Use this interactive activity to help students improve spatial skills involving two and three-dimensional objects. After viewing the net of a two-dimensional object, students must try to figure out how it can be folded into a cube, then click on the net to watch the process. Next, after viewing a collection of nets, students must correctly identify those that will form a cube. Aligned to National Standards.

tag(s): geometric shapes (135)

In the Classroom

Include this interactive as part of a math center for students to explore the properties of cubes. Ask students to print out the different shapes to prove or disprove the ability to create cubes using the given features. Use Adobe Creative Cloud Express Video Maker, reviewed here and have students create video demonstrations showing the properties of cubes.

This fabulous collection of lesson plans, activities, and web links from NCTM is a professional treasury for math teachers. The two menu selections at the top, Lessons and Interactives, are actually drop down menus to find lessons by grade levels, Brain Teasers, Mobile Apps, a Web Sketchpad, and more. The interactives are a challenging practice for concepts ranging from basic fractions and graphing to congruence theorems. Narrow your search with keywords. Each activity includes a description and grade level recommendation. Highlighted activities and Lessons on the home page change often. Many lesson plans also include technology links, but others are low-tech or no-tech. Illuminations is created by NCTM.

tag(s): data (146), measurement (125), numbers (119), operations (72), probability (96)

In the Classroom

Keep this one in your professional favorites to find supporting technology for any math concept. As you find practice or extension ideas for student use or at home reinforcement, share specific links on your class web page or classroom computer center for students to access independently or as you assign them for needed practice. The full site is overwhelming for most parents, so share the specific areas that fit your curriculum.

This site allows you to create and print different types of graph paper in a PDF format. The site is easy to use and takes you through each step needed. First choose the type of graph paper from the eight different offerings including Cartesian (the most popular) and hexagonal. Next choose paper size, measuring units (inches or millimeters), then choose the paper created from the list offered. Just print after the graph paper is created.
This site includes advertising.

tag(s): charts and graphs (168)

In the Classroom

Save the site as a link for quick printing of graph paper when needed. Provide the link to students and parents to use at home when graph paper is needed. Quickly print graphs onto transparency film to use on overhead projectors.
 This resource requires PDF reader software like Adobe Acrobat.

This applet is perfect for practicing finding the area and perimeter of regular and irregular shapes. After a shape is shown, there are boxes to input the answer to the area and perimeter of the provided shape. Options are also provided to adjust the size of shapes, to allow only rectangular shapes, and to allow scoring. The learner portion of the site provides an overview of area and perimeter. Be sure to check out the instructor section for links to standards, information for classroom use, standards addressed, and links to similar resources. There is also a printable exploration questions worksheet that can be used in the classroom.

tag(s): area (52), geometric shapes (135), perimeter (20)

In the Classroom

Introduce this site on your interactive whiteboard or projector. Then have students complete the exploration questions either on their own or with a partner. After exploring the site, have students create their own shapes for other students to solve for area and perimeter. Ask students to write in their math journals about how the different shapes create differences in area and perimeter. Create a link on your classroom website or blog for students to practice at home.
