Introduction
Depending on the variables, terms may be classified as like & unlike terms
Pre-Requisites:
Terms, coefficients, factors, variables of an algebraic expression
Activity:
It’s all about similarity. Anything that falls into one category will be represented by a single variable. Then they are like terms. Isn’t that how it is, in general? You can become better friends with people who have same interests & hobbies as you ?
Real Life Question:
None as such. In any case, same as that of Algebraic expressions intro. But like and unlike terms are identified so as to group them in order to solve them easily
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Like Terms | Terms having same variable type , Ex: 13x, & -4x, 4xy & -2xy |
| Unlike Terms | Terms having different variables, Ex: 6x & 8xy, 3x & 4x2 |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Horse gram | If you are buying horse gram in different places (like Hyderabad & Bangalore) cost at each place varies. Comparing those two expressions, you will see they are like terms |
Real life uses :
When you want to make measurements, you would separate objects having same shapes & different shapes in order for it to become easy.
Places to visit :
Super market
Practical examples around us
| Examples | Explainations |
|---|---|
| Marbles | Considering marbles as variables-Two green marbles would be “like terms” whereas a green and a yellow marble put together may be called “unlike terms” |
What you learn in Theory:
About like and unlike terms
What you learn in Practice:
Grouping similar terms and putting them under one heading would make it easier for analysis
