Other Learning Resources PROCEDURE Reviewing previous Lesson or presenting new lesson

Establishing and achieving the purpose for the lesson.

Review on how to find the area of a rectangle, square and parallelogram then give some examples. Review the formula, give examples, then give exercises. Dino saw a picture of an interesting building in a postcard. He was interested to find the area of the parallelogram-shaped façade of the building. He remembered that parallelogram was discussed in their Mathematics class. Help Dino to find the area. Then ask: How can we help Dino?

Have a review on how to find the Perimeter of a regular polygons.

Review on finding the area of plane figures.

Review on finding the area of plane figures.

Present the lesson through ICT presentation to mop out the boundary of knowledge regarding the area. The presentation will commence from the very basic idea of area to establish the understanding of pupils as to what the area means and step by step to more complex and complicated and application on how to derive the area from basic knowledge to

Present this situation to the class: Shapes pervade our lives. All around us are different shapes, each serving its own purpose. Can you imagine a world where objects are of the same shape? How will this world look like? How will this affect our lives?

Review on solving for the perimeter and area of a triangle, a parallelogram, and a trapezoid.

Let the pupils use rubber bands on geoboards to create a triangle, a parallelogram, and a trapezoid. Ask them to record the perimeter and area of each figure.

Discuss the situation with the class.

Group Activity The outputs should be posted and used during the presentation. After all groups have finished, ask a member from each group to discuss their solution.

Group Activity Group the pupils into four groups and give each group a drawing of the figures. The output should be explained and solve on the board and used during the presentation. After all groups have finished, ask a member of each group to report on the output.

Divide the class into five groups and tell them to look for an object corresponding to the shapes studied in the previous lessons. Each group will first make an estimate of the dimensions of the chosen object and then, compute for the area using these estimated dimensions. Then, using an appropriate measuring instrument and unit of measurement, they will get an accurate measurements of these objects and find the area

Let the pupils present the figures formed and discuss how the area and perimeter are obtained. Ask them to give the different ways in finding the area and perimeter.

Group Work Activity

Discussing new concepts and practicing new skills #2.

Finding practical application of concepts and skills in daily living and Evaluating Learning

After the presentations of the group, ask: *How did you find the activity? *Lead the pupils to derive the formula for finding the area of a triangle, parallelogram and trapezoid. Ask pupils to work in the Get Moving, of LM Math Grade4. For more practice, ask them to work on in the Keep Moving of LM Math Grade4.

After the presentations of the groups the pupils have to show their ability in solving the task.

Discuss the relation of the lesson to real life. Do Exercises which aligned to the objective.

After the presentations of the groups, ask: How did you find the activity? How did you go about the task? How did you estimate the area?
