You might think the printed phone book is obsolete. Not true! The phone book is a great teaching tool for reading and ESL classes. Skills that can be exercised include spelling, research using reference tools (how is it organized?, where can I find the information? how does cross referencing work?) and critical thinking (what category would this be listed under?).
This product includes a 19-slide Powerpoint presentation that explains the white pages, yellow pages, blue pages (government listings) and community information pages. It also includes a 2-page worksheet in which students use the phone book to look up information.
These skills are transferrable to online research. Indeed, the whole worksheet can be done using the phone book, and then repeated using the internet for an interesting compare/contrast experience.
