621 Translations, Reflections, and Rotations Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 6–8 Professional Commentary: This lesson provides an introduction to geometric transformations -- reflections, rotations, translations, and glide reflections. The accompanying applet allows students to perform a transformation and then analyze the relationship between the original object and the resulting image.... 622 Introduction to Fractals: Infinity, Self-Similarity and Recursion Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 8–12 Professional Commentary: This introduction to fractals provides links to five applets that illustrate the infinte, self-similar, recursive processes characteristic of fractals. Worksheets that accompany each applet help students analyze these complex processes.... 623 Introduction to Fractals: Geometric Fractals Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 8–12 Professional Commentary: This lesson follows an introduction to fractals in a lesson on Infinity, Self-Similarity, and Recursion. In this follow-up lesson, students work with applets that demonstrate Sierpinski's Triangle and Sierpinski's Carpet to look for patterns and limiting values in two-dimensional fractals....

A Racing Game applet is included, along with discussion questions and suggestions for guided and independent practice.... 626 Fire!, Probability, and Chaos Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 6–8 Professional Commentary: Students use an applet to see what percentage of a forest is destroyed given different probabilities of a tree catching fire. To understand how the applet works, students trace the spread of a forest fire by hand on grid paper.... 627 Histograms and Bar Graphs Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 6–8 Professional Commentary: Students manipulate the vertical scale on a bar graph applet and the horizontal interval on a histogram applet to see how the appearance of a graph can change even though the data remain the same. They study prepared examples to see how information can be hidden or revealed by different representations of the data.... Resource Type: Instructional Resource -- Promising Practice Discipline: Mathematics Ohio Standards Alignment: Grades 6–8 Professional Commentary: This lesson leads students step by step through the construction of a box-and-whiskers plot, first by hand and then on an applet. Students can practice with data that are provided or can collect and enter their own data into the applet.... 629 Focusing Reader Response Through Vocabulary Analysis Resource Type: Instructional Resource -- Promising Practice Discipline: English Language Arts Ohio Standards Alignment: Grades 4–7 Professional Commentary: After reading and analyzing a novel or another piece of literature, students compile a list of words associated with the text they have read. This list represents a list of words ranging from details about the plot to feelings about a character.... 630 Developing Reading Plans to Support Independent Reading Resource Type: Instructional Resource -- Promising Practice Discipline: English Language Arts Ohio Standards Alignment: Grades 6–8 Professional Commentary: In this lesson, students brainstorm texts that they have read and map their choices using the Graphic Map, looking for patterns connecting those that they enjoyed the most. Once they've analyzed their past readings, students complete a reading plan, a simple wish list of books they hope to read in the future....
