Operations in First Grade Math

Addition

First graders learn about addition, which is the process of combining two or more numbers to find a total. They practice counting on, using number lines, and understanding the concept of addition as putting together or combining two or more sets.

Subtraction

Subtraction is the process of taking away one number from another. First graders learn about subtraction through counting back, using number lines, and understanding the concept of subtraction as taking away or finding the difference between two numbers.

Understanding Symbols

First graders also learn about the symbols used in operations, such as the plus (+) and minus (-) signs. They practice recognizing and using these symbols in addition and subtraction problems.

Practice Activities

Here are some activities to help first graders practice operations:

• Using manipulatives such as counting blocks or toys to act out addition and subtraction problems.
• Practicing addition and subtraction with flashcards or online math games.
• Using real-life scenarios to create and solve addition and subtraction problems, such as counting objects or sharing items with friends.
