Using the Primary Mathematics 2022 Video Library


As one of the authors of the Teacher's Guides and Home Instructor's Guides, I realize what students need to work successfully through this series. They need to see how manipulatives and visuals can work with thoughtful questioning to dive deep into concepts. Each 5-10 minute video can be used to supplement, review or prepare for a successful lesson through the three video types:

  1. Videos for Educators: Videos to prepare educators about the chapter or teaching methods.
  2. Concept Based Videos: These videos apply to the concepts in each lesson. Students can watch the video before their textbook lesson or even as a review.
  3. Specific Problem Videos: These videos are designed to be viewed while working on a problem from the textbook.

With the flexibility of this growing library, educators and students can use this to master content with ease!

What curriculum do the videos teach?

The videos are a mixture of topic based videos that apply to various lessons and specific videos for Primary Mathematics 2022. Exclusive videos for Primary Mathematics 2022 will reference the page number and encourage students to use their textbook.

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?
