让我们一步一步来解决这道题！Sarah开始有24张贴纸。她给了朋友Tom 8张贴纸。我们需要找出Sarah还剩下多少张贴纸。这是一道减法题！
现在让我们分析这道题。首先找出已知条件：Sarah开始有24张贴纸，她给出去8张。问题是还剩下多少张。这需要用减法来解决。让我们用图形来表示这个过程。
现在我们来计算答案。24减8等于16。所以Sarah还剩下16张贴纸。我们可以通过数一数来验证这个答案是否正确。这就是我们解决减法问题的方法！
Now let's understand what this problem is asking. We know Sarah starts with 24 stickers. She gives 8 stickers to her friend Tom. We need to find out how many stickers Sarah has left. This is a subtraction problem because we're taking away some stickers from the total.
Now let's plan how to solve this problem. We look for key words that tell us what operation to use. Words like 'gives away' and 'how many left' tell us this is a subtraction problem. We start with 24, subtract 8, and find our answer. We can also use a number line to visualize jumping back 8 spaces from 24.
Now let's solve this step by step. First, we write our problem: 24 minus 8 equals what? Next, we can count backwards from 24. We count back 8 numbers: 23, 22, 21, 20, 19, 18, 17, 16. So 24 minus 8 equals 16. Let's check our work by adding: 16 plus 8 equals 24. That's correct! Sarah has 16 stickers left.
Now let's check our answer to make sure it's correct. We can add back: 16 plus 8 equals 24. That matches our original amount! We can also use a number line, starting at 16 and counting forward 8 spaces to reach 24. Or we can use real objects: 16 stickers plus 8 more stickers equals 24 total stickers. All methods confirm our answer is right!
