Addition: Combining two or more groups of objects to find the total amount
Counting: Moving one by one through each object while saying numbers
- Count all objects in the first group
- Count all objects in the second group
- Combine both groups and count the total
- Write the addition sentence
Group 1 has 3 apples: πππ = 3
Group 2 has 2 apples: ππ = 2
Total: πππ + ππ = πππππ = 5
3 + 2 = 5
There are 5 apples in total
β’ Counting: Count each object once and say the number out loud
β’ Combining: Put both groups together to find the total
β’ Writing: Use the + sign for addition and = for equals
Grouping: Putting different types of objects together in one collection
Total: The final amount when all groups are combined
Bananas: ππ = 2
Oranges: πππ = 3
Total fruits: 2 + 3 = 5
Count all: πππππ = 5 β
There are 5 fruits in total
β’ Different objects: Can still be added together in the same total
β’ Grouping: Different types of objects form one combined group
β’ Verification: Always count the total to check your answer
Number Bond: Shows how a number can be split into parts
Parts and Whole: Smaller numbers that combine to make a larger number
We want to make 5 (the whole)
One part is 2
Count up from 2 to 5: 2, 3, 4, 5
We counted 3 more numbers, so the missing part is 3
2 + 3 = 5 β
2 + 3 = 5, so the missing number is 3
β’ Number bonds: Help understand how numbers break apart
β’ Counting up: Start with the known part and count to the whole
β’ Verification: Check that the parts add up to the whole
Addition: Combining groups to find the total amount
Sum: The answer when adding numbers together
Plus Sign (+): Symbol for addition operation
- Identify groups: See separate collections of objects
- Count each group: Determine how many in each group
- Combine groups: Put all objects together
- Count total: Find the sum of all objects
- Write equation: Use numbers and symbols
β’ Counting rule: Each object gets counted exactly once
β’ Order doesn't matter: 2 + 3 = 3 + 2
β’ Adding zero: Any number + 0 = same number
β’ Equals means same: Both sides represent the same amount
Word Problem: A math question written in story form
Keywords: Words that tell us what operation to use ("more", "total", "altogether")
Sarah starts with 4 carrots
She gets 3 more carrots
Total carrots Sarah has now
Start with + More = Total
4 + 3 = ?
Count all carrots: π₯π₯π₯π₯ + π₯π₯π₯ = π₯π₯π₯π₯π₯π₯π₯
That's 7 carrots total
Sarah has 7 carrots now
β’ Story understanding: Find the important numbers
β’ Keyword identification: "More" means addition
β’ Picture drawing: Visualize the problem
Mixed Addition: Adding groups of different types of objects
Total Count: Finding the sum regardless of object type
ππ = 2 strawberries
π«π«π« = 3 blueberries
π = 1 lemon
2 + 3 + 1 = 6 total fruits
Count all: πππ«π«π«π = 6 β
There are 6 fruits in total
β’ Multiple groups: Can add more than two groups together
β’ Different types: Different objects still add up to a total
β’ Sequential addition: Add groups one at a time
Addition: The process of combining two or more quantities to find a total
Objects: Physical items used to represent numbers (apples, blocks, etc.)
Pictures: Visual representations of numbers and operations
- Visual Recognition: Identify and count objects in each group
- Grouping Strategy: Mentally or physically combine the groups
- Sequential Counting: Count all objects in the combined group
- Symbols Translation: Convert to numerical equation
β’ Counting sequence: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, ...
β’ Addition equation: Part + Part = Whole
β’ Commutative property: a + b = b + a
β’ Identity property: n + 0 = n
