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. 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 DecimalsThis 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. 

Two Way Tables
What are TwoWay Tables? How are they created? How do we make sense of them?
This 3part video series shows how to construct and use twoway 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 2part 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.
