• Lesson Plan
• Subject: Math
• Driving Question: How do we measure objects?
• Pedagogical Method: Kinesthetic Learning
• Duration: 50 minutes
• Delivery Method: Messenger Applications
• ### Purpose

Students will be able to identify different forms of measurement and measure objects found in their daily life.

• ### Before you start

● Materials: laptops/tablets/Mobile phones
Also find attached the necessary resources in the Files section

• ### Objectives

• Estimate the lengths
• Measure the lengths using the millimeter and the centimeter
• Determine the relationship between the kilometer, meter, centimeter, and millimeter

Keywords: ruler, lines, kilometer, meter, centimeter, millimeter

• ### Prior Knowledge

• Students must understand the concept of measurement being a number that shows the size or amount of something.
• Students must know how to draw a line.

• ### Warming Up (10 minutes)

Ask students to compare their height to the height of their brothers or parents at home.

Have them go on a scavenger hunt and try to collect things in the house that are of the same length. Then, have them determine the shortest and longest thing in their room. Have students share by sending voice or text messages and by taking and sending pictures of the items collected.

• ### Learning Activity 1 (15 minutes)

Then send one of the following videos depending on your students’ grade level.

1. For grade 1, send Video 1 to understand the concept of length and measurement
2. For grade 2, send Video 2 to distinguish between the units of measurement of length, and how to use a ruler to measure length (centimeters, millimeters).
3. For grade 3, send Video 3 to understand how to convert from m to cm to mm.

To check for understanding, have students send voice messages reflecting on how their learning shaped up. They will use the sentence starters, “I used to think….Now I know….”

• ### Learning Activity 2 (20 minutes)

For grade 1: Have students use cubes to measure some small things such as a pen, spoon,...

Then, have students trace their hands and feet on a paper and measure using snap cubes or similar items. Have them send pictures of their work.

For grades 2 and 3: Have students use a ruler to measure some small things in the house, such as a book, a pen, or a fork, and a measuring tape to measure larger things, such as a door or window. They can observe the car meter with their parents to measure distances in kilometers, or use google maps to measure the distance between their home and other villages (Km). Have them send pictures of their work or voice or text messages to share their findings.

To check for understanding, you have two options. Either send Link 1 and have students share their scores with you, or have students choose an item at home and measure it using the ruler. Have them take pictures of their measurements and share them with you.

• ### Wrap-Up (5 minutes)

Have a student use Link 2 to measure some lines, and solve reflection questions. Like: How long do you estimate this objective is? Was your estimation close to the exact measurement? What do you notice about the measurement?

For homework, there are two option. One, have students observe the measurement of length using a ruler and distinguish between centimeters and millimeters (Link 7). Then, have them estimate length (Link 3) and convert to cm, m, or mm (Link 6).

Two, have students find 3 items at home they wish to measure and tabulate their measurements in an organizer (Worksheet 1). They can challenge themselves by finding the connection between cm and mm.
