About this tutor

Experienced tutor with over 20 years classroom experience.  Best qualifed to work with students age 9 - 14.  All subjects.  Expertise in math and supporting students to learn how to love working with numbers.  Singapore math is a focus where students learn to model their word problems.  Numerous references available upon request.

Working one-on-one with students brings a certain reward.  I love discovering what makes each individual tick.  Each learner is different and takes in material in ways unique to their own style.  Uncovering that mystery brings me great joy.

What is your typical process for working with a new student?

Generally, I start by talking with the parents privately to discover what they want achieved through the sessions.  Then I work individually with the student and provide various assessments to determine their strengths and weaknesses.  I am happy to provide baseline data and bi-weekly progress reports specific to each learner.
