Word Problem Wednesday – Ava, Ben, and Carlos

This month’s Word Problem Wednesday problem comes from the chapter on the “Model Method and Algebra” from The Singapore Model Method for Learning Mathematics.

The book models the Unitary Method as well as 3 variations on an algebraic solution. The author’s end this problem with the following commentary

The Model Method is a means, not and end in itself. It helps students formulate an algebraic equation to solve the problem. While more able students can proceed quickly to the absract algebraic method to solve problems without drawing a model, others may still need to rely on drawing the model as a problem-solving heuristic.

-The Singapore Model Method for Learning Mathematics, p. 58

Wise words, indeed! On to the problem:

$120 is shared among 3 friends, Ava, Ben, and Carlos. If Ava receives $20 less than Ben, and Ben receives 3 times as much money as Carlos, how much does Carlos receive?

Celebrating 10 Years: Giving Thanks and 2018 In Review

In the spring of 2008, armed with tons of enthusiasm (and considerably less experience), I traveled to Bozeman, Montana, for my first-ever solo school training job.

At that time, I was already a huge fan of the Singapore Math program. I had taught it in several grade levels and collaborated with two teaching partners to write a 40-hour training program that was submitted to the State of California. I even traveled to Singapore on a week-long learning adventure to see the curriculum at its source. That trip was a life-changing experience.

Despite being nervous (OK, terrified), the school was pleased with my work. Over that summer, I visited another dozen schools and came to the delightful realization: I had discovered my life’s work.

Ten years on, my passion for mathematics education is as strong as ever; I’m so grateful for the opportunity to work with teachers in their classrooms on a regular basis.

By any measure, 2018 was a super successful year for me and Beth Curran, Math Champions’ trainer extraordinaire.  Over the past year, we worked with teachers at dozens of schools and presented at several educator conferences. We won international contracts and hosted highly-praised workshops.

This year will always be special for another exciting reason. (Drum roll, please!)

Dimensions Math Launched

It was an honor to be invited to join the core team writing Dimensions Math in 2016, and difficult to keep quiet about my role as reviewer and lead author of the Teacher’s Guides for K-5. Beth joined the Dimensions team in 2017 and is the co-author of the Kindergarten Teacher’s Guides.



All our hard work with Dimensions Math came to fruition in 2018. Dimensions Math was launched in April at the NCTM Annual National Conference to plenty of fanfare. I was thrilled to see the fruits of our labor; teachers’ positive reactions to DM was icing on the cake. To learn more about Dimensions Math, visit this page.

Making Math Make Sense

Thanks to all of our school clients who have put their trust in us. Partnering with teachers and schools is our core service and favorite role. Here’s what 2018 looked like in numbers (and we’re all about numbers, you know):

38 – Schools/districts/nations chose us to help improve their math instruction

24 – Repeat clients

15 – States visited

3 – Countries visited

2 – International Contracts Won through competitive RFP processes; we’re training teachers for Guam’s Department of Education and the Ministry of Education in the Republic of Palau!

When teachers tell us things like this about their time with us, we know we’ve found our calling:

 Beth -Thank you for your patience and understanding! I have so much confidence in our new program and have a new love for math! This truly was the most productive training I have been to in years.

-Kami Orbin, 2nd Grade, Mid-Valley Elementary School, Throop, PA

Cassy made training a joy! She had endless energy, sprinkles in lots of humor, and has so much knowledge of the material. She had endless resources and suggestions, offered help when needed. So approachable and patient. I like math now!

-Julie Bas, Director of the Lower Grades, Carden Hall, Newport Beach, CA

Jumpstart Your Singapore Math

Math Champions hosted Jumpstart your Singapore Math Workshops in four cities: Charlottesville, VA; Tulsa, OK; Fort Collins, CO; Saint Paul, MN. Teachers from 18 states attended these two-day workshops on how to best get started using the Singapore Math approach.


We are thrilled by the praise teachers have given this program:

 I have been in education for over a decade, and this has been one of the most engaging, practical, and meaningful Professional Development opportunities of my career. Thank you to these amazingly bright and helpful experts!

-Keith Griffin, 1st and 2nd grade Math Specialist, City Academy School, St. Louis, MO

This is the best training I’ve been to. Every minute was enjoyable and educational. I feel better going into the school year and am excited to teach the Singapore way. It was life-changing and mind-blowing!

-Jen Irish, 3rd Grade Teacher, Terra Academy, Vernal UT

Presentations at National Educator Conferences

We love to share what we’ve learned with our colleagues. We were honored that speaker proposals were selected and we gave presentions at the following conferences:

California Mathematics Council – South

We want to hear from you! Share your success stories or challenges and let us know how we can help you.

We’re busy planning for 2019. Much more in store next year…

  • Jumpstart in July: 5 venues planned for this popular summer introduction program.
  • Coaches Academy! Save the date: December 2-6, 2019.

An extra special thanks to our exceptional friends…

Happy New Year!
