Please direct all inquiries to [email protected]. This three-minute video segment was taken from a summer mathematics class in Michigan for rising fifth graders. In the video, students are discussing a "warm up problem" focused on identifying fractions as points on a number line. The correct answer to the particular problem being discussed is 1/3, and the target explanation would draw on the notions of the whole (the interval from 0 to 1), equal partitions of that whole, naming one part, and naming the number of equal parts. Aniyah shares her solution of 1/7 and other students –Toni, Lakeya, and Dante – ask her questions about her solution and her thinking. The video ends just before the class begins discussing this and other solutions.http://deepblue.lib.umich.edu/bitstream/2027.42/134321/1/naming-one-third-on-the-number-line.movhttp://deepblue.lib.umich.edu/bitstream/2027.42/134321/2/naming-one-third-on-the-number-line_texttrack.srthttp://deepblue.lib.umich.edu/bitstream/2027.42/134321/3/naming-one-third-on-the-number-line_context.pdfhttp://deepblue.lib.umich.edu/bitstream/2027.42/134321/4/naming-one-third-on-the-number-line_transcript.pdfDescription of naming-one-third-on-the-number-line.mov : Primary asset: Streaming video, "Naming One-Third on the Number Line"Description of naming-one-third-on-the-number-line_texttrack.srt : Subtitles for video, "Naming One-Third on the Number Line" (to be integrated within KMC)Description of naming-one-third-on-the-number-line_context.pdf : Background and context for video, "Naming One-Third on the Number Line"Description of naming-one-third-on-the-number-line_transcript.pdf : Transcript for video, "Naming One-Third on the Number Line
