💰 Shekel and agorot decimal
The digits after a decimal point look, to a child, like just more digits of the same number — so "1.5" gets read as "fifteen" instead of "one and a half", because the point itself doesn't seem to change anything.

- In one shekel there are a hundred agorot.
- What is written before the point is whole shekels.
- What is written after it is parts of a shekel, not shekels.
- Two digits after the point, because every shekel has a hundred agorot.
The mistake most kids make here
Reading the digits after the point as a whole number.
Try one question
The number 1.5. What does it say?
1.5
- fifteen
- one and a half
- five
Answer
one and a half — Yes. One whole, and a half.
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 do the digits after the point mean in money?
How to help at home
Money is the clearest real-world place a child meets decimals, because a shekel and its agorot are genuinely two different kinds of amount — whole shekels, and parts of a shekel — even though they're written as one number with a dot between them.
Use real coins. Lay out one whole shekel coin and a fifty-agorot coin next to it, and write "1.50" above them, pointing at the point separating the two piles: one whole shekel, and fifty out of a hundred agorot.
When your child reads "1.50" as "one hundred fifty", say: "before the point is whole shekels, after the point is parts of a shekel — let's count each pile separately" and recount the coins on each side.
A sign they've got it: they can look at a price like 3.25 and immediately separate it into "three whole shekels" and "twenty-five agorot" without needing to be reminded what the point means.
Questions parents ask
- Why does my child read 1.5 as "fifteen"?
- The digits after the point look like an ordinary number to a child who hasn't yet separated "whole amount" from "part of a whole". Counting real coins on each side of the point makes the difference concrete.
- What age do children start learning decimals?
- Decimals with money are often a child's first exposure, typically around grade 5, before decimals are used more generally in other math contexts.
- Why are there always two digits after the point in money?
- Because a shekel is divided into a hundred agorot, so two digits are exactly enough to say any number of agorot from 0 to 99 — a third digit would need a different unit smaller than an agora.
- How does Maya teach decimals with money?
- Maya asks the child to separate a price into whole shekels and agorot before asking what the number means overall, so the point's job becomes clear before any calculation.
