Study Notes
Basic Addition and Subtraction
Numbers and Operations
- Addition: combining two or more numbers to get a total or a sum
- Subtraction: finding the difference between two numbers
Key Concepts
- Counting On: starting with one number and counting on to find the total (e.g., 3 + 2 = 3, 4, 5)
- Counting Back: starting with one number and counting back to find the difference (e.g., 5 - 2 = 5, 4, 3)
- Making Ten: using the number 10 as a reference point to make calculations easier (e.g., 8 + 2 = 10, 9 + 1 = 10)
Basic Addition Facts
- Single-Digit Addition: adding single-digit numbers (e.g., 2 + 3 = 5)
- Doubles: adding the same number to itself (e.g., 2 + 2 = 4)
- Near Doubles: adding a number to itself plus or minus one (e.g., 2 + 3 = 5, 3 + 2 = 5)
Basic Subtraction Facts
- Single-Digit Subtraction: subtracting single-digit numbers (e.g., 5 - 2 = 3)
- Counting Back: starting with one number and counting back to find the difference (e.g., 5 - 2 = 5, 4, 3)
- Missing Addend: finding the missing number in a subtraction problem (e.g., 5 - ___ = 3)
Strategies for Basic Addition and Subtraction
- Using Number Lines: visualizing numbers on a number line to help with calculations
- Using Real-World Objects: using real-world objects to represent numbers and make calculations more concrete
- Making Connections: connecting new math concepts to previous learning and real-world experiences
