## Types of Functions-

IB Maths Tutors should give twenty-two hours for teaching functions and equations as per IBO recommendations. This is my third article on functions in the series of ib mathematics

For the sake of a comprehensive discussion, some standard functions and their graphs are discussed here

For the sake of a comprehensive discussion, some standard functions and their graphs are discussed here.

**1.Greatest Integer Function**– This is an interesting function. It is defined as the largest integer less than or equal to x

* y*

**= [**

*x*].For all real numbers, *x*, this function gives the largest integer less

than or equal to *x*.

For example: ** [1] = 1 [2.5] = 2 [4.7] = 4 [5.3] = 5**

*Beware!*** [-2] = -2 [-2.6] = -3 [-4.1] = -5 [-6.5] = -7**

domain=**R**

range=**Z**

## IB Maths (Part-1)- Functions-An Introduction to functions in Mathematics

### An Introduction to functions in Mathematics

In IB Maths both HL and SL, functions are one of the most important areas of mathematics because they lie at the heart of much of mathematical analysis. The concept of function is easy to understand.

Suppose I say that:

** y=x² **

where **x∈R.** This says that y depends on** x** this can be said that **y** is a function of** x**. or

** y=f(x)**

We can also say that **x=√y** here x depends on y or x is a function in y or

** x=f(y) **

so it can be said that a function is an operator which takes an input and gives an output.The input is called independent variable while output is called dependent variable

## How to Become a Good Learner in Classroom or in Online sessions

Every moment of our life offers something to learn.We should always be ready to grab the opportunity.In this post, I have tried to identify characteristics of a good learner in classroom as well as with online tutors

**Positive Attitude-** A positive attitude plays a very important part in improving our learning capacities.Actually, its the backbone of our learning capacities.If we believe that we can do it, we will surely be able to accomplish the work Read more

## Teaching Maths-Classroom discussions

## Teaching Maths-Classroom discussions

Teaching Mathematics is an art but there are certain factors about it that we can learn and improve our academic delivery.

Creating productive classroom discussions is one of them

Lecture method may work very well for some subjects but not all the time in Mathematics classes.

Engaging students by constantly asking them some questions is a nice method but only when the explanation and the questions are Mathematical. Reasoning and justifying are good habits of mind but they are only productive if they are based on Mathematical theories.

Creating a productive classroom discussion is probably the most difficult part of Mathematics teaching. I suggest five methods for moving beyond Lecture methods in teaching Mathematics.

I have always tried to practice these methods in my own teaching whether with students or with teachers and I have found them very useful

**1. Predict the Pupils’ Responses of Mathematics**

All the teachers should know about each and every student how he/she is going to react to the instructional tasks(s) that they are asked to work on. Read more
