ALEX Lesson Plans Subject: Mathematics (9 - 12) Title: Exponents and Division Description: This activity will introduce the exponent and division rule, the zero exponent rule, and the negative exponent rule.  Students will make a human fraction to discover the division rule for exponents.  The lesson will also introduce various interactive sites for reviewing exponent rules.This lesson plan was created as a result of the Girls Engaged in Math and Science University, GEMS-U Project.Subject: Arts Education (7 - 12), or Mathematics (5 - 12), or Technology Education (9 - 12) Title: Just the facts! Exploring Order of Operations and Properties of Real Numbers Description: Students use their imagination while learning the importance of 'Order of Operations' and 'Properties of Real Numbers'. This lesson incorporates class discussions, wiki and/or online discussion threads (free at www.wikispace.com and/or quicktopic.com), art and puzzles.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.Subject: Mathematics (7 - 12) Title: Calendar Fun Operations Description: This activity is designed to help students evaluate numerical expressions by using order of operations. The students will be provided a calendar for the current month of the year. Students will then be provided with a worksheet that contains 30 expressions and a different symbol for each expression. The students will manually calculate each expression using order of operations. Once the numerical value has been discovered for each expression, the symbol next to the expression will be drawn on the calendar for that date. This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.Subject: Mathematics (9 - 12), or Science (9 - 12) Title: Writing Word Equations Description: The students will learn to write word and formula equations. We will watch a web video about chemical equations. We will then complete the science in motion lab “The Color of Chemistry”. The students will also be required to write word and formula equations.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.Subject: Mathematics (9 - 12), or Technology Education (9 - 12) Title: You Mean ANYTHING To The Zero Power Is One? Description: This lesson is a technology-based project to reinforce concepts related to the Exponential Function. It can be used in conjunction with any textbook practice set. Construction of computer models of several Exponential Functions will promote meaningful learning rather than memorization. Thinkfinity Lesson Plans Subject: MathematicsTitle: Strong Arm Iteration      Add Bookmark Description: This reproducible worksheet, from an Illuminations lesson, guides students as they take a three-digit number, cube its digits and add them. They do the same with the sum and continue the process until they notice a pattern.Thinkfinity Partner: IlluminationsGrade Span: 6,7,8,9,10,11,12Subject: MathematicsTitle: Exact Ratio      Add Bookmark Description: This reproducible activity sheet, from an Illuminations lesson, features a series of questions pertaining to exact ratios and geometric sequences. In the lesson, students measure lengths on stringed musical instruments and discuss how the placement of frets on a fretted instrument is determined by a geometric sequence.Thinkfinity Partner: IlluminationsGrade Span: 9,10,11,12Subject: MathematicsTitle: Stacking Squares      Add Bookmark Description: This Illuminations lesson prompts students to explore ways of arranging squares to represent equivalences involving square- and cube-roots. Students explanations and representations (with their various ways of finding these roots) form the basis for further work with radicals.Thinkfinity Partner: IlluminationsGrade Span: 9,10,11,12
