Students practice working with the metric system. Students use a metric ruler to measure and record lengths of group member's smiles, and graph their results. Students find the sum of all the smiles.

Students take measurements using a metric ruler, find a sum of multiple metric measurements, and use a histogram to graph their results.

Learners accurately use a metric ruler to measure length. They find a sum of multiple metric measurements.

Students practice working with the metric system by measuring and recording the lengths of their smiles.

Students measure the length of student smiles and then record, order and graph their results.

Students explore how to use a metric ruler to measure length, accurately read and record measurements taken in centimeters (cm) and millimeters (mm), and collect and analyze data using a stem and leaf.

Students explore the concept of ratios. In this ratios lesson, students use matchbox cars and models of spaceships to explore ratios. Students determine scale for the above mentioned objects in this lecture style lesson.

In this lesson plan site, young scholars will learn how to use a metric ruler to measure length, accurately read and record measurements taken in centimeters and millimeters, and collect and analyze data using a stem and leaf.
