Math Concept Videos

The math department is producing videos to help you implement the SFUSD Core Curriculum and the Common Core State Standards for Mathematics. We currently have three types of videos: Videos that help explain complex math concepts, videos that illustrate the SFUSD Signature Strategies, and videos that introduce some of our preferred technology tools.

On our YouTube channel, you can also find a growing library of video podcasts that preview the mathematics in each unit in the SFUSD Math Core Curriculum (Grades K–5 and Algebra 1). If there are other videos that you would find helpful, please let us know by sending us a note via our contact form.

Multiplication of Decimals

This 6 minute video shows how to use Base 10 Blocks to model multiplication of decimals.

Here is another video for this topic:
A video from Graham Fletcher about the progression of multiplication and the conceptual development of the standard algorithm.

Division of Fractions

This 8 minute video discusses how to think conceptually about division of fractions.

Here are more resources for this topic:
A nifty video about partitive and quotitive division from PBS Learning.

This succinct paper from Donna Curry (TERC) explains many of the ideas in this video.

A video from Graham Fletcher that traces conceptual understanding of division from Grade 3 to Grade 6.

Composition and Decomposition of Numbers

This 3 minute video discusses composition and decomposition of number from Kindergarten through 3rd grade and beyond. It also explains subitizing and how it supports decomposition of number.

Two Way Tables

What are Two-Way Tables? How are they created? How do we make sense of them?
This 3-part video series shows how to construct and use two-way tables to summarize bivariate categorical data by displaying frequency and relative frequency for rows and columns and identify patterns of association between the categories.

Visual Models for Reasoning about Ratio and Rate

How can we use tape diagrams and double number lines to support student reasoning about ratio and rate?
This 2-part video series shows how to use tape diagrams and double number lines to support student reasoning. Tape diagrams illustrate number relationships and double number lines can be used to represent rate problems.
