Students divide the area on a geoboard into halves, fourths, and eighths and compare various-shaped fourths to show they are the same size. They divide dot paper rectangles into thirds, sixths, and twelfths and make designs by coloring in specified fractions of the area. Students make decks of fraction cards and play games with the cards to practice finding equivalent fractions and ordering fractions. Students use some tools to define questions, and to record, represent, and analyze simple data sets about familiar situations. Then they organize the data in rough draft and presentation graphs.
Students describe what seems to be typical for a set of data and are introduced to the median.
As a final project, students divide into small research teams and investigate a question about sleep. Students add and subtract decimal numbers and numbers in the hundreds and thousands. Students solve problems related to everyday uses of money. They investigate distances in miles and tenths of a mile and use a map of their city or town to plan a tour of the area. Students discuss strategies for combining and comparing larger numbers, and they plan a trip around the United States of no more than 10,000 miles.
