MathLibs offers multiplication practice and short slide presentations on various math strands. Multiplication practice is in the format of a word problem. Before starting the problems, players input several different names based on prompts. The prompts ask for teacher's names, boys and girls names, annoying boys names, etc. (like Mad Libs). These names are then inserted into the word problems to be solved. The slide presentations offer short tutorials on numbers, patterns, measurement, geometry, graphing, and probability.

tag(s): charts and graphs (197), measurement (179), numbers (191), patterns (87), probability (135)

#### In the Classroom

Use the slide presentations as an introduction to new math units or as review before quizzes and tests. Create a link on your website or blog for students to practice at home. Use the MathLib word problems as examples, then have students create their own MathLib problems and share them on a class wiki.

This site provides lessons with hands-on math using a Mobius strip (or band). Though the site is "plain vanilla," this topic always fascinates students. Directions are included for creating the strips along with a link to printable blackline masters to use. A simple, mathematically important, and wonderfully entertaining two-dimensional object, also known as the Mobius strip, that has only one surface and one edge and is therefore of great interest in topology. It is used in classrooms to develop understanding of surfaces and create mystery. Lessons build upon each other and give stopping points for each grade level. Pictures would have been helpful to demonstrate the activities; however, the site is still useful with providing lessons using the bands. More information on Mobius bands can be found here.

#### In the Classroom

During the lessons, take digital pictures of the procedures for creating and working with the Mobius bands. Older students can search for examples of Mobius bands used in the real world and create a classroom display.

Most activities have an interactive element and printable recording sheet that can be used by students. Students can input their own figures which makes the activities less repetitive and more interesting.

tag(s): data (155), multiplication (209), probability (135), time (139)

#### In the Classroom

This site contains many visual explanations of Math topics including interactive practice activities. Each explanation begins with a definition of the topic (such as adding or subtracting fractions), then moves on to practicing the skill with the interactive pieces. Practice activities at the end of each topic are very visually appealing and will appeal to most students. One of the most useful portions of the site is the glossary which contains definitions of many Math terms along with examples of the terms in use.

tag(s): charts and graphs (197), fractions (229), integers (40), puzzles (205), statistics (125)

#### In the Classroom

This site would be useful for students to practice skills already learned; however, the explanations are not in-depth enough for beginning to learn concepts. Create a link on classroom computers or in the computer lab to use as practice. Use the glossary as a resource on your interactive whiteboard or projector when definitions are needed for math terms. Provide a link on your class website or blog to the glossary for students to access at home. Display the site on your interactive whiteboard, choose a subject such as adding/subtracting fractions, then click the link titled "topic" and choose the final item in the sequence - in this instance it is an activity called The Small Flood. These activities are perfect for whole-class practice in each subject.
