Welcome to Mathnasium of West Linn

Center Director
Hello. I'm Bruce Withycombe, Owner/Director of Mathnasium of West Linn, your neighborhood math-only learning center. We help kids in grades K-12 understand math by teaching the way that makes sense to them.


When math makes sense, kids leap way ahead – whether they started out far behind or already ahead in math. Our formula for teaching kids math, the Mathnasium Method™ has transformed the way kids learn math for over a decade across 1,000+ centers in the US and Canada:

  • We know how to teach your child math.
    Our specially trained math instructors will teach your child how to understand math in an individual setting – our unique approach enables us to effectively explain math concepts and lend a helping hand to every student. Our tutors foster a caring, encouraging environment that helps kids thrive and learn!

  • We pinpoint your child’s learning needs, meet them where they are, and take them where they need to go.
    Mathnasium instructors use our unique assessment process to determine (with great accuracy) exactly what each child knows and what they need to learn. Next, we design a customized learning plan for teaching the concepts the student needs to master. It doesn’t stop there – our encouraging instructors continually check progress along the way to make sure kids truly understand and retain the concepts we’ve taught. The results are transformative – kids will see measurable changes in attitude, confidence, and school progress.

  • We will help your child overcome homework frustration.
    Our instructors will also set aside time to provide homework help. We help kids understand the homework assignment so they feel better prepared to complete the work at home – underscoring their understanding of concepts and transforming homework frustration into a welcome challenge.

Special Note for West Linn - Wilsonville School District Families
Unlike most other local school districts, all incoming Freshman at West Linn and Wilsonville HS are automatically placed into Geometry or Advanced Algebra (Algebra 2). This means that all 8th graders will be introduced to Algebra 1 before high school even starts. The result is that by the time your child finishes 6th grade, he or she should be able to meet 7th grade 'State of Oregon' standards. Put more plainly, K-6 graders in our district are one year further behind than you think they are.
What does this mean for your students?  It means that they'll need to make 1 year of additional progress in math while in primary school (through 5th grade) and have extra solid fundamental skills in order to be ready for high school math before 8th grade starts.  Luckily, that is exactly what Mathnasium is designed to do: Math builds upon itself, so it is crucial to fill in any gaps before introducing tougher skills. By teaching kids 'Number Sense', they learn to think on their feet, independently, and become better prepared for the future! Call us, we can help!

Also available in your area, real-time face-to-face instruction over an internet connection.
