Secondary students will appreciate this user-friendly bibliography helper. They still have to do the work of collecting all of the necessary information, but after entering it into the site, a citation with correct MLA format and punctuation is created for them. The citations can then be copied and pasted into a word processing document.

tag(s): citations (32)

In the Classroom

Have a student demonstrate how to use this tool on a projector or interactive whiteboard. Share this link on your class web page for easy use any time students have a research project. Model ethical use of resources by using it yourself to cite sources on handouts, etc.

From moving mathematical sculptures, to quick and simple radios, this searchable site addresses quite a collection of scientific concepts through easy-to-build science projects. Illustrated project instructions are highly detailed, and most require only common household items. A few use more specialized, but relatively inexpensive and easy-to-find materials. Topics include magnetism, light and optics, biology, mathematics, aerodynamics, and more.

tag(s): light (61), magnetism (40), optics (14)

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 (214), measurement (123), numbers (117), operations (70), probability (134)

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 interactive chart illustrates the discovery of Greek mathematician Eratosthenes, who recognized that to find all prime numbers between two and some larger number, it is necessary to remove ALL multiples of each number between them. To watch a visual illustration of this concept, click on each consecutive number, starting with two, and watch as multiples are eliminated. Eventually, all prime numbers between 2 and 400 will be highlighted in red. Sounds complicated, but this is a fascinating site to project in the classroom as prime numbers are introduced and discussed.

Put students in charge of making correct change with this quick, ready-to-go math game from Funbrain. Change Maker presents a purchase and asks players to calculate the change due, then enter their answer before submitting. Correct change is added to a virtual piggy bank, giving students immediate practice with money calculations in a simple game format.
This site includes advertising.

tag(s): counting (58), currency (10), money (112)

In the Classroom

Have students play several rounds independently, then record three problems from the game and explain the subtraction or counting-up strategy they used to find each amount of change. Assign students to compare two strategies for making change, such as subtracting the cost from the amount paid and counting up from the cost, then collect their explanations in a Google Forms exit ticket, reviewed here. Ask pairs to post one challenging purchase-and-change problem on Padlet, reviewed here, then have classmates solve and respond to several problems before discussing efficient strategies as a whole class.

Step into the history of secret messages with this collection of introductory readings about cryptography and encryption. The resource begins with an explanation of plaintext, ciphertext, encryption, and simple substitution, including an easy-to-follow example of shifting letters in a message. Students can then explore separate pages devoted to well-known encryption methods and developments, including the Caesar cipher, simple substitution, Vigenere and Gronsfeld ciphers, the German Enigma machine, RSA public-key encryption, and PGP. The material combines the history of cryptography with explanations of how various approaches work, making it useful for connecting mathematics, computer science, technology, and history. Some links and technological references reflect the age of this resource, so teachers should preview individual pages and links before assigning them.

tag(s): cryptography (4)

In the Classroom

Use this site as a quick lesson during a history or statistics class, in an attempt to teach students about how some ciphers were solved and how it affected history. Peruse a few of the ciphers as a class on the interactive whiteboard, as a challenge have students try to make or solve one on their own! Students can present their ciphers on the interactive whiteboard, and try to stump their peers!
