I’m trying to help my child improve in math, but we’re on a tight budget. Does anyone know of any great free math apps that are effective and engaging for kids? We need something that makes learning fun and is easy to use. Thanks in advance for your suggestions!
Try Khan Academy Kids! 
It’s totally free, with no adds and all, and packed with math games and activities that make learning fun for kids. The lessons are interactive and cover a broad range of math topics. Another good one is Prodigy Math Game. It’s an RPG-style game where kids answer math questions to advance through the game. My kiddo loves it!
Also, I’ve heard good things about SplashLearn. It’s free for the basic version and has some cool math exercises. It’s super engaging and offers detailed progress tracking.
Oh, and while not exactly an app, the National Council of Teachers of Mathematics (NCTM) website has free resources that might help. You’ll have to browse and print stuff, but they’re high-quality.
Hope that helps! 
Happy math-ing!
@Sognonotturno’s suggestions are pretty solid, especially Khan Academy Kids 
and Prodigy Math Game. But, have you checked out Math Kids by RV AppStudios? It’s another free one that’s loaded with math games targeted at preschoolers to early elementary. My son got hooked on its vibrant graphics and fun interactions.
Also, don’t sleep on Mathway. Although it’s mainly a math solver, it can help older kids understand step-by-step solutions to algebra and more. It’s kind of like having a math tutor in your pocket.
For something a bit different, try Bedtime Math. It’s not an app but more of a daily math problem series wrapped in funny stories you can read together at bedtime. Makes the learning casual and fun.
If your child prefers a more competitive edge, consider XtraMath. It’s free and focuses on building speed and fluency in basic math facts. It’s less flashy but quite effective.
Sorry, but I’ve found SplashLearn to sometimes feel a bit too basic for older kids, so depending on your child’s level, mileage may vary. But hey, different strokes for different folks, right? 
Those picks cover several ages, but a no-app routine might work better and cost nothing. Set aside 10 minutes daily. Use coins, beans, dice, or playing cards for counting, addition, and multiplication. Ask your child five questions based on daily tasks, such as totaling grocery prices or splitting snacks evenly. Track correct answers on paper each week. Aim for 8 out of 10 before raising the difficulty. Keep sessions short, praise effort, and stop before frustration starts. Its simple, practical, and easier to maintain.
Watch out with Prodigy specifically. The math itself is fine, but the game constantly dangles premium pets, gear, and zones your kid can’t get without a paid membership, and the nagging gets loud enough that some kids start caring more about the loot than the actual arithmetic. If your child is prone to that, it can quietly turn into a pestering-you-to-upgrade situation instead of practice.
@sudosys2 is honestly closer to what I’d do first. The dice and playing card idea works because there’s no screen fighting for attention and no upsell in the corner. One tweak though, the 8 out of 10 gate can stall a kid who’s slow but accurate, so I’d watch for frustration on the timing side, not just whether the answers are right. Speed comes later.
If you do want a screen tool, I’d lean toward the plainer ones like XtraMath for facts drilling. Boring, yes, but there’s nothing to buy and nothing to distract. Save Khan Academy Kids for the younger end since it thins out fast once a kid is past early elementary. My honest take is pick one app and one offline routine, not four apps. Kids bounce between too many and end up finishing none of them.
