Looking for a way to integrate literature into your math lessons? Check out this site featuring three famous pieces of children's literature: A Light In The Attic, Counting on Frank, and How Big Is a Foot?. These stories are used to teach and reinforce math skills such as geometric figures, estimation, volume, measurement, and more. Some of the lessons include exploring the size of humpback whales, creating "beds" using their footprints, and other creative ideas. Many of these lesson plans and coordinating activities require Adobe Acrobat. You can get it from the TeachersFirst Toolbox page.

tag(s): estimation (48), literature (272), measurement (178), volume (53)

#### In the Classroom

Take advantage of these FREE lesson plans! Read the stories together as a class. Have students create their own math stories (about geometry or another topic you are teaching). Challenge cooperative learning groups to create online math-based stories using a tool such as Bookemon (reviewed here).

This site provides countless books, films, plays, and television shows that all relate to specific math concepts. What a fabulous way to integrate math, language arts, history, and more! The site includes the title, year, and brief description. Teachers can browse by genre, medium, motif, and/or topic. Media include everything from comic books to plays to television series. Genres include historical fiction, children's literature, adventure/espionage, fantasy, science fiction, and more. Sixty-three fiction offerings are even available FREE (in their entirety) online! The site is still developing and frequently adds additional fiction titles. Students who enjoy fantasy will also enjoy choosing books from this site, since the author admits that not all math mentioned in all the books is "real" math!! The site allows teachers to search by keyword and also to browse new offerings in the compilation of titles.

Looking for extra practice and better ways to track student progress? Use this free site for explanations of concepts, see example problems, and answer a practice problem. The English is British style, so remember that "revise" on this site means the same as "review" to Americans. Teachers can register their students to follow their progress. Registration is free, but does require an email address. If you plan to have students register individually, you may want to create your own Gmail account with up to 20 subaccounts for each group of students (by code name or number) within your classes. Here is a blog post that tells how to set up GMail subaccounts to use for any online membership service.

Data on correct and incorrect answers as well as strengths and weaknesses are kept for students. This site does include some minor advertisements. Watch out for a link to "essay paper" buried at the far bottom right on the home page: a place to purchase essays online!

tag(s): coordinates (30), exponents (43), fractions (229), integers (40), percent (81)

#### In the Classroom

Use this site for extra practice or answering a problem after initial teaching. Identify strengths and weaknesses for grouping students in solving problems. Share this link on your class website for students to use for extra practice and as a resource outside of the classroom.

There are also activities connecting math to physics and astronomy.

tag(s): geometric shapes (173), symmetry (51), tessellations (6)

#### In the Classroom

Use many of the images as an introductory inquiry activity to get students thinking about shapes and space. In art class, use the tiling activity and others on a projector before having student create their own on paper. Share the activities on your interactive whiteboard or projector. Provide images to groups to explore and identify the underlying math concepts present in the artwork. Provide an opportunity for some groups to create their own work with a geometric shape that they are investigating. Follow up with student projects of the geometric shape or photographs of geometric shapes in nature and man-made structures.

This site features 13 geometry questions, a printable "dot paper," and a link to a virtual Geoboard. Some of the topics (of the questions) include square roots (of 2 - 40), lengths of irrational numbers, and diagonal irrationals. The virtual Geoboard opens in a new window, so you can easily navigate between the questions and the Geoboard.

tag(s): numbers (197)

#### In the Classroom

You have several options to use this site with your geometry students. You could print out the "dot paper" and display the question on an interactive whiteboard or projector, while students work independently at their seats and selected students share on the whiteboard (resist the urge to be Vanna White yourself). You could also share this site using the interactive Geoboards. If individual computers are available, you could have students try the 13 questions using their own interactive Geoboards. Have cooperative learning groups create 2-3 additional questions (related to the topic) for the class to try. Share them on your class web site for students to challenge one another.

tag(s): pi (28)

#### In the Classroom

Have students work in cooperative learning groups to complete this Webquest. Share the introduction on your projector or interactive whiteboard. Rather than having students use YouTube to share videos, as the WebQuest suggests, have students try an educational video sharing site such as TeacherTube TeacherTube (explained here). For the Youtube video on the site, teachers whose school filters the site may not be able to access it. Instead, rip the video from a site such as KeepVid reviewed here to download the videos from YouTube.

This simple website should inspire you to make your own WebQuest to invigorate learning. (This one used Googlepages, but there are many other internet hosting sites that offer free or nearly free pages. Learn more about webquests at TeachersFirst's Webquest 101 and read a review of a possible tool, zwebquest, here here.

This site features engaging movie scenes (in Quicktime and Flash formats) that involve Math problems. Beside each clip and title is an explanation of the Math concept in the clip. Most are secondary level, but a few are for lower grades. If you click on the TITLE of the movie, you will be lead to a site to purchase, rate, and/or view the movie in its entirety. To avoid this confusion, be sure to click on the "Play the Flash Version or QuickTime" links. These links lead directly to the "math clip." Links at the bottom lead to other movie collections websites.

tag(s): logic (247), movies (70), patterns (87)

#### In the Classroom

Use the links "Begin of Lectures in College teaching" and "The end of lectures in college teaching" to identify effective and ineffective teaching elements at all levels. Use these clips for anticipatory set or activators at the start of a lesson or introduction of a concept. Share the video clips on your interactive whiteboard or projector. Discuss the concepts as a class or have students work in cooperative learning groups. See if students can identify any other movie or television show that has used math concepts. If time permits, have students create their own mini-dramas that include discussion of math concepts within the story.
