Walk into any elementary classroom where kids actually get math, and you'll see it. It’s usually a slightly crinkled piece of chart paper taped to the wall, covered in bright markers and maybe a few sticky notes. We're talking about the addition strategy anchor chart. It isn't just decoration. Honestly, it’s the difference between a kid staring blankly at a page of numbers and a kid who says, "Oh, I'll just use the 'make a ten' trick for this one."
Most people think math is just about memorizing facts. You know, flashcards until your eyes bleed. But modern pedagogy—the stuff experts like Jo Boaler from Stanford talk about—emphasizes "number sense." This is basically the ability to play with numbers like they’re LEGO bricks. An addition strategy anchor chart acts as the visual blueprint for that play. It’s a reference point. When a student's brain freezes mid-calculation, they glance at the wall. They find their footing. It builds confidence. It’s a safety net that eventually turns into a springboard.
The Mental Shift: Why Strategies Trump Memorization
If you grew up in the 80s or 90s, you probably learned the "standard algorithm" first. You lined up the numbers, carried the one, and didn't ask questions. But research from the National Council of Teachers of Mathematics (NCTM) suggests that jumping straight to the algorithm can actually stunt a child's mathematical reasoning. They become "procedure followers" instead of "problem solvers."
Using an addition strategy anchor chart forces a different perspective. It shows that there isn't just one way to find a sum. There are dozens. Kids learn that $8 + 7$ isn't just 15 because the card said so; it's 15 because $7 + 7$ is 14, and one more makes 15. Or because you can take two from the seven, give it to the eight to make a ten, and then add the remaining five. This is "composing and decomposing" numbers. It's high-level thinking disguised as a colorful poster.
What Actually Goes on the Chart?
You can't just throw everything at the wall. That’s overwhelming. A good addition strategy anchor chart needs to be curated. It’s a living document. Most teachers start with the basics and add strategies as the class masters them.
The "Count On" Method
This is usually the entry point. You start with the bigger number and "count on" the smaller one. If the problem is $9 + 3$, the kid puts 9 in their head and touches their fingers: "10, 11, 12." Simple. Effective for small numbers. But it gets clunky fast. You don't want a kid trying to count on 47 fingers.

Making a Ten
This is the holy grail of early math. Our entire number system is base-ten. If a student can "make a ten," they can do almost anything. On the chart, this usually looks like a ten-frame visual. For $8 + 5$, you show how 2 moves from the 5 over to the 8. Now you have $10 + 3$. Boom. 13. It’s fast. It’s elegant. It works for $88 + 5$, too.
Doubles and Near Doubles
Kids love doubles. $6 + 6$, $7 + 7$, $8 + 8$. They stick in the brain easily. An addition strategy anchor chart uses these as "anchors" (pun intended). If a kid knows $6 + 6 = 12$, then $6 + 7$ is just one more. We call these "Doubles Plus One." Sometimes "Doubles Minus One." It’s about using what you know to solve what you don’t.
Compensation
This one is for the kids who like to "tinker." If you have $19 + 7$, you just pretend it’s $20 + 7$. That’s 27. Then you take away the one you added. 26. It’s sort of like getting change at a store. It feels like a shortcut, and kids love shortcuts.
Designing for the Human Eye (and Brain)
A messy chart is a useless chart. You’ve seen them—too many colors, tiny handwriting, crowded edges. An effective addition strategy anchor chart needs white space. It needs "breathing room."
Use high-contrast colors. Maybe all the "Double" strategies are in blue and the "Ten" strategies are in red. Use icons. A picture of a head with a number in it for "Counting On." A picture of a bridge for "Bridge to Ten."

One big mistake? Making the chart for the kids instead of with them. If you buy a pre-printed poster from a teacher supply store, it’s just wallpaper. The kids didn’t see it being built. They have no "blood equity" in it. But if you sit on the rug and say, "Hey, how did you solve that? Oh, you split the numbers? Let’s call that the Break Apart strategy and put it on our chart," they own it. They’ll actually use it because it’s their idea.
Real-World Examples of Strategy in Action
Let's look at a multi-digit problem: $45 + 37$.
Without a strategy, a second grader might struggle with regrouping.
But with a solid addition strategy anchor chart to guide them, they have options:
- Place Value Break Apart: $40 + 30 = 70$ and $5 + 7 = 12$. Then $70 + 12 = 82$.
- The Number Line: Start at 45, jump 30 to get to 75, then jump 7 to get to 82.
- Compensation: $45 + 40 = 85$, then subtract the 3 we added to the 37. $85 - 3 = 82$.
See? No "carrying the one" required yet. They’re actually thinking about the value of the digits. This is exactly what the Common Core State Standards (love them or hate them) were trying to get at. It’s about flexibility.
Common Misconceptions About Anchor Charts
People think anchor charts are just for "struggling" students. Wrong. Even high-flyers benefit from seeing multiple pathways. It prevents them from getting stuck in a "one-way" mindset.
Another myth: "They’ll become dependent on it."
In reality, the opposite happens. The more they look at the addition strategy anchor chart, the more those visuals get seared into their long-term memory. Eventually, they stop looking at the wall. The chart has moved from the paper to their brain. That’s the "anchor" doing its job—holding the concept in place until it takes root.

Troubleshooting Your Chart
If your kids aren't using the chart, it’s probably too far away or too complicated.
Try these fixes:
- The "Desk-Sized" Version: Take a photo of the big chart and tape small copies to their desks.
- Interactive Elements: Use Velcro. Let kids move strategy names around or add their own examples of how they used a specific method that day.
- The "Strategy of the Week": Highlight one specific section of the addition strategy anchor chart with a bright "Spotlight" arrow. Focus all your warm-up problems on that one method.
Actionable Steps for Implementation
Creating an effective environment isn't about being an artist. It's about being a facilitator.
First, look at your current curriculum. Identify the three most common strategies it pushes. Usually, it’s "Count On," "Make a Ten," and "Use Place Value." Start your chart with just those three. Don't crowd it.
Second, use real student work on the chart. If Sarah solves a problem using a "Number Line," ask if you can tape her scratch paper directly onto the addition strategy anchor chart. This provides a "mentor text" for other students. It proves that these strategies aren't just things teachers talk about—they're things kids actually do.
Third, keep it updated. If you’re moving into three-digit addition, the "Count On" strategy might need to be retired or moved to the "Old Tools" section. It's okay to retire strategies that are no longer efficient. This teaches kids about growth and choosing the right tool for the job.
Finally, refer to it constantly. If a student asks for help, don't give them the answer. Point to the chart. Ask, "Which one of our tools feels right for these numbers?" This shifts the teacher from "Giver of Knowledge" to "Coach." That’s where the real magic happens in a math classroom.
