LINES AND ANGLES

 

ACTIVITY –2. The angle grid

DATE:

 

AIM / Objective:

To identify the angles and their properties

 

MATERIALS REQUIRED:

Pencil, scale, eraser

 

PREREQUISITE KNOWLEDGE:

Concept of angles and their properties

 

PROCEDURE:

Description:

1. The students will be given a grid with 9 pairs of angles with their properties, written randomly.

2. The students will cut out the given grid into 18 triangular pieces and arrange them pair wise to form 9 squares i.e. each paper of angles with its identification

criteria.

3. Now the students will arrange the 9 squares to form a (3 x 3) grid.

 

LEARNING ASSESSMENT:

Arrange the squares to form a grid

PREREQUISITE KNOWLEDGE:

Concept of simple equations

 

PROCEDURE:

Description:

Note down postal pin code of your place where you reside. Take x times of last 2 digits of that pin code and add number of family members to it. Put it equal to your age

 

LEARNING ASSESSMENT:

 

solve for x on A4 coloured sheet.

 

 

Postal pin code	631001	631001
x times of last 2 digits	01	01*x
add number of family members	7	X+7
Put it equal to your age	13	X+7=13
Equation
Solve for x		X=6
