Big Ideas: Rulers can be used to precisely measure the lengths of objects to the nearest whole, half, or quarter of an inch. A line plot can be used to organize and display data.
This lesson builds upon students' knowledge of fractions by focusing on representing ruler measurements. The task requires students to demonstrate their critical thinking skills by having them work with their own pencil measurements. They must represent their data using a line plot. This lesson particularly focuses on whole, half, or quarter inch measurements greater than one inch. This builds toward students' ability to use rulers to measure objects to the nearest eighth of an inch.
Vocabulary: quarter, inch, plot, data, scale
