Mia
The noticer · Leo's sister
Mia spots the patterns first: flags at the market, stripes on socks, the next color in line. She counts everything, from toys in the basket to stars on the blanket.
Red, yellow, red, yellow. The next flag is red.
A Day on Maple Street
Spend one Saturday with brother and sister Leo and Mia, Grandma Jo and Nori the cat. From breakfast pancakes to bedtime stars, they find math in every corner of their street — and teach your child to find it too.

Meet Mia, Leo, Grandma Jo and Nori
Brother and sister Leo and Mia, Grandma Jo and Nori the cat live on Maple Street, where there's a math moment around every corner. Each one notices numbers in their own way.
Leo
The builder · Mia's brother
Leo learns with his hands. He counts steps on his step counter, stacks block towers, measures out the flour and finds the shortest path on the map.
That path has five blocks.
Grandma Jo
The guide
Grandma Jo turns everyday jobs into gentle lessons. Pancakes become fractions, muffins become measuring, and the bus timetable becomes telling time.
One pancake can become equal parts.
Nori
The cat who's always there
Wherever Mia and Leo go, she follows. Nori counts toys in a very cat-like way, guards the soccer goal, naps in any box she can find and much prefers wagon travel to walking.
Even a cat can guard a rectangle.
One day, eighteen math moments
The story follows a single Saturday from waking up to falling asleep. Keep scrolling to live the day with Mia, Leo, Grandma Jo and Nori. Tap a sample page to read it.
Three sample pages are open to read; the rest are waiting in the book.
Then it's your child's turn
After the story come six activity pages that bring Maple Street off the page: a math challenge, Nori's hidden-math hunt, a draw-your-own street, a "My Math Day" journal page and a busy street scene to search.
The last page is a Maple Street Math Explorer certificate with your child's name on it. Nori's Math Hunt is open below as a sample.
Help Nori find the math
Six quick puzzles straight from the book. Read them aloud together and let your child tap the answer.
Ready? Let's hunt!
For grown-ups
You don't need to be a "math person" to use this book. It works best when it leaves the page.
Read one page at a time
Each page stands on its own. Read the story, then ask about the speech bubble: "How did Mia know the next flag was red?"
Find it in your own day
Cut a pancake into quarters. Count steps to the corner. Guess which jar has more pasta. The book gives you the words; your kitchen gives you the practice.
Finish with the activity pages
The challenges at the back check what stuck, and the certificate gives your child something to be proud of.

Written for ages 3–8. Younger children enjoy finding Nori and counting things on each page; older children can work through the questions on their own.
