Do animated visual explanations help kids understand math better? A teacher’s real perspective
Last Tuesday, I stayed late to help my 4th grade student Mia work through equivalent fractions, the same concept she’d stumbled on three times that week. Eraser smudges blurred half the answers on her worksheet, her neon pink backpack had slipped halfway off the side of my desk, and the fluorescent lights hummed loud enough to drown out the soccer practice going on outside the gym windows. Mia kept insisting 3/6 was bigger than 1/2, because 3 is bigger than 1, and 6 is bigger than 2. I’d pulled out my paper fraction circles, lined them up, pointed out how they matched. She nodded, then got the next problem wrong anyway.
On a whim, I pulled up the animated fraction explanation from our new math curriculum, the one the sales rep insisted would fix all our abstract math gaps. The animation started with a whole pizza, then slowly cut it into two equal slices, one of which lit up to show 1/2. Then it cut the same pizza into six equal slices, and slid three of them over the top of the 1/2 slice, pixel by pixel, until they fit exactly. Mia leaned forward, her elbow knocking my half-eaten granola bar an inch to the left, and said, “Oh. Wait. They’re the same size? I just didn’t see how they split before.” That moment got me thinking again about the big question everyone’s been asking since we adopted the new program: do these things actually work?
Then I think of Javi, another 4th grader in my class, who struggles with focus and loves anything he can touch with his hands. Two weeks after Mia’s after-school session, we were working on finding the area of irregular shapes. The curriculum’s animation splits the shape into two simple rectangles, moves them apart so you can calculate each area, then adds them back together. I played it for Javi, and he blinked at the screen, his foot tapping faster and faster under the desk. “Where did the extra line go?” he asked me after it finished. “I don’t get how it was one shape and now it’s two.” I turned the screen off, handed him a pair of safety scissors and a printed copy of the shape, and told him to cut it apart himself. Two minutes later, he’d measured both pieces, added the areas, and moved on to the next problem without another question.
Our school rolled out this full curriculum of animated explanations last fall, after data showed our kids were scoring below average on state math tests. The sales pitch was that animations turn abstract concepts into something kids can see happen, instead of just seeing a static drawing on a page. I’ve been jotting down notes on every lesson I use them for, so after six months I have a pretty good idea of what works and what doesn’t.
The big thing I’ve noticed is that animations work best when they show a change that’s hard to picture from a static drawing. If you’re teaching equivalent fractions, or how a number line moves when you add negative numbers, or how perimeter changes when you stretch a rectangle, showing that change step by step helps kids who can’t easily imagine that movement in their head. It’s not that these kids are worse at math—it’s that mental visualization takes time to develop, and some kids need to see it happen before they can do it on their own.
But when animations have too much going on, or when a kid needs to interact with the concept instead of just watch it, they fall flat. My own 8-year-old son found a math animation on YouTube last month to help him with multiplication, and it had bouncing numbers, a dancing monkey, and silly sound effects every time a new number popped up. He watched the whole thing laughing at the monkey, and couldn’t tell me what 3 times 4 was when it was over. When I found a slower animation with no frills that just added one group of 3 at a time, counting each out loud as it went, he got it on the first watch.
From what I’ve talked about with our school’s learning specialist, this lines up with what research shows, too. Too much extra movement or decoration pulls focus from the actual math concept. And for kids who need tactile input to learn, watching a screen move is never going to be as good as moving something with their own two hands.
The good news is you don’t have to throw out all the animations you’re using—you just have to use them the right way. I’ve started doing a few small things that make a huge difference, any parent or teacher can do them too. First, I always turn off any extra sound effects or flashy backgrounds before I show an animation to a kid. Most free and paid math platforms let you adjust these settings in two clicks. Second, I never let an animation play straight through. I pause after every single step, and ask the kid what they think will happen next before I hit play again. That keeps them engaged instead of just passive watching. Third, if they’re still confused after two slow run-throughs, I turn it off immediately. I swap it for whatever physical version we can pull together: cut paper shapes, cereal pieces for counting fractions, even drawing each step out by hand on a piece of paper.
I still use animated explanations three or four times a week in my class. They’re great for introducing new concepts, and they give kids a different way to see something that just isn’t clicking with pencil and paper. But I don’t expect them to fix all our math problems, and I don’t force a kid to sit through an animation that’s not working for them. Last week, Mia got a B+ on her fractions test, and Javi turned in a whole set of area problems with all the shapes he’d cut out taped to the back. Both got most of the answers right, just using the tool that worked for them. I don’t think there’s ever a one-size-fits-all answer to what helps kids learn math, but animations can be really helpful—when you use them right.
