# Measuring Is So Much Fun!

In this active lesson, your students will love learning how to use a ruler as they go on a measurement scavenger hunt in the classroom! It can be used as a stand-alone or support lesson for the Wonderful World of Worms lesson plan.
This lesson can be used as a pre-lesson for the Wonderful World of Worms lesson plan.

Students will be able to measure and compare the lengths of two objects.

##### Language

Students will be able to explain how to compare the length of two objects.

(2 minutes)
• Gather students together for the lesson.
• Hold up a ruler and say, "Does anyone know what this is called?"
• Explain that this is a ruler (invite students to repeat the word after you) and it is a tool used to measure or find out the length of something.
(5 minutes)
• Explain the focus of the lesson by saying, "Today we are going to be comparing things to find out if they are shorter, longer, or the same size. Comparing means looking to see how things are different or the same."
• Display two items you collected and show them to the class (e.g., a small toy car and a bigger toy car) and model how to measure the items with your ruler. Show your students how to compare the items using the ruler to see if one is bigger or smaller, or if they are the same size.
• Display the vocabulary cards on the board for reference.
• Model how to use the new vocabulary words when comparing objects by saying something like, "The red car is shorter than the ruler. The blue car is longer than the ruler. The red car is smaller than the blue car."
• Hold up another pair of objects. Ask, "Which one is bigger?" and have the class turn and talk to share with a partner.
(5 minutes)
• Compare the two items as a class and invite the students to share ideas of how they know if something is bigger/smaller/same size.
• Explain that students will now get to compare objects with a partner.
• Pair students with a partner. Then pass out a ruler and one object to each student (e.g., crayons, markers, pencils).
• Have students use their rulers to practice comparing with their partner to see if they are bigger, smaller, or the same size.
• Call the class back together and invite students to share out their findings. Provide support for students to use mathematical vocabulary to describe their findings such as: "bigger," "smaller," "same."
(15 minutes)
• Explain that now students will get even more practice comparing objects!
• Display the Measuring Scavenger Hunt worksheet and go over the instructions.
• Have students work with a partner to find, compare, and record their objects.

Beginning

• Work in a small teacher-led group to measure additional objects with support.
• Provide sentence frames for students to practice using the vocabulary, e.g., "This __ __ __ __ is bigger/smaller/same as __ __ __ __ because __ __ __ __."

Intermediate

• Encourage students to find and measure items of a specific length (e.g., 6 inches), and compare to other objects. Have students practice describing items using sentence frames: "The __ __ __ __ is __ __ __ __ inches long. It is __ __ __ __ inches longer/shorter than __ __ __ __."
(5 minutes)
• Circulate around the room taking notes, capturing student conversations, and taking pictures in order to create a process board of student learning.
• Collect work samples and assess if students were able to accurately compare objects.
(3 minutes)
• Gather the class back together.
• Ask students to think-pair-share with a new partner to compare their work. Did they find two things that were the same size? How did they know?
• Reflect back to the class some of your observations about their process and strategies for measuring.
