Chapter 1 : Numbers and Operations
What will you learn in this chapter
Next, we will explore odd numbers and even numbers. We will learn how to identify and differentiate between them.
We will also learn about estimation, which involves giving reasonable estimates for quantities based on a given reference set. We will practice justifying our answers.
Lastly, we will learn how to round off whole numbers to the nearest ten thousands. We will understand the concept of rounding off and practice applying it.
Let's get ready to explore the world of whole numbers and basic operations!
