Making Subitizing Count

Subitizing Helps With Fluency

Developing fluency is one of the most talked-about areas in math. OMG, do we talk about it? Whew! There are a billion strategies out there- some good, some not so good. Some strategies are researched-based, and some are passed along from teaching generation. Number Talk books

What no one can argue is that subitizing plays a vital role in developing fluency?
One definition of fluency is knowing how a number can be composed and decomposed. Subitizing is just that.

So What Is Subitizing Exactly?

Subitizing is instantly seeing how many. Recognizing a collection of objects as one unit. There are two forms of subitizing:

The first form is the Perceptual Subitizing.
This is the simplest form of subitizing. Studies have found that even animals and infants do it. This form of subitizing is the ability to see a couple of objects and immediately know the number. You can see this skill, for example, when you roll a die. After rolling, you immediately know how much without counting the dots one by one. To build this skill, children need a lot of exposure to visual patterns for quantities of three, four, and five. Subitizing Cards

The second form is Conceptual Subitizing.
This is a more advanced skill. It is the ability to see a larger number decomposed. Pictures with more than 5 dots help students with decomposition (break apart). If you were to see a set of 8 dots you might see it as two groups of four, or a group of five and a group of 3. This form of subitizing uses the counting on addition strategy and/or the counting back subtraction strategy. Subitizing App

Progression Of Subitizing

Here’s where we at times, fall short. Not all subitizing is created equal. There is a progression to keep in mind. At times when subitizing doesn’t seem to work for our students, it’s because they are on a different level of progression than you might expect.

Build Subitizing Skills

  1. There are a couple of types of dot images, one color dots or two colored dots. I almost always stick to one color dots. I only expose students to two colored dots when I want students to see specific combinations. Your asking students to see a particular number sentence.
  2. Show them in organized arrangements but also in scattered arrangements.
  3. You don’t have to use dots. It can be any shape or figure. It could also be beads, fingers, a carton of eggs.
  4. Subitizing can eventually help with counting on. Savy Subitizing
  5. Dot card quick flash is a great activity. Ask, “how many did you see? How did you see them? Make it the same using counters on your table.”
  6. Students can make their own subitizing cards using index cards and sticker dots or bingo markers. They have a lot of fun with this activity.
  7. Link to the subitizing cards to number sentences. But in Kinder, a teacher should write down the equations at first. For example:
    3 and 4 is the same as
    3 + 4 is equal to
  8. Don’t forget about the older kids! Number talks provide opportunities to help students develop fluency through subitizing. It is not limited to Kinder and first grade. All grade levels need exposure but in different forms. You’d be surprised to see how early multiplication can start. My own son when shown 6 dots (at three years old) would say he saw two groups of three. Without knowing it of course he was building a multiplication skill. Try the example below with your students. See what they come up with.

Incorporate subitizing into your math routine. These activities could be done in the beginning of your math block, end of your math block, right before walking to special or waiting for dismissal. Multiplication subitizing cards

Math Struggles Ain’t Just About Numbers

Let’s be B.F.F.R—math can stress kids out. You’ve seen it: the frozen-in-place stare, the pencil tapping like it’s sending an SOS, or the classic “I CAN’T DO THIS!” meltdown before even trying. But here’s the thing—most of the time, their struggle isn’t about numbers. It’s about mindset.

What if we borrowed some life coaching techniques to help our students not just survive math but actually thrive in it? Let’s break it down into simple, practical ways you can empower your students without turning into a full-blown therapist.

 Reframe the Narrative (A.K.A. Flip the Script on “I’m Bad at Math”)

Ever notice how kids say “I’m bad at math” like it’s their official personality trait? That belief is holding them back more than any tricky word problem ever could.

How to Do It:

  • When a student says, “I suck at math,” respond with: “You’re still learning. Let’s find a way that makes sense to you.”
  • Introduce the Power of Yet: “You don’t get it… yet. But your brain is working on it!”
  • Share stories of people who struggled with math and overcame it (bonus points if you can find famous athletes, musicians, or influencers).

Remind them that they once thought tying their shoes was impossible, and look at them now—shoe-tying pros. Math is just another skill that takes practice.

Teach Emotional Regulation (Because Frustration Is a Math Blocker)

We can’t expect students to push through challenges if they’re spiraling into math-induced panic mode. When frustration kicks in, their brains hit the “I’m out!” button.

How to Do It:

  • Pause & Breathe: Before jumping to the “I CAN’T,” have students take a deep breath. Try “breathe in for 4, hold for 4, out for 4.” Simple, but it works.
  • Break It Down: Instead of tackling the whole problem at once, ask, “What’s one thing we DO know?” Small wins build confidence.
  • Normalize Struggle: Post a sign in your classroom: “Mistakes Mean You’re Learning.” Say it. Live it. Believe it! As Naruto says.

Set Micro-Goals (Because Big Goals Can Feel Overwhelming)

If a kid already feels lost, telling them “just keep practicing” is like saying, “just climb this mountain real quick.” Instead, break it into steps.

How to Do It:

  • Instead of “Get better at multiplication,” set a goal like: “Practice a doubling/halving strategy.”
  • Use progress charts so students can SEE their growth. 
  • Celebrate the small wins! Even if they only got one more right than last time—that’s growth!

Remind them “If you can memorize every single lyric to that TikTok song, you can 100% remember a few math strategies.” 
Honestly research shows long term memory is activated when we leverage different modalities in our lessons. It’s how the brain learns math.

Shift from Performance to Progress (Because Speed Ain’t Everything)

Fluency is about thinking efficiently, not racing to the answer. The goal isn’t to turn kids into human calculators—it’s to help them use numbers flexibly.

How to Do It:

  • Replace timed tests with strategy-based challenges (ex: “How many ways can you solve 12 × 8?”).
  • Instead of praising fast answers, celebrate smart strategies: “Ooooh, I love how you broke that down!”
  • Remind them that even adults use tools like calculators and sticky notes—real math is about knowing how to approach problems, not just getting the answer instantly.

 Teach Self-Talk (Because Their Inner Voice Matters More Than You Know)

The way kids talk to themselves about math shapes their experience with it. If they constantly say, “I can’t do this,” their brain believes it. Time to switch up the self-talk game.

How to Do It:

  • Teach “I can” statements: Instead of “I don’t get it,” try “I don’t get it YET, but I can figure this out.”
  • Have students write down one math strength (even if it’s “I’m good at counting on my fingers” – that’s a start!).
  • Encourage students to talk to themselves like they’d talk to a friend. Would they tell a friend, “You’re dumb at math”? No? Then don’t say it to yourself either!

Emphasize- “You wouldn’t let your best friend talk trash about you, so don’t let your brain do it either!”

Coaching Math Mindsets for the Win

At the end of the day, teaching math fluency isn’t just about numbers—it’s about helping kids believe they can figure things out. When we shift from just teaching math to coaching their mindset, we create students who are not only fluent in math but confident in life.

So, here’s your challenge: What’s one small move you can try this week? Whether it’s shifting self-talk, celebrating small wins, or breaking down frustration, pick one and run with it.
