
