In this unit, students begin to describe and measure several attributes of objects, such as length, width, height, and weight. These understandings build the foundation for classification of shapes both 2D and 3D as well as build a basic understanding of the components needed for perimeter and area. Students may struggle with the idea of permanence of an object’s attributes, therefore this unit also addresses the understanding that attributes remain consistent as they move through space.
Key Concepts:
 A single object may have multiple attributes that are measureable. (Lesson 1)
 Objects can be compared based on an attribute they share. (Lesson 5)
 An object’s length remains the same regardless of its position relative to another object. (Lesson 8)
Prior Knowledge Needed:
 Vocabulary: object, attribute, compare (Grade K, Unit 5; K.G.A.2)
 Rote counting and understanding amount (Grade K, Unit 1; K.CC.A.1, K.CC.B.4a)
 Identifying and describing shapes (Grade K, Unit 5; K.G.A.2)
Units on the Horizon:
 Classifying two and threedimensional shapes (Grade K, Unit 11)
 Measuring lengths with nonstandard units (Grade 1, Unit 16)
 Exploring standard units of length (Grade 2, Unit 2)
 Reasoning with shapes and their attributes (Grade 2, Unit 10)
 Estimating and comparing length (Grade 2, Unit 14)
Lessons

Lesson objective: Understand that an object may have multiple attributes that are measurable. Students bring prior knowledge of attributes from K.G.A.1. This prior knowledge is extended to objects and their multiple attributes as students describe how o...

Lesson objective: Practice comparing lengths and heights. This lesson helps to build procedural skills by comparing the attributes of length and height. Length and height is used here because most common objects can be compared by these dimensions. This...

Lesson objective: Apply appropriate techniques for comparing lengths and heights of objects. This lesson provides an opportunity for students to apply their knowledge and understanding of comparing lengths and heights of objects to a reallife situation...

Lesson objective: Compare objects by a single common shared attribute. Students bring prior knowledge of how to identify attributes from Grade K, Unit 08, Lessons 13. This prior knowledge is extended to comparing one attribute at a time as students fin...

Lesson objective: Practice measuring length and height using nonstandard measurement tools. This lesson helps to build procedural skills for measuring with a nonstandard measurement tool. Showing the procedure of measurement (with paper clips) is used...

Lesson objective: Practice measuring weight using a balance scale. This lesson helps to build procedural skills with using a balance to compare weight. A balance is used here because it is a measurement tool which students will be asked to use to make c...

Lesson objective: Gain exposure to using measurement tools for weight. This lesson provides an opportunity for students to apply their knowledge and understanding of comparing the single attribute of weight to a reallife situation. Students are asked t...

Lesson objective: Understand that length is a constant (static) attribute. Students bring prior knowledge of attributes from describing and comparing measurable attributes. This prior knowledge is extended to an understanding that certain attributes do ...

Lesson objective: Practice measuring objects to compare a single attribute regardless of the object’s position. This lesson helps to build fluency with measuring objects with precision. A linking cube ruler is used here because it supports student learn...

Lesson objective: Apply the skill of measuring to a real world problem. This lesson provides an opportunity for students to apply their knowledge and understanding of measuring objects to a reallife situation. Students are asked to help Ron and his pri...
