## Our 25th Anniversary!

25 years ago my parents introduced the original Primary Mathematics textbooks and workbooks to a few parents in our community of West Linn, Oregon. We had just moved from Singapore where I had attended public school, and, unimpressed by the math education at my new school, my parents wondered if other students and parents might benefit from the Singapore math curriculum. The need and interest were certainly there. Hardcore homeschoolers, university math professors, and pioneering school principals from across the country dove in deep and started championing Singapore math, spreading the word on why it was so effective. One thing led to another and we kept creating new content to make Singapore math more accessible to more people.

Now it’s 2023 and we’re still family-owned and operated, and still dedicated to our original mission of bringing this model of math education to as many students as possible. While Singapore math still isn’t exactly mainstream, many of its most effective concepts have been folded into mainstream math programs, and we’re so proud of all the ways it’s contributed to greater understanding and success for math students. Thank you for being here. We love your passion for Singapore math!

The New York Times captures Singapore math's unique position: "Singapore math’s added appeal is that it has largely skirted the math wars of recent decades over whether to teach traditional math or reform math. Indeed, Singapore math has often been described by educators and parents as a more balanced approach between the two, melding old-fashioned algorithms with visual representations and critical thinking."
