Just in time for test preparation, ExploreLearning has published a new set of math lesson materials for the following Gizmos:
Simplifying Radical Expressions – Activity A
Simplifying Trigonometric Expressions
Sum and Difference Identities for Sine and Cosine
These 3 Gizmos help students with some fairly advanced topics. Unlike most Gizmos, these are very procedure-focused rather than exploratory. We ask students to work through the steps of a problem, one-by-one, with careful feedback given for any incorrect choices. Each Gizmo will always start with the same 2 problems (which are addressed specifically in the Lesson Materials), and then are randomized after that, to allow for nearly unlimited practice.
As usual, each set of updated Lesson Materials includes 4 documents (Student Exploration sheet, SE Answer Key, Teacher Guide, and Vocabulary sheet), all of which are available as a .doc or a .pdf. (Note: You will need to be logged in to see all the documents.) These replace the older html Exploration Guides.
Lesson Materials are terrific when used to direct whole class intruction/interaction or as individual work with students at computers.
