Lesson Plan
[Author - Kripa S]
Objective: Explain properties of squares and square roots
Subtopics to be covered:
- Squares from 1 - 20, square roots for numbers till 100
- Properties of squares- digits ending with 1,4,5,6,9,0
- Non perfect square numbers between two squares
- Square root by factorization method
- Square root by division method
Learning Outcome:
- Students can give the squares of any number
- Students can find the square root of any number by one of the two methods
- They know the properties to identify squares for a number
