Addition Games and Worksheets

Online Addition Games

Welcome to the Addition Games hub! Whether you are a young learner just starting to count objects or a math pro tackling four-digit challenges, our platform turns arithmetic practice into an engaging journey.
Addition is the cornerstone of all mathematics. By mastering these games, you develop the “number sense” needed for real-world problem solving and advanced algebra.

Picture Math
Visual Addition: Count and add objects.
Part-Whole Model: Number Bonds within 10 using Part-Whole Model.
Repeated Addition Repeated addition for equal groups.
Addition Sentence Addition sentence for equal groups.

Mental Addition & Strategic Thinking
Learn to add in your head. These games focus on visualization and efficiency.
Number Bond Garden: Learn the number bonds to ten by selecting the orbs and clearing the board.
Friends of Ten: Master the pairs that make 10 (like 7+3) to build a rock-solid foundation. Use Ten Frames to visualize numbers as physical spaces to understand how they combine.
Make a Ten to Add: Learn to “bridge” to the next ten. For example, solve 8 + 5 by thinking (8 + 2) + 3. Sum up to 20.
Addition using Make a Ten: Extend learn to “bridge” to the next ten for bigger numbers. For example, solve 37 + 9 by thinking (37 + 3) + 6. Sum > 20.
Doubles & Near Doubles: Use the power of 6 + 6 to quickly solve 6 + 7.
Add to the Next Ten: Practice “filling up” the number line (e.g., ? + 6 = 80).
Add Whole Tens to a Number: Master adding whole tens to any number, from simple 20 + 70 to complex challenges like 30 + 682.
Add Multiples of 10: Practice adding whole tens (e.g., 20+70).

Relating Addition & Subtraction
Addition and subtraction are inverse operations. Understanding this is the secret to solving math problems faster and checking your work. Our games are designed to help you visualize these connections.
Number Bonds: Choose which number bond to make.
Fact Families: Discover the deep link between addition, subtraction, multiplication, and division.
Penguin Addition/Subtraction: A fun, themed way to practice addition and subtraction. Help the baby penguin find its mummy. Match the baby penguin to the correct adult penguin.
One More, One Less: Can you identify the neighbors of any number up to 999?
Number Sentences to 10 (Addition & Subtraction to 10)
Operator Detective (Which operator is missing?)
Balance Game (4+6 = 7+?)

Master the Horizontal Addition Equation
While column addition is great for big numbers, Horizontal Addition—written from left to right like a sentence—is the key to developing mental math fluency and algebraic thinking.
Understand the Equal Sign: Count objects to prove both sides are equal.
Add Objects: The perfect starting point! Count the items, write the corresponding numbers, and find the total.
Build 2-digit Numbers: Master place value by assembling numbers from their parts (e.g., 20 + 5 = ? or ? + 7 = 87).
Fixed Addend: Want to master your “+7s”? Lock in a number and practice.
Missing Addends: Find the missing addends (e.g., 9 + ? = 20 or ? + 3 = 12).

1-digit Addition
1-digit addition involves adding numbers from 0 to 9. The goal here is fluency—learning to recognize sums instantly without needing to count on your fingers.
1-Digit Addition (5+7=?)
Add 3 numbers using Make Ten Strategy
Add 3 to 5 single digits

Multi-Digit Addition
Once you know your basic facts, it’s time to proceed to multi-digit addition without regrouping and then with regrouping.
Multi-Digit Addition (with no regrouping)
2-Digit + 1-Digit
2-Digit + 2-Digit
Multi-Digit Addition (with regrouping)
Addition (Choose maximum sum)
2-Digit + 1-Digit
3-Digit + 1-Digit
2-Digit + 2-Digit
3-Digit Addition
4-Digit Addition

Column Addition (Vertical Format)
When you move from simple mental math to larger numbers, Column Addition (also known as the Vertical Format) becomes your most powerful tool. By stacking numbers on top of each other, you can break down complex problems into small, manageable steps.
1-digit + 1-digit Column Addition
2-digit + 1-digit Column Addition
2-digit + 2-digit Column Addition
3-digit + 2-digit Column Addition
3-digit + 3-digit Column Addition
4-digit + 4-digit Column Addition
Multi-Addend Challenge

Addition/Subtraction Word Problems
Word problems are like puzzles—they give you a story, and you need to figure out which mathematical “tool” (addition or subtraction) will solve the problem.
Addition/Subtraction Word Problems: 1st Grade Adventures: Simple one-step stories using small numbers.
Addition/Subtraction Word Problems: (2nd Grade): Slightly more complex stories that might require regrouping or larger numbers.
Word Problems (Change Unknown)
Word Problems (Start Unknown)
2-Step Addition/Subtraction Word Problems: These stories have a “hidden” step. You might need to add first, then subtract to find the final answer.
Comparison Word Problems: These are tricky! They ask you to find the “gap” between two people or things.
