What your child learns

The mistake most kids make here

Adding 1 instead of jumping.

Try one question

2, 4, 6. What next?

2, 4, 6, ?

Answer

8 — That's it. Two more after 6 is 8.

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: Skip-count by 5 to 20.

How to help at home

Skip-counting means jumping by the same amount each time, and it only sticks once a child feels the size of the jump, not just hears the numbers.

Try it as a hopping game: mark five spots on the floor with tape or paper two steps apart, and have your child hop and say "2, 4, 6, 8, 10" as they land on each one. The physical jump size matches the number jump.

If they answer with the next number instead of the next jump (say "7" after "6"), say: "that's counting by ones — we're jumping by two, watch," and hop the jump again together before asking.

A sign they've got it: they can start skip-counting by 2 or 5 from a number in the middle — like continuing 5, 10, 15 from a card that only shows "10, 15" — not only from the very beginning.

Questions parents ask

Why does my child add 1 instead of skip-counting by 2?
Counting by ones is the older, more automatic habit, so it takes over under pressure. Physically hopping or stepping the size of the jump helps the brain register "we add two here," not just "a number comes next."
Why does skip-counting matter for later math?
Skip-counting by equal jumps is the direct groundwork for multiplication — counting by 5s five times is the same as 5 × 5. Children who skip-count comfortably tend to learn times tables faster.
Should we practice skip-counting by other numbers too, like 3 or 10?
Grade 2 usually focuses on 2, 5, and 10, since those come up most in daily counting (pairs, hands, coins). Other numbers like 3 can wait until skip-counting by 2 and 5 feels automatic.
How does Maya teach skip-counting?
Maya presents the next-number mistake directly — like offering "7" as an option after 2, 4, 6 — and asks the child to notice the jump size before choosing, rather than only marking the final choice right or wrong.
