Summarize numeric data with numerical summaries, including the mean and median (measures of center) and the range (a measure of spread). Mean, median and range of catch distances; this is an early start on a Grade 6 outcome, and the interquartile range is not covered.
The Texas Essential Knowledge and Skills (TEKS) for Mathematics outcome 6.12(C) (Measurement and data) for Grade 6 says: “Summarize numeric data with numerical summaries, including the mean and median (measures of center) and the range (a measure of spread). Mean, median and range of catch distances; this is an early start on a Grade 6 outcome, and the interquartile range is not covered.” These 2 Fieldbook units teach it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: Texas Essential Knowledge and Skills (TEKS) for Mathematics.
Measure It: Length, Time and Mass in the Real World Grade 3
Whose foot is the right ruler? How long is a minute, really? Is a kilogram of feathers lighter than a kilogram of rocks? Four lessons where students measure length, time and mass with real tools, then use their own data to settle an argument.
- Whose foot is the right ruler? 50–60 min
Teams measure the same taped line on the floor in heel-to-toe steps and get different answers, then measure it again with metre sticks and all agree. Students explain why the world needs standard units, and measure their own feet to build a class line plot.
- How long is a minute, really? 50–60 min
With eyes closed, students raise a hand when they think one minute has passed while a partner times them to the second. The class builds a line plot of its guesses, tries again with a counting strategy, then solves elapsed-time problems taken from its own school day.
- Which weighs more, a kilogram of feathers or a kilogram of rocks? 55–60 min
Teams build a coat-hanger balance to compare classroom objects, estimate masses in grams and check them on a kitchen scale, then heft three bags that look very different but may or may not have the same mass. Students explain why size doesn't tell you mass.
- Can we design the best paper airplane? 55–60 min
Teams fold a classic dart and their own design, fly each one five times from the same line, and measure every flight with a tape measure. Students find the middle value for each design, plot the class results, and use the data to argue which design really flies farther.
Data Detectives Grade 5
How fast are our reflexes? Which graph is telling the truth? Do taller people really have bigger hands? Three lessons where students collect their own measurements and find out what numbers can and can't tell you.
- How fast are our reaction times? 50–60 min
Partners drop a ruler and catch it, five times with their writing hand and five times with the other hand. Students find the mean, median and range of their own catches and the class's, then decide whether our writing hand really is quicker.
- Which graph tells the truth? 50–60 min
Teams take the class's reaction-time results and draw two bar graphs of exactly the same numbers: one honest, one built to exaggerate. Then they hunt for the same tricks in a set of sneaky graphs and fix an advertisement's chart.
- Do taller people have bigger hands? 50–60 min
Students measure height and hand span, plot every person as one point on a scatter plot, and draw a trend line by eye. They decide whether taller people tend to have bigger hands, and learn the difference between a trend and a rule.
