A zero in the middle of a number looks like nothing to a child, so it gets skipped — "205" becomes "twenty-five" — even though that zero is doing real work.

How Maya teaches it
Your child tells Maya what they did in class. She teaches this topic at her desk, asks questions with tappable answers, and when the answer is wrong she explains why that answer was tempting instead of saying “try again”. She remembers what did not land and comes back to it.
Your child has it when they can: What is different in 205 versus 25?
How to help at home
Every digit in a number has a fixed home — hundreds, tens, ones — and a zero in one of those homes means that home is empty, not that it isn't there. Skipping the zero is really skipping a whole place, not just a digit.
Build numbers with real objects: use groups of 100 (a full egg carton, or ten stacks of ten coins), single tens, and single ones. Build 205 as two hundreds and five ones with nothing in the tens spot, and ask your child to read it out loud looking at the empty middle spot.
When your child reads 205 as "twenty-five", say: "point to the hundreds, then the tens, then the ones" and have them name what's in each spot, including "nothing" for the empty one, before saying the number.
A sign they've got it: they can explain what's different between 205 and 25 — that 205 has hundreds and an empty tens spot, while 25 has no hundreds at all.
Questions parents ask
- Why does my child skip the zero when reading a number like 205?
- A zero looks like nothing worth saying, so children often read only the digits that feel meaningful to them. Naming each place — hundreds, tens, ones — out loud, including the empty one, is what fixes it.
- What age do kids learn numbers up to 1000?
- This is typically a grade 2–3 topic, once a child is confident with two-digit place value and ready to add a third digit.
- What's a good way to build numbers like 205 at home?
- Use groups of ten household objects — coins, buttons, pasta — bundled into tens and hundreds, and have your child physically place them into hundreds, tens, and ones columns before reading the number aloud.
- How does Maya teach three-digit numbers?
- Maya asks how many hundreds are in a number like 205 before asking for the whole number, so the empty tens spot has to be noticed rather than skipped.
