Lesson Plan: Mass (40 minutes)

Learning Area: Mathematics
Lesson Topic: Mass
Year Level: 5
Overall Duration: 40 minutes

Curriculum Links:

• AC9M5M03: Measure, compare, and calculate the mass of various objects using metric units.

Objectives:
By the end of this lesson, students will be able to:

• Estimate and measure the mass of different objects using appropriate metric units.
• Arrange objects by mass from lightest to heaviest.
• Apply their understanding in a practical group challenge.

Materials:

1. Digital kitchen scales
2. Various objects (e.g., apples, toys, cans)
3. Mystery bag for mass guessing game

Learning Experience Plan:

1. Introduction (5 minutes):
• Introduction to Mass: Show various objects and ask students to estimate their mass.
• Explain the difference between Mass and Weight

Mass is a measure of how much an object resists a force. A object with more Mass contains more matter (solid/liquid/gas/plasma) than one with smaller mass. Measured in kg (kilograms 1000grams).

Different to weight which is the effect of gravity on Mass and is measured in Newtons and differs because of the force of gravity

• Video Tutorial: Play a short tutorial from "Math with Mr. J" to introduce mass.
1. Hands-On Activity: Estimating Mass (15 minutes):
• Group Activity: Provide groups with objects and digital scales to estimate and measure mass, recording the results.
2. Interactive Game: Mass Relay Race (10 minutes):
• Game Setup: Create a relay where students arrange objects by mass, competing in teams.
• Depending on time let students estimate the mass of hidden objects in packets.
3. Workbook Practice (5 minutes demo  + 40 minute workbook )
• Workbook:  Students Complete exercises comparing mass and calculating combined mass show Youtube videos to reinforce concepts
4. Conclusion (5 minutes):
• Reflection: Ask students what surprised them about the mass. Each student writes an exit ticket with an estimated mass of an object.

Challenge question. Which has greater Mass Ocean water or Rain water? Why?

Differentiation:

• For advanced learners: Use larger or irregular objects for estimating.
• For students needing support they may use Google  to find  a reference chart for common mass measures.

Assessment:

• Formative: Observe group activities.
• Summative: Review workbook exercises.

Reflection:

• Were students engaged in estimating and measuring mass?
• Did the interactive games reinforce the concept effectively?
