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.
