Notes for teachers

• Context: This lesson will make the students understand the concept of Volume of Cubes through a real-life application.
• The teacher must give a demonstration on how to measure dimensions of a cube using a cubic box or other objects then show how to compute its volume.
• Students will make an origami of cube then create an output made of series of cubes.

List of Materials

​

Ruler

Real-life objects (cubic object) inside the room like the rubiks cube, tissue box, legos, etc.

Standards

7.RI.3 Analyze the interactions between individuals, events, and ideas in a text (e.g., how ideas influence individuals or events, or how individuals influence ideas or events).

7.SL.5 Include multimedia components and visual displays in presentations to clarify claims and findings and emphasize salient points.

7.RI.2 Determine two or more central ideas in a text and analyze their development over the course of the text; provide an objective summary of the text.

6.G.A Solve mathematical problems and problems in real-world context involving area, surface area, and volume.

Objectives:

• Today we will learn the concept of the volume of cubes using real-life objects.
• Today we will learn about the formula used to compute the volume of cubes.
• Today we will appreciate how geometry relates to real-life.

NOTES for the TEACHER:

​

• Use the figure at the right or a similar object that represents a Cube available in your room.
• Demonstrate how to find the dimensions of the cube by counting first the cubic units that made up the cube then measure it using a ruler or other measuring tool to compare its volume.
• Using the dimensions of the cube, show to the students the step-by-step process of computing the volume of the cube.
• You can also ask a student to measure the cube for participation.

CUBE ORIGAMI

• Teach the students how to create a cube using colored papers through ORIGAMI. The link is attached in the next slide for everyone to follow.
• Divide the class in 4-5 groups depending on your class size to create one output out of paper cubes.
• After making 1 cube, ask them to compute for its volume and record it.
• Each group must create as many cubes as possible for them to build something using all of their cubes.
• They must compute the total volume of what they built.

Assessment

• Teach the students how to create a cube.
• Divide the class in 4-5 groups depending on your class size to create one output out of paper cubes.
• After making 1 cube, ask them to compute for its volume and record it.
• Each group must create as many cubes as possible for them to build something using all of their cubes.
• They must compute the total volume of what they built.

Differentiation

Worksheets and additional lectures will be provided for those students who are still confused of the lesson. Online activities will also be given for the mastery of the topic.

Remediation

Extension/Enrichment

Allow the students to give their feedbacks about the activity. Ask them how did they feel about the task and how can they use it in the future. This will serve as an exit ticket for the class.
