4434DataAnalysis App for iPad
http://www.merlot.org/merlot/viewMaterial.htm?id=909175
'DataAnalysis is a general purpose iPad App for the plotting and fitting of all types of data that can be formulated as x,y pairs. The program can be used easily by both students and professionals. It is particularly useful for quick analyses of various types of data by curve fitting, value prediction via a standard curve, and analysis of kinetic data including enzyme kinetics.Data can be entered directly via the keyboard or imported from the Mail App as a text file (.txt), and comma separated value file (.csv). In addition, data can be imported via drag and drop within iTunes. Data files in txt, csv and native formats can be imported directly from Dropbox.After data entry the user has the option to average, baseline correct, and/or normalize the data before plotting and fitting.Plotting of the data is as simple as pressing the Plot button. The axes are autoscaled and the graph is immediately ready to add to a document or presentation. The user has a variety of options to customize the graph by altering the axes, axes labels, graph title, and changing the symbol, its size and color.The data can be fit to a variety of mathematical equations by non-linear regression including simple functions such as linear, 2nd and 3th order polynomials, power, exponential, log functions. Data can also be fit to more complex equations for such processes as radioactive decay, enzyme kinetics, 1st and 2nd order chemical reactions, as well as gaussian, logistics and surge functions. The fit can be overlaid on the data with different line widths, types and thicknesses.For many analytical situations, the data fit can be used as a standard curve to determine the value of unknowns. This analytical procedure is completely automated within DataAnalysis.The program output, graphics and text, can be copied, emailed, or uploaded to Dropbox in a variety of formats including PDF, PNG and TXT. The graphics in PDF format can be edited with programs like Adobe Illustrator™ as objects.DataAnalysis also supports multitasking and printing of input data as well as all forms of output.DataAnalysis has built in tool tips, comprehensive web based instructions and how-to videos available via the Help Menu.'This is a free appProbability of Compound Events (StAIR Project)
http://www.merlot.org/merlot/viewMaterial.htm?id=682700
This is a Stand Alone Instructional Resource project, for the subject of Algebra 1. This StAIR is done through PowerPoint 2010 and covers the topic of Probability…mostly probability of compound events. The point of this stair is that students can work their way through it on their own. The goal of this module is for students to master the concept on how to find the probability of compound events and review their knowledge on experimental and theoretical probability. Students review examples, vocabulary, watch videos, take mini quizzes, etc.IXL

Math is about so much more than just numbers—so, IXL is too! We approach each math concept from all angles, offering visual representations, word problems, interactive activities, and more. With an abundance of math problems for every learning style, students can't help but build lasting skills and confidence.Multiplication and Division of Fractions
http://www.merlot.org/merlot/viewMaterial.htm?id=532438
The lesson provides a real-world application for multiplying and dividing improper fractions and mixed numbers. The scenario is situated in the context of nutritional serving size. The lesson was intended for the use of review and reteaching with students. The lesson includes an assessment activity involving students applying multiplication and division of fractiosn to create a menu for a party identifying number of servings and total required amounts.

A+Click Math Self-study Tests and Skill Assessment for Grade 1 to Grade 12. It includes more than 1000 challenging problems and answers and tons of illustrations. The practice tests adapt to student ability. This website has a graduated set of problems, starting from very simple, to quite difficult. To progress to a new level, you have to answer five consecutive questions correctly. The questions are appropriate to elementary students; almost any second grader could answer the easiest. This is a good assessment test without being insulting or frustrating.James Peirce WTF Project
