Study Notes
Addition Strategies
-
Counting On: Start with the first number, then count on the second number to find the total.
- Example: 2 + 3 = Start with 2, count on 3 more: 2, 3, 4, 5
-
Making Ten: Find the sum by making a ten with one or both numbers.
- Example: 8 + 2 = 8 + 2 = 10
-
Using Number Lines: Move along a number line to find the sum.
- Example: 5 + 4 = Move 5 units, then 4 more units to find the total: 9
Word Problems
- Reading and Understanding: Read the problem, identify the numbers, and determine the action (addition).
- Acting Out: Use objects or drawings to represent the problem and find the solution.
- Key Words: Look for words like "altogether", "in total", "how many" to indicate addition.
- Real-World Applications: Use everyday scenarios to practice addition, such as counting toys or blocks.
Counting On
- Definition: A strategy for adding numbers by starting with the first number and counting on the second number.
