Selected sections from books used in LAUSD Adult School Math Labs have been cross-linked (below) to common categories of math topics. Clicking on a topic will take you to an Instruction Links page where you can find web pages and videos that help explain the math for that topic. When you get to the Instruction Links page, the category you're looking for should be somewhere in the visible part of the page (usually at the top). If a particular page from your book is not listed below, it's probably because we don't have, at present, a corresponding category covering the topic on that page. But you might want to check the Miscellaneous section of the Instruction Links page --or just Google the topic you're interested in (that's how we found them)! Lastly, if you click on a video link and nothing happens, then your school probably has blocked the source (eg, YouTube or GoogleVideo), but you will still be able to see the video from outside of school.
