Free Make Ten and Doubles Strategy Games for K–3
These three free math games are designed to help students in Kindergarten through Grade 3 move beyond counting strategies and toward genuine addition fact fluency. Each game targets a specific strategy — bridging to ten using ten frames, building doubles facts, and using known doubles to solve near-doubles problems. All three work on a smartboard, laptop, or at a math center. No login, no download, and no prep required.
Make Ten Strategy Game — Free Addition Game for K–2
About the Game
The Make Ten strategy is a widely used mental math approach that helps students develop fluency with addition within 20. Instead of counting each object individually, students break apart one number in order to bridge to ten. For example, when solving 8 + 6, a student moves 2 from the 6 to the 8 to make 10, leaving 4, resulting in 10 + 4 = 14. This game makes that process visible and interactive using two ten frames and moveable counters.
How It Works
Students place counters on two ten frames and then slide counters from one frame to another to complete a group of ten. This concrete, hands-on experience helps students understand that the total quantity does not change even though the numbers are being reorganized — a foundational insight that supports all future work with addition strategies and place value.
Over time, repeated practice with these visual models helps students internalize number relationships and perform addition mentally without needing the physical counters. The game is free, requires no login, and works on any smartboard, tablet, or classroom computer.

The Research Behind Make Ten
Research and classroom practice consistently show that using visual tools such as ten frames and counters helps students build strong mental images of number relationships and understand how numbers can be decomposed and recombined. Because our place value system is built around groups of ten, developing this understanding early supports later work with larger numbers, place value, and multi-digit addition.
Ten frames are especially powerful because they allow students to see and physically move quantities. Research on the Make Ten strategy confirms it is one of the most effective mental math approaches for building addition fluency within 20 — and that students who develop this strategy early are better equipped for the demands of multi-digit arithmetic later on.
The Make Ten strategy is one of the core addition strategies assessed in the Primary Numeracy Intervention Program, a free K–3 math intervention built on the same research foundation as this game. If this activity is revealing gaps in your students' addition strategy development, the program gives you a precise diagnostic tool to identify exactly where the breakdown occurs and leveled materials to address it systematically — all free after completing a two-hour training.
Doubles Facts Game — Free Addition Game for K–3
About the Game
Doubles facts are among the most important building blocks of addition fluency. When a student knows that 6 + 6 = 12 without having to count, they have a reliable anchor they can use to solve a whole range of related problems quickly and efficiently. This free interactive game is designed to help students in Kindergarten through Grade 3 build confident, automatic recall of doubles facts from 1 + 1 all the way through 10 + 10.
How It Works
The game presents doubles problems one at a time and asks students to identify the total. Visual supports help students see the doubling relationship clearly — two equal groups that can be recognized and remembered as a unit rather than calculated from scratch each time. Each round includes immediate feedback so students know right away whether their answer was correct, and the game keeps a running score to maintain engagement and motivation.
Use this game on a smartboard for whole class practice, at a computer station for independent work, or as a quick warm-up at the start of a math lesson. No login, no download, no prep required.

The Research Behind Doubles Facts
Doubles facts are widely recognized in mathematics education research as one of the first sets of addition facts students should be taught to automaticity. Because both addends are identical, doubles are easier to visualize and remember than other addition facts — making them a natural starting point for building fact fluency.
The National Council of Teachers of Mathematics emphasizes that fact fluency should be built through strategic thinking and pattern recognition rather than rote memorization alone — and doubles facts are one of the clearest examples of a fact set where visual patterns and structural reasoning make memorization natural and meaningful.
Doubles facts and addition fact fluency are among the core skills assessed in the Primary Numeracy Intervention Program, a free K–3 math intervention built on the same research foundation as this game. If this activity is revealing gaps in your students' fact fluency development, the program gives you a precise diagnostic tool to identify exactly where the breakdown occurs and leveled materials to address it systematically — all free after completing a two-hour training.
Doubles Plus or Minus One — Free Near-Doubles Strategy Game
About the Game
Once students know their doubles facts, they have a powerful tool for solving a whole range of nearby problems. The Doubles Plus or Minus One strategy teaches students to look at a problem like 6 + 7 and think — I know 6 + 6 = 12, so 6 + 7 must be one more, which is 13. Instead of counting up from scratch, students use a fact they already know as a stepping stone to derive the answer. This free interactive game is designed to build that strategy in students from Kindergarten through Grade 3.
How It Works
The game presents near-doubles problems and supports students in recognizing the relationship between the problem in front of them and the doubles fact they already know. Students identify whether the problem is one more or one less than a doubles fact, use that known fact as their anchor, and adjust by one to find the answer. Each round includes immediate feedback, and the game keeps a running score to maintain engagement.
This game works on a smartboard for whole class instruction, at a computer station for independent practice, or as a targeted activity for small group intervention. No login, no download, no prep required.
Why Near-Doubles Matter
The Doubles Plus or Minus One strategy is significant because it represents a fundamental shift in how students think about addition. Rather than treating every problem as a new calculation to be figured out from scratch, students begin to see relationships between facts — using what they know to figure out what they do not know. This is the foundation of flexible mathematical thinking and is far more powerful than memorization alone.
Near-doubles problems — facts like 3 + 4, 5 + 6, and 7 + 8 — account for a significant portion of the single-digit addition facts students need to master. A student who can use the doubles plus or minus one strategy has an efficient, reliable method for solving all of these problems without counting, dramatically reducing the cognitive load of early arithmetic.

The Research Behind Doubles Plus or Minus One
Research on how children develop addition fact fluency consistently identifies derived fact strategies — strategies where students use a known fact to figure out an unknown one — as a critical bridge between counting strategies and full automaticity. The near-doubles strategy is one of the most well-documented examples of this, and it is widely recommended in mathematics education research as an explicit instructional target in Grades 1 through 3.
Studies on arithmetic strategy development show that students who are explicitly taught derived fact strategies like near-doubles outperform students who rely on counting or rote memorization alone — both in speed and in their ability to transfer their knowledge to new and unfamiliar problems.
The National Council of Teachers of Mathematics emphasizes that building fact fluency through strategic reasoning — rather than drill alone — leads to deeper understanding and more durable learning. The near-doubles strategy is one of the clearest examples of how strategic thinking and fact knowledge reinforce each other.
Near-doubles and derived fact strategies are among the core addition strategies assessed in the Primary Numeracy Intervention Program, a free K–3 math intervention built on the same research foundation as this game. If this activity is revealing gaps in your students' strategy development or fact fluency, the program gives you a precise diagnostic tool to identify exactly where the breakdown occurs and leveled materials to address it systematically — all free after completing a two-hour training.
