Activities

[Contributor - Kripa S]

1. Make a team of 2-3 students. On student draws an angle and other student has to measure, third student will confirm if the measurement is correct. Repeat this step 4-5 times. This way the students can learn how to use a protractor

2. Make 8-10 chits of different types of angles. Hand over one chit to one bench and ask them to enact what angle they are. Eg: If it is an acute angle, the students will stand with hands close to each other. If is a complementary angle, two students will stand making an angle with their hands so that total looks 90 deg.
