Should your child use Photomath for maths homework? Here's what parents need to know
Calculator apps can be a genuine study aid or a homework shortcut that quietly hides a growing gap. Here's how to tell which one is happening in your house.
Your child is stuck on a maths problem. Instead of calling you over, they pull out their phone, snap a photo of the question, and thirty seconds later the answer appears — fully worked out, steps included. Homework done. Except it isn't really done, is it? You just watched an app do the thinking your child was supposed to be doing.
Photomath, and apps like it, have become as much a part of South African homework routines as a scientific calculator once was. Parents are understandably torn. Is this cheating? Is it a legitimate study tool? And how do you even monitor it when the "cheating" happens silently, on a device, in five seconds flat?
The honest answer is that calculator apps aren't inherently good or bad. What matters is how — and when — your child is using them.
What these apps actually do
Apps like Photomath use image recognition to read a maths problem from a photo, then generate a step-by-step solution using pre-programmed rules for that type of problem. Used properly, this can look a lot like a private tutor showing worked steps. Used badly, it looks like a shortcut that skips learning altogether.
The difference isn't the app. It's whether your child stops to read and understand the steps, or simply copies the final answer into their homework book and moves on to the next question.
When calculator apps genuinely help
- Checking their own attempt. If your child has tried a problem, gotten stuck partway, and uses the app to see where their working went wrong, that's productive — it's a check, not a crutch.
- Spotting a specific misunderstanding. Comparing their steps to the app's steps can reveal exactly where a sign was flipped, a step was skipped, or a rule was misapplied.
- Unlocking a genuine "stuck" moment. After several honest minutes of effort, seeing one worked example can be the nudge that gets them moving again — much like a parent or tutor showing a similar sum.
Used this way, a calculator app functions like an answer key with explanations attached.
When they quietly undermine learning
The trouble starts when the app becomes the first move rather than the last resort. If your child photographs every question before attempting it themselves, they're not practising maths — they're practising photography. No struggle happens, no memory is built, and no skill transfers to the next test, where there's no app allowed at all.
This matters more in South Africa than almost anywhere else, because CAPS assessments and the matric exam are entirely calculator-app-free, and often even restrict which physical calculators are permitted for certain sections. A child who has outsourced their homework thinking for two years arrives at test day with no practised muscle memory to fall back on — and the gap shows up as a mark, not a shortcut.
Homework that's finished in record time with no visible working isn't a sign your child has mastered the topic. It's often a sign the app has.
- Homework is finished unusually fast with little or no visible working
- Test marks are consistently much lower than homework marks
- They can't explain their answer out loud when you ask them to
- They seem anxious specifically about "showing steps" in class
A healthier alternative: build the skill, not just the answer
If your child is reaching for a calculator app out of genuine stuckness, the real issue usually isn't laziness — it's a gap somewhere earlier in the curriculum that makes the current work feel impossible without help. That's a different problem, and it needs a different fix than simply banning an app.
This is where consistent, targeted practice does more good than either a tutor session once a week or an app that hands over instant answers. Equals2, a maths practice app built for South African Grade 1–12 students, takes the opposite approach to a calculator app — instead of solving the question for your child, it tracks which topics they're actually weak on and serves practice questions to build real understanding in those specific areas. If a gap traces back a grade or two, students can go back and strengthen that foundation directly, rather than papering over it question by question.
The goal isn't to remove every source of help. It's to make sure the help your child is getting builds a skill they can use again on the next test — not just an answer for tonight's homework.
The bottom line
Calculator apps aren't going away, and pretending your child will never open one isn't a realistic strategy. What you can control is how they're used: as a way to check understanding after genuine effort, not as a substitute for it. Watch for the warning signs, have an honest conversation about when these tools help and when they hurt, and pair any homework support with practice that actually builds the underlying skill.
