Measuring Area: Objectives

This 26-minute fourth grade math lesson taught students how to calculate area. The teacher began with a story problem about two fields to introduce the concept of area. Students then participated in three activities: 1) using different shapes as area units to pave domains, 2) expressing the area of surfaces in square units, and 3) drawing squares and rectangles with given areas. The objectives were for students to be able to calculate area using specific units, express area in ordinary units like squares, and draw shapes based on area.

Measuring Area

Mathematics, level: 3-5

Subject: Math Teacher: Mariam Santina


Topic: Area Grade level: Fourth grade
Duration: 26 minutes  Date: 19-11-2016
Materials required: pencil, graph paper, ruler
Concepts Taught: Areas with specific units

Objectives:

At the end of the lesson students should be able to:

 Pave a domain (given a pave as a unit of measure).


 Express the area of a surface in an ordinary unit.
 Draw a Square and a Rectangle with a given area.

Introduction: (4min)

The teacher starts the lesson by telling the student a story.

The story is:

A farmer has two fields. He wants to know which of the two fields he can
harvest more wheat, the farmer needs your help to know which of the two
fields he will crop more? Why?

Activities: 

Activity 1: (7 min)
Objective: Pave a domain.
Materials: Papers, Small shapes cards to use it like a unit.
Procedures:
 Give the instructions before start.
o Give each group the same shape but with different units to measure
its area:
 Group 1: shape with squares to use it as a unit.
 Group 2: shape with rectangle to use it as a unit
 Group 3: shape with triangle as a unit.
o They will conclude that the filling is the area. Using the inductive
method they will move from the specific point pave a domain to the
general point to count the unit in order to find the area.

o They will conclude that when we want to measure an area for a


shape we will use specific unit.

Activity2: 6 min

Objectives: Express the area of a surface in an ordinary unit.


Materials: Papers with some surfaces distributed from the teacher to the
students.
Procedures:
 Give the instructions before start.
 Give students grid paper with a surface.
 Ask them to find the area of the surfaces by using the square (the
square that represent 1 unit).

Activity 3: 6min

Objective: draw square and rectangle with respect to a given area.


Materials: pencil, ruler, and graph paper.
Procedure: give students graph paper and ask them to draw a square or a
rectangle with respect to the given area.

Closure: 3min

 Summarize what we did today in our session.


 Solve the assessment sheet to check if students get the idea of the
lesson.
