Lesson Plan: Standard and Nonstandard Units through PE Activity

Grade: Primary 2

Subject: Mathematics

Duration: 45 minutes

Objective: - Students will understand the concept of standard and nonstandard units of measurement. - Students will be able to differentiate between standard and nonstandard units. - Students will apply their understanding of standard and nonstandard units through a physical education activity.

Materials: - Whiteboard or chart paper - Markers - Measuring tapes - Rulers - Cones or markers for activity setup - Worksheet (link provided below) - Video resources (links provided below)

Introduction (5 minutes): 1. Begin the lesson by asking students if they know what measurement means. 2. Write the word “measurement” on the board and explain that it is the process of finding out how long, tall, heavy, or wide something is. 3. Show students different objects of varying sizes and ask them how they would measure each object. 4. Introduce the terms “standard units” and “nonstandard units” and explain that standard units are fixed and commonly used for measurement, while nonstandard units are objects or body parts used for measurement.

Lesson Outline (10 minutes): 1. Write “Standard Units” and “Nonstandard Units” on the board. 2. Explain that standard units are used to measure things accurately and consistently. Examples include centimeters, meters, and kilograms. 3. Discuss nonstandard units and give examples such as using paperclips, pencils, or hands to measure objects. 4. Show students a ruler and a measuring tape, explaining that these are tools used to measure with standard units. 5. Demonstrate how to measure an object using both standard and nonstandard units.

Questioning (5 minutes): 1. Ask students: - What are standard units? Can you give examples? - What are nonstandard units? Can you give examples? - How do we measure using standard units? - How do we measure using nonstandard units?

Assessment (10 minutes): 1. Divide students into pairs or small groups. 2. Provide each group with a worksheet (link provided below) that includes objects to measure using both standard and nonstandard units. 3. Circulate the classroom, observing and assisting students as they complete the worksheet. 4. Assess their understanding by checking if they correctly use the appropriate units for each measurement.

Differentiation (5 minutes): 1. For students who need additional support, provide them with manipulatives such as cubes or counters to help them visualize the concept of measurement. 2. For students who need a challenge, ask them to measure objects using both standard and nonstandard units simultaneously and compare the results.

Plenary (10 minutes): 1. Gather students together and review the concepts of standard and nonstandard units. 2. Show a video resource (link provided below) that reinforces the lesson’s content. 3. Discuss the video and ask students to share what they learned or found interesting. 4. Summarize the lesson by emphasizing the importance of using the appropriate units for accurate measurement.
