Do Animated Visual Explanations Help Kids Understand Math Better? A Classroom Teacher’s Experience
It was 9:17 a.m. on a Tuesday, and I was walking between desks during my 4th grade fractions block when I stopped next to Mia. Her scuffed white sneakers were propped against the leg of her desk, a half-eaten strawberry lollipop stuck out of the front pocket of her gray hoodie, and she was leaning so far into her Chromebook I thought she’d fall over. For three weeks, we’d been working on equivalent fractions, and Mia had asked me at least four times a day why multiplying the top and bottom by the same number didn’t change the value. “Ms. Henderson, look,” she said, pulling me over without looking up. The screen showed an animation: a whole pizza cut into two slices, one shaded. Then the animation slowly split each slice in half again, counting the new slices one by one, the shaded area stretching just enough to cover two of the new four total slices. “It’s still the same amount of pizza,” she said, turning to me like I’d just revealed a secret stashed in my desk. “I get it now.”
I’d split the class into two groups for this unit, on a lark. The district had just rolled out a new math tool full of animated explanations for every core concept, and I was curious. Half my class stuck with my usual routine: paper circle cutouts, my messy whiteboard drawings, partner practice with worksheets. The other half used the animated explanations for their independent work, before moving on to practice problems. I didn’t expect much at first—I’d seen plenty of fancy ed tech tools that just kept kids busy instead of actually teaching them anything.
Over the two weeks of the experiment, I started noticing small shifts. Javi, who usually maxes out at 8 minutes of independent work before he’s drawing dinosaurs on his notebook, replayed the animation for dividing a chocolate bar three times just because he wanted to check if all the new pieces were the same size. He stayed focused for 15 minutes, no reminders, which is a win for him. A lot of the kids who struggled with memorizing steps started asking different questions. Instead of “what do I do next?”, they asked “why does that work?” That’s the question I’ve always wanted them to ask, honestly.
It wasn’t all good, though. Halfway through the unit, I gave a low-stakes quiz on paper, no screens, and three of the kids in the animation group stared at their pages for five minutes before raising their hands. They couldn’t draw an equivalent fraction for 1/3 on their own. One of them said, “I can’t remember how the animation did it, so I don’t know how to do it.” Lila, who picks up math concepts faster than almost anyone else in the class, was clicking through animations as fast as she could just to get to the quiz, not paying any attention to the explanation. She told me after, “It goes too slow. I already know it, why do I have to watch it?”
I talked about this with our school math coach over lunch that week, and she put what I was seeing into words. A lot of math concepts are about change over time—splitting things, moving decimals, rearranging shapes to find area. When you draw two static fractions next to each other on a whiteboard, some kids don’t connect how you got from the first one to the second. The animation shows that step by step, so they can see the relationship instead of just being told it exists. That’s why it clicked for Mia, who couldn’t wrap her head around why the value didn’t change when you multiply the numerator and denominator. She could see the shaded area didn’t get bigger or smaller, just split into more pieces.
That doesn’t mean animations are better than the old tools, though. The problem comes when you use them as a replacement instead of a bridge. What I’ve started doing now, that’s worked really well, is this: If I’m working with a kid who’s stuck, I pull up the animated explanation once, let them watch it, then I ask them to do the same thing right after with a pencil and paper, or a manipulative like a measuring cup or a candy bar. It doesn’t take any extra time, really, just an extra two minutes.
For parents who are helping with homework at night, the same approach works. If you’ve explained a concept three times and your kid still doesn’t get it, pull up a short animated explanation on YouTube or a free math site, watch it together, then ask them to show you how it works with things you have around the house—pizza slices, crackers, pieces of cereal, whatever. If your kid gets distracted by all the flashy extra bits most animations have, just turn the sound off and pause it after each step to talk about what’s happening. And if your kid already gets it, don’t make them sit through the animation. Let them skip it and go practice.
Last week, Mia’s mom emailed me. Mia had pulled up the equivalent fraction animation on her home tablet to explain it to her 6-year-old little sister, then drew two circles on a piece of construction paper to show her the same thing. That transfer worked, because she didn’t just watch the animation—she recreated it herself.
I still don’t think there’s one answer that works for every kid, or every concept. Just last week I had a boy who didn’t get adding fractions with unlike denominators after watching three different animations, so we got out measuring cups and water at the back of the classroom, and he got it after two tries. Animations aren’t magic. They don’t make hard math easy for everyone, all the time. But they’re a really useful extra tool to have around. When you’ve tried the same old explanation a few times and it’s not sticking, it’s just another way to show kids what’s actually happening, instead of just asking them to memorize it. I’m still mixing it up, still testing what works for each kid, and I think that’s all any of us can do.
