Measurement A Mini-Unit for Kindergartners
Virginia Standards of Learning – Measurement Standards addressed in this unit K.8 The student will identify the instruments used to measure length (ruler), weight (scale)… and temperature (thermometer). All students should • Identify an appropriate measuring tool for a given unit of measure.

The student will use problem solving, mathematical communication, mathematical reasoning, connections, and representations to • Identify a ruler as an instrument to measure length. • Identify different types of scales as instruments to measure weight. • Identify different types of thermometers as instruments used to measure temperature. K.10 The student will compare two objects or events, using direct comparisons or nonstandard units of measure, according to one or more of the following attributes: length (shorter, longer), height (taller, shorter), weight (heavier, lighter), temperature (hotter, colder). Examples of nonstandard units include foot length, hand span, new pencil, paper clip, block. All students should • • Compare and order objects according to their attributes. Develop an understanding of measuring with nonstandard and standard units of measure.

The student will use problem solving, mathematical communication, mathematical reasoning, connections, and representations to • Compare and describe lengths of two objects (as shorter or longer), using direct comparison or nonstandard units of measure (e.g., foot length, hand span, new pencil, paper clip, block). • Compare and describe heights of two objects (as taller or shorter), using direct comparison or nonstandard units of measure (e.g., book, hand span, new pencil, paper clip, block). • Compare and describe weights of two objects (as heavier or lighter), using direct comparison or nonstandard units of measure (e.g., book, cubes, new pencil, paper clip, block). • Compare and describe temperatures of two objects or environment (as hotter or colder), using direct comparison. Concepts: • Measurement

Description Comparison

Principles: • We use measurement to describe things. • We use measurement to compare different things. • We use measurement to help us make decisions. • Standard units of measurement help us communicate with others. Objectives As a result of this lesson, students will KNOW… • … the instruments used to measure length (ruler), height (yard stick or meter stick), weight (scale)… and temperature (thermometer) • … attributes of comparison for length (shorter, longer), height (taller, shorter), weight (heavier, lighter), and temperature (hotter, colder) • …the difference between nonstandard and standard units of measure • …examples of both nonstandard and standard units of measure As a result of this lesson, students will UNDERSTAND… • …that we use measurement to describe things • …that we use measurement to compare different things • …that we use measurement to help us make decisions. • …that standard units of measurement help us communicate with others As a result of this lesson, students will BE ABLE TO … • …use problem solving, mathematical communication, mathematical reasoning, connections, and representations to… o …compare objects in terms of standard and nonstandard units of measurement. o …describe the benefits of using nonstandard and standard units of measurement o …identify an appropriate measuring tool for a given unit of measure o …compare and order objects according to their attributes. Materials Needed: • Children’s books o How Big is a Foot? by Junko Morimuto o Inch by Inch, by Leo Lionni o Ten Beads Tall, by Pam Adams • Individual square-inch units – class set • Rulers (Primary class set – attached – as well as several foot-long rulers and a yard stick or large demonstration ruler) • 1 balance scale and weights • 1 bathroom scale • Thermometers (several)

Pre-Assessment Place students into homogeneous groups of 4-5 according to their readiness in terms of their skill in the...
