Graph to compare heights and gender8/31/2023 This is accomplished by students gluing pre-cut rectangles, resembling the measuring blocks students used, onto lined prepared chart paper. As a class activity, create a bar graph that shows all the heights of the students in the class.OVERVIEW: During the course of several days, students will: It works best if you determine in advance which pair of kindergartners will measure the heights of which two older students in each class. A few days in advance, arrange times when your class can visit a second-grade class and a fourth-grade class.It is best if all the recruited adults visit the class at the same time, but if not, schedule over several different days and times. Try to get both men and women, and include yourself. These might be parents, administrators, librarians, janitors or counselors-anyone who can spare a few minutes. A week or two in advance, recruit a dozen or so adults to visit your class and be measured by your students.This way, when students glue down the rectangles, they can line up the pieces along the vertical lines to keep the graphs from leaning or becoming too crooked. Use the wider spacing if your rectangles are the larger size. The vertical lines make it easier for students to glue the rectangles neatly onto the poster board into bar graphs. Draw one vertical line for each student in the class, and write a different student's name at the bottom of each of line. Use a meter stick and pencil to lightly draw vertical lines about every three to four inches across the sheets of poster board.The exact number of rectangles needed depends on the class size. Since construction paper measures 9 x 12-inches, 1 x 3-inche rectangles are easy to mark off and cut (1½ x 4-inch rectangles are also easy, but require more construction paper). It helps to use a paper cutter to make this easier! The exact size does not matter but make them similar in proportion to the building blocks being used and an easy size for students to handle. Prepare about 500 construction paper rectangles, all sized ~1 x 3-inches, for students to use, with glue, to make bar graphs.Create and make copies of a data sheet for each student to use when visiting the other grade classrooms to record the names and heights of a second grader and a fourth grader, and provide space to make tally marks as they measure the older students.Today, you will help me make a large graph of your heights. Graphs are very useful because they let people share or learn about a lot of information in a quick and easy way. Who has heard of a graph? (Listen to student responses.) Where have you seen a graph? How was it used? What did it tell you? I know a way to show all that information in a special type of picture called a graph. Point out the list of student heights that was obtained during that discussion.) (Gather the class together and remind them of the discussion that was held after they measured each other using building blocks. poster board, several sheets, either all one color, or four different colors, one for each age group.15-30 sheets of construction paper (preferably all the same color).medium building blocks, half as long as the long blocks above one for every two students.long building blocks, about 10 inches long one for every two students in the class.Show the measurements by making a line plot, where the horizontal scale is marked off in whole-number units. Generate measurement data by measuring lengths of several objects to the nearest whole unit, or by making repeated measurements of the same object. International Technology and Engineering Educators Association - TechnologyĬompare two numbers between 1 and 10 presented as written numerals. Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit. Solve simple put-together, take-apart, and compare problems using information presented in a bar graph. Organize, represent, and interpret data with up to three categories ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.ĭraw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Describe several measurable attributes of a single object.ĭirectly compare two objects with a measurable attribute in common, to see which object has "more of"/"less of" the attribute, and describe the difference. Describe measurable attributes of objects, such as length or weight.
