Maria Korosis Dr. Moore EDUC 325 February 21, 2011 Assignments “Bar Chart” The manipulative I chose to review was the “bar chart.” This type of manipulative is used to introduce users to the idea of visual representation. There can be as many as 12 columns and 20 cells. There are some limits and restrictions with color and size, however. This manipulative is useful in letting students categorize collections of familiar objects. Once a collection has been categorized, they can be separated into sub-categories and so forth. Students can then label the bar chart accordingly. “Algorithmic Discovery with Venn Diagrams”  This type of lesson helps students learn about algorithms through Venn Diagrams and Box Plots. By the end of the lesson, students will be able to learn how to solve algorithms and the thinking behind the reasoning. By using the Venn Diagram, students will be able to compare and contrast (which involves some reading and writing in the curriculum) the differences in the approaches to solving the problems. ** __Video Viewing: __ ** I watched a video by Kat, and I would definitely highlight standard A-2.5 because it says “I can record and explain math ideas using math vocabulary (e.g., numbers, symbols, pictures, charts, tables, diagrams, graphs, arrays, and equal sharing models).” I think this is important because students need to be able to solve problems and understand the material, but they also need to be able to explain how they came to their reasoning and came to their conclusions and got their answers to a problem.  I also watched a video that explained the root words of many mathematical terms. I would highlight standard B-1.5 because it explains that students should be able to represent numbers with words which is very true—especially with geometry when students are learning about different shapes. Knowing the root words to those shapes can help students learn them more easily.  The last video I watched explained ratios, percentages, and decimals. The standard I would emphasize is B-6.5 because it explains that students should be able to read bigger decimals. When converting between decimals, fractions, and percentages, bigger conversions need to be made and bigger decimal numbers need to be read. It is very important for students to know how to do this when moving from 5th grade into middle school math.
