Grade 3 Unit 4 The Wonder of Linear Measurement
In this unit, children explore how to measure the length of objects and distances using standard units. They discover that measurement is not only practical but also a way to describe and compare the world with precision and creativity.
The will:
- Learn to measure in centimetres, meters, inches, and feet.
- Develop strategies to estimate, measure, and compare lengths accurately.
- Solve problems that involve addition, subtraction, multiplication, or division with length.
- Use measurement in hands-on contexts such as building, drawing, and exploring nature.
- Understand why accuracy matters and how different units are best suited for different tasks.
- Discover how humans first created systems of measurement, from using hands and feet to developing rulers and standardized units, and why the desire to measure has always been part of human history.
Children will see that measurement is more than numbers on a ruler—it’s a tool that helps us make sense of space, size, and distance. By exploring its history, they also discover how measurement reflects our human curiosity and creativity across time.
This purchase includes one digital curriculum unit with 15 days of lesson plans and 5 days of flexible projects. This unit will inspire you with beautiful images, clear instructions and exciting project ideas.
And that's not all. You will also gain access to the Wonder Hub, which includes supporting documents, videos, resources, and community.
The Wonder of Linear Measurement
Learning Standards
Concept 1: The development of computational fluency in addition, subtraction, multiplication, and division of whole numbers requires flexible decomposing and composing.
Connection: Your child will spend the weeks of the unit practicing measurement and computation, including estimation.
Concept 2: Regular increases and decreases in patterns can be identified and used to make generalizations.
Connection: Your child will hear about the Imperial and the Metric systems and use these to make generalizations.
Concept 3: Standard units are used to describe, measure, and compare attributes of objects' shapes.
Connection: Your child will learn about the Imperial and Metric measurement systems. Perimeter, area and circumference will be introduced as well.
Language Arts:
Concept: Stories and other texts help us learn about ourselves, our families, and our communities.
Connection: Stories about measurement will get your child thinking about their own life and the things around them.
For your story line, you can keep reading from the Old Testament. On Day 5 you’ll need the story of Noah and the Flood. If the Old Testament is not a match for you it is possible to use Legends. A good resource is Sparkle Stories, original audio for children.
Social Studies:
Concept: People from diverse cultures and societies share some common experiences and aspects of life.
Connection: All stories about measurement will begin with the historical story of it, thereby connecting your child to the world.
