lluminations is a website from the National Council of Teachers of Mathematics.  You'll find terrific lesson plans for pre-K through high school. This particular one uses buttons to teach the concepts of before, after, and between for lower elementary children. It also can be used as a review of ordinal and cardinal numbers. The lesson begins with students singing and playing London Bridge practicing using positional words. You’ll need to provide bags of buttons for the students to place on a 10 Strip activity sheet which you can print off from the site. Lots of suggestions are given on different ways to use the buttons for counting, and also for color recognition.

Here's a great interactive game
from the National Council of Teachers of Mathematics. It's a great way for students to work with fractions by combining like pairs. Students move markers across the board based on the cards that are flipped over. The goal is to move all the markers from one side to the other using the fewest amount of cards. The instructions are clear and offer good examples. The exploration section asks questions about what the player discovers after playing several rounds. You can also find a lesson plan for using a fractional clothesline for enrichment.

Got a mole on your back causing you the inability to understand stoichiometry?  Then click on this site to enable a better understanding of Avogadro's Number (6.02 x 10^23). Watch this brief video to grasp general information about the mole and how its use is. Included are the text of the movie to run off and practice questions. 

SOS Math is a great site that offers quite a bit mathematical enrichment questions. Solving Equations is a must have in your favorite file! If you need a quick glance concerning algebraic problems or solutions, you'll find each step carefully laid out. You can then work through another example or ask for more problems to solve, each of which will have the solution explained.  Practice solving linear equations, equations containing radicals, equations with absolute values, quadratic equations, equations with fractions, exponential equations, logarithmic equations, and trigonometric equations is included.

Statistics can be an intimidating field of study. One area that needs a bit of enrichment is descriptive statistics which shows central tendency when summarizing hundreds of pieces of data. Learn how to figure the mean, mode, and median when locating central tendency. Here you will also learn about range, and how it is calculated to find variation in the sample. Practice what you know by clicking on the link to a BBC game.  Finally check out the review questions to ensure you've mastered the content.

Not quite understanding linear functions? Here's a website that utilizes a simple process to explain a more complicated process simply. To begin, click on the “learner” tab so you understand you determine the function by looking for patterns in the outputs.  Once you glace the examples, the activity will be a breeze.  If you you are still uncertain the “Help” tab will walk you through some concrete examples for using the number cruncher machine.  The “Instructor” tab indicates how to use this activity to teach the properties of linear function and problem solving skills.   

Robin Hood challenges you to test your knowledge of doubles as you click on the correct answer on the target. The questions and answers all involve numbers beyond ten. If you are correct, you get a three-trumpet salute. If you make a mistake, the music lets you know, and you can keep trying until you find the correct answer. This is a good game for reviewing doubles and also gives good practice in using the computer mouse. -teach and learning

Written by math educator Cynthia Lanius and hosted by Rice University, these lessons offer games, activities, and practice on a number of math concepts for students in grades K-4, 5-8, and 9-12. Topics range from counting to calculus, from fractions to graphing. Some lessons are in Spanish as well as English, and larger sections contain a page of notes for teachers. -tech and learning
