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. Students explore the ways things change over time and look at ways to represent these changes. Students plant seeds and measure and record plant heights throughout the unit. Students find their own ways to show the changing population of their homes during a 24-hour period.
