Lesson Planning of Basic Operation and Decimals (Multiplication)
Subject Mathematics
Grade 4^{th}
Students` Learning Outcomes
 The students will be able to multiply a decimal by 10, 100, and 1000.
Information for Teachers
 When multiplying by 10, 100, and 1000, etc. count the zeros to find out how much bigger your number must be.
 This is a multiplication skill and hence need drill. The more they exercise the more they understand.
 Since they have already done in tables like 2 times 10, 6 times 10 etc.
 Teacher should use/ consult from textbook where and when required.
Material / Resources
Writing board, chalk/marker, duster, paper and pencils for the whole class
Introduction
 Verbal math`s can you tell?
 2 x 10?
 4 x 100?
 10 x 10?
 What are we doing?
 What are appending zeros, as per 10 or its power?
 Today we will observe multiplication of decimal values by 10, 100, and 1000.
 Do you know?
 There is a decimal point in every number!!!
 5 is actually 5.0000…, 84 is actually 84.0000
 Just like every number these can also be written as a fraction 84 /1, 5/1 etc.
 So when we multiply these decimal jumps to right!
 Let`s see how!

Sum up / Conclusion
 When multiplying by 10, 100, and 1000 etc. count the zeros to find out how much bigger your number must be.
 In this method the decimal point moves rather that the digit.
