Math in Focus 2020 Grades Kindergarten-3rd Grade


Marshall Cavendish and Houghton Mifflin Harcourt teamed up for this updated version of one of the original Singapore math series in the United States. In this edition, students are challenged with tough problems and problem-solving opportunities through a new and improved student book. Students will explore math concepts using the concrete-pictorial-abstract theory and visualization to make sense of operations.

Videos for Educators


Each 2-10 minute video can serve as instant professional development. While 80% of the videos are student-centered, some videos are designed to give teachers teaching tips and strategies to implementing the curriculum effectively.


School educators, home educators and parents supporting their students at home are welcome to view any video as a way to prepare for a lesson or support a student's learning.


Videos for Students


There are 400+ videos aimed to engage students during their math lesson. Whether used as a preview of the lesson in the textbook, a way to sum up the lesson or part of the instruction, students can grab their math manipulatives and engage in the video lesson.


Videos are taught by a certified teacher with over 16 years of experience as a classroom teacher and national math consultant for Singapore math programs. Jessica was even on the author team for this series as the author of the Grade 3 Teacher's Guide.



Textbook Driven


Each video library course subscription is aligned to the table of contents in each book. Since most of the videos are topic-based, these videos highlight the best strategies regardless of the specific problem.


A full list of videos is shown in the folder below. New videos are uploaded monthly and can be requested.

This course is closed for enrollment.

Frequently Asked Questions


How do you use the video library?

The video library is designed to be used as 5-10 minute lessons for student instruction. These can be done as an introduction before the lesson or as part of the opening task. Some educators may choose to watch the video as professional development when preparing for a lesson. Students may also reference the videos as review of previous concepts or as part of the lesson itself.

Who should use the video library?

The video library is available to any type of educator- whether a parent, homeschool educator or classroom teacher. These videos are designed to support any student to help instill a love and understanding for mathematics.

What curriculum do the videos teach?

The videos are concept based. That means you can use the video as an introduction or review for your lesson. Students should be able to connect the video to the specific problems in the book by seeing the way the concepts are taught.

Why is there not a video for every single lesson?

This is a growing video library. Videos are designed with the most complicated concepts presented first. Additional videos are added monthly with requests always being taken.

Do these videos take the place of the lesson?

A true Singapore math-style curriculum should include problem-solving and hands-on learning. Each video is designed to include a real-life situation and an opportunity for your student to interact with the content by pausing the video and participating. These videos should be used as a way to engage in the content in a thoughtful way before completing the textbook practice problems.

What makes these videos different from YouTube?

While there are many wonderful resources out there, it can take time to find quality content that will give your student the best information in the shortest amount of time. These videos are designed and hosted by a published author of two US Singapore Math textbooks and a certified educator and consultant who has trained students all over the world for over 16 years. These lessons have been tested with various students and proven to get results.

Why do I need access to multiple grade level videos?

Part of what makes this video library unique is that it includes multiple grade levels at one great price. Use the lower grade videos to review concepts and the upper grade videos to extend concepts. This video library is designed to show how concepts are developed from the beginning through multiple grade levels. 

What if I decide I want to change my membership option?

Monthly plans are available for a 14-day free trial and can be cancelled at any time by cancelling within your account. You can also change your membership level, update payment information or make any account changes.
