In this interactive exercise, learners review definitions of 26 terms and then test their knowledge in a matching exercise. Only six terms are included in the quiz; however, if the learner clicks “Restart,” more terms appear in random order.
In this screencast, students read about the basic organization and structure of the periodic table of elements. Students identify elements as belonging to a group, a period, or neither.
Learning About Multiple Intelligences in the Land of Oz (Screencast)
In this screencast, students read about the seven types of intelligence identified by psychologist Dr. Howard Gardner. They then review the type(s) of intelligence of each character in the Land of Oz.
In this learning activity you'll apply chunking to memory formation and retrieval. You'll test your ability to memorize a series of numbers with and without the chunking method.
In this interactive object, learners read an explanation of the electrodes used for welding with the GMAW and FCAW processes. In two matching exercises, students test their knowledge of classification and specification numbers.
In this fourth part in a series, learners follow the steps of the “mathemagician” to examine three numerical curiosities: Be a Psychic by Predicting Birthdays, Predict a Card with Mind Reading, and Predict the Three Die Values Your Opponent Has Rolled. Learners will also study palindromic numbers and look at two alphametric puzzles.
Learners solve word problems involving basic mechanical principles such as torque, horsepower, work, and power. Students who have problems with a particular word problem may try it again with a different set of numbers.
Recreational Mathematics: Palindromes in Mathematics and the Search for Patterns
Users study a chart containing numbers 1 to 99 and look for trivial palindromes as well as double and triple iteration palindromes. The reverse and add technique is demonstrated.
Learners are introduced to the binary-coded decimal, a common way of encoding decimal digits in computing and electronic systems. A brief quiz completes the activity.
