$hero$ Building a Garden Fence In this activity, students will use basic concepts of perimeter and area to investigate a classic problem situation requiring maximization. They must decide how to build a garden fence to enclose the largest possible area. Standards Textbook	TI-84 series	Download5,460
$step2$ Changing Before My Eyes In this activity, students will discover how pictures formed by graphing ordered pairs can be stretched (and shrunk) by multiplying (and dividing) the coordinates. Standards Textbook	TI-84 series	Download379
$step1$ Comparing Area of Rectangles In this activity, students discover the relationship between a change in the dimensions of a rectangle and the change in the corresponding area. Standards Textbook	TI-84 series	Download286
$step2$ Making Triangles In this activity, students will investigate properties of triangles, classify the various types of triangles, and determine if specific side lengths will make a triangle or not. Standards Textbook	TI-84 series	Download276
$step1$ Mirror, Mirror, on the Graph In this activity, students review basic geometry vocabulary while investigating reflections on a coordinate grid. Standards Textbook	TI-84 series	Download223
$step2$ Move it In this activity, students investigate transformation, slides and scaling, of a triangle using lists. They will add, subtract and multiply numbers to the list and describe the changes that have occurred. Students are to make the connection between changing the x- or y-values and the transformation.

$hero$ Transforming Fish In this activity, students will discover how pictures formed by graphing ordered pairs can be stretched (and shrunk) by multiplying (and dividing) the coordinates. Standards Textbook	TI-84 series	Download1,718
$step3$ Vertical Angles In this activity, students visualize and explore the angles that are formed when two lines intersect. By measuring angles formed by intersecting lines, they enhance their understanding of vertical angles, supplementary angles, and a linear pair. Standards Textbook	TI-84 series	Download432
