Five minutes into homework and the ADHD brain is somewhere else. If that sentence describes your house, you are not alone, and your kid is not behind because they are not trying.
Here is what I have learned, as a mom and from talking to a lot of parents in the same boat: kids with ADHD usually do not struggle with times tables because the math is too hard. They struggle because every common way of practicing demands the exact things ADHD makes hardest. Sit still. Focus on demand. Repeat the boring thing until it sticks.
So stop fighting that battle and change the practice instead.
Make it physical
An ADHD brain holds onto what the body does. Tracing, tapping, fidgeting with the numbers in hand: all of that counts as practice, even though it does not look like school.
Drop the timer
Timed drills measure speed, not knowledge, and for an anxious kid they measure panic. Practice at the child's own pace, a few minutes a day, and the facts arrive without the fight.
Let them check instead of freeze
A lot of kids with ADHD shut down when they are afraid of getting it wrong. Having the facts somewhere they can glance at, instead of having to pull them from memory under pressure, keeps them in the game.
Work with the fidget, not against it
If your kid needs to move to think, give the hands something math-shaped to do. It is not distraction. It is how their brain files things.
Keep it screen-free if screens are a trap
For some kids an app is a tool. For others it is twenty minutes of practice and forty minutes of everything else the tablet offers. You know which one you have.
What worked for us
The facts live on her wrist now. She wears a MathBands bracelet for whichever facts she is working on, and she traces them while she fidgets. No timer, no app, no sitting still required. The school used to see the ADHD before it saw my kid. Now the facts just show up.
Start with one change. Drop the timer, or let them trace, or take the practice off the screen. Small shifts, a few minutes a day. That is the whole method.
