Hi! I'm Off-Kilta Matilda®

I’m in the second grade and I’m a ladybug. I love math and playing outside. I have a pet worm named Archi, and I was having a very hard time in school.

Most of my bug friends have identical spots on their wings, but I have 5 spots on one wing and 6 spots on the other. Some of the kids in my class made fun of me and so my mom and I started the Prime Number Club®.

The Prime Number Club® is fun and you can join today. We get to talk about math and solve mysteries using prime numbers. My mom is kicking things off with the book, Off-Kilta Matilda®, and we will have updates on our books, club, worksheets, and coloring pages.

Order the book, plush, and tote today—check out "The Buzz" about STEM on our blog.

We have a vision where girls (and boys) will have fun and rally around math and science. We worked with experts from around the US to develop a series of books, teaching guides, coloring worksheets, cartoons, and games.

We have a vision of self-confident kids that embrace their spots, love STEM, and have fun investigating math and science.

We would love to see the Prime Number Club® used in schools, on bookshelves, and have big dreams that one day we will see Off-Kilta Matilda® on the big screen!  If you want to learn about the Prime Number Club® and Off-Kilta Matilda® please call or email. We love to bring Off Kilta Matilda® to schools and summer camps.
