To write a number sentence in 1st grade, you show a math problem using numbers and symbols like +, -, and =.
Steps to Writing a Number Sentence:
- Understand the Problem: Listen to or read the math problem carefully. What is happening? Are you adding things together, taking things away, or comparing numbers?
- Identify the Numbers: Find the important numbers in the problem.
- Choose the Right Symbol:
- Plus Sign (+): Use this for adding things together. For example, "two plus three" means 2 + 3.
- Minus Sign (-): Use this for taking things away. For example, "five minus one" means 5 - 1.
- Equals Sign (=): This means "is the same as." It shows the answer to the problem.
- Write the Sentence: Put the numbers and symbols in the correct order. For example:
- To show "two plus three equals five," you would write: 2 + 3 = 5
- Solve the Problem (if needed): Sometimes you need to find the answer after writing the number sentence.
Examples:
- Problem: "There are 2 apples and 3 oranges. How many fruits are there in all?"
- Number Sentence: 2 + 3 = 5
- Problem: "You have 5 cookies and eat 1. How many cookies are left?"
- Number Sentence: 5 - 1 = 4
Tips for Success:
- Read the problem carefully.
- Practice writing different number sentences.
- Ask for help if you get stuck.
