Hi there! I am Studyfin. Let's learn how to solve any big problem step by step!
When you see a big problem, do not worry. You can use a special plan to solve it. First, you must read and find the clues.
Next, you make a plan. You think about what tools or math to use. Then, you find your answer.
Last, you check your work. Does your answer make sense? Checking your work helps you learn and stay correct.
✏️ Worked example
Leo has 12 red blocks. He has 8 blue blocks. He gives 5 blocks to his sister. How many blocks does Leo have left?
- Analyze: We know Leo has 12 red blocks and 8 blue blocks. He gives away 5 blocks.
- Plan: First, add the blocks to find the total. Then, subtract the blocks he gave away.
- Solve: Add 12 and 8 to get 20. Next, subtract 5 from 20 to get 15.
- Justify: We can check by adding back. 15 blocks left plus 5 given away equals 20. It works!
- Evaluate: The steps were clear. Starting with 20 blocks and ending with 15 makes sense.
