🎲 Chance
A child who focuses only on the outcome being asked about may say the chance of drawing red is simply "3", forgetting that chance compares that count to everything else in the bag.

- Chance counts how many outcomes fit out of all the possible ones.
- The bottom is the total, including the items we did not ask for.
- A bigger chance means the outcome takes up a bigger share of the bag.
- A chance of zero is impossible, and a chance of one is certain.
The mistake most kids make here
Counting the ones that fit and forgetting the rest.
Try one question
A bag holds 3 reds and 5 blues. What is the chance of red?
3 reds, 5 blues
- 3 out of 8
- 3 out of 5
- 5 out of 8
Answer
3 out of 8 — That's it. The bottom counts everything in the bag.
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: Say the chance of drawing red from a bag with 3 reds and 5 blues.
How to help at home
Chance is a comparison, not a count on its own — it asks how big a share one kind of outcome takes up among every possible outcome, including the ones nobody asked about.
Fill a small bag or cup with a mix of objects — say 3 red buttons and 5 blue buttons — and have your child count the reds, then count everything in the bag, out loud, separately.
Ask: "if you reached in without looking, how many total things could you possibly pull out?" That total is the bottom number; the reds alone are only the top.
A sign they have it: given a new mix of objects, they state the chance as one count out of the total without being reminded to count everything first.
Questions parents ask
- Why does my child say the chance of red is just "3" instead of "3 out of 8"?
- They are counting only the outcome being asked about and forgetting that chance needs a comparison to everything possible, including the outcomes not asked for.
- What is a hands-on way to practice simple chance?
- Use a real bag of mixed objects and have your child count the ones being asked about and the whole bag separately, out loud, before stating the chance as one count out of the other.
- What does a chance of zero or one mean?
- A chance of zero means the outcome cannot happen at all — none are in the bag; a chance of one means it is certain — every item in the bag matches.
- How does Maya teach simple chance?
- Maya has the child count a real bag's total before naming the chance of one outcome, so the bottom number is never skipped.
