Teaching maths adopt some mathematical techniques from "Vedic Mathematics"--it is very easy- interesting and research oriented.
Good for all ages. It also creates interest amazingly.

Mental math is one way that you can build math skills, create critical thinking, and help strengthen logical thinking skills. Math is a complex subject containing many different areas. Math can be daunting to students, and can get more difficult as time passes. Mental math activities help students realize the potential in math, connect math to their everyday lives, and practice math skills for the real world.
Begin mental math at the lower grades (kindergarten through third) and with students who are at lower levels in math by doing easy answer questions. Have the class work as a team to shout out the right answers. Present students with simple math equations and questions that fit their age level, such as "What comes after eight" for kindergarten students, and "What is one plus two" for first-graders. Have students sit in their chairs with their hands in their lap. The first student to come up with a guess should shout it out. The goal would be to reach the point where all students in the class are shouting out the answer together.
As students get older, use easy answers as a warm-up to more complex mental math activities. Students can use this for their times tables, their division facts, and even basic algebra, such as "x plus three equals nine," with students then answering what "x" is.
Much of math as it is used in everyday life is mental math. A person at a store must figure out what60 percent of $20 equals. A driver must figure out how many hours it will take him to travel230 miles for a trip. Use complex mental math questions that relate to everyday use. Each morning, write a complex mental math problem on the board. It should be age appropriate: "60 percent of $230" is appropriate for seventh-graders, while "10 percent of100" is better suited for fourth-graders. When in doubt, pull a math concept and question from that week's math lessons. As students come into the room, they should read the math problem and quietly sit at their desks to think about the answers. You can then have the students shout out answers or write down answers on paper and hand them in, depending on your teaching methods.
