Domain - Measurement and Data
Cluster - Represent and interpret data.
[2.MD.D.9] - Generate measurement data by measuring lengths of several objects to the nearest whole unit, or by making repeated measurements of the same object. Organize and record the data on a line plot (dot plot) where the horizontal scale is marked off in whole-number units.
- Line plot
A method of visually displaying a distribution of data values where each data value is shown as a dot or mark above a number line. (Also known as a dot plot.) - Whole numbers
The numbers 0, 1, 2, 3,...
[2.MD.B.6] -
Represent whole numbers as lengths from 0 on a number line diagram with equally spaced points corresponding to the numbers 0, 1, 2, …, and represent whole-number sums and differences within 100 on a number line diagram.
[2.PS.3.1] -
Design and conduct an experiment to show the effects of friction on the relative temperature and speed of objects that rub against each other.
Clarification Statements: Examples could include an object sliding on rough vs. smooth surfaces; Observations of temperature and speed should be qualitative.
[2.ETS.1.3] -
Analyze data from tests of two objects designed to solve the same design problem to compare the strengths and weaknesses of how each object performs.* Clarification Statements: Data can include observations and be either qualitative or quantitative; Examples can include how different objects insulate cold water or how different types of grocery bags perform.
