Mathematics Grade 4
Hi I am Tanzeela Umer, (Tanzeela.umer.gr4@auksun.com ). I am your Grade 4 teacher for Mathematics.
Mathematics is one of my favourite subjects. Because it teaches us to count the things around us.
Mathematics is spread over all the grades in our school. Like Addition and Subtraction in Grade 2, Multiplication and Division in Grade 3 etc. It advances in each grade.
In this grade, we will learn about Fractions.
A fraction represents a part of a whole thing. When something is broken up into a number of parts, the fraction shows how many of those parts you have.
So let’s get started. I’m sure you’ll love it.
This course is currently set as FREE. So go ahead, make AukSunLMS, Your Homeschool!
However, if you wish to contribute to teaching children, you may send any money.
