Chapter 1: Numbers and Operations
What you need to learn in this chapter
In this chapter, we will be learning about numbers and operations. We will start by understanding number value, which means we will learn how to read and write numbers up to 1,000,000. We will also learn how to determine the value of a number.
Next, we will explore prime numbers. We will learn how to identify prime numbers within 100. Prime numbers are special numbers that have only two factors, 1 and itself.
We will also study estimation. This means we will learn how to make a good guess about a quantity based on given references. We will also practice completing patterns of even and odd numbers.
Lastly, we will learn about rounding. Rounding means making a number simpler but still close in value. We will learn how to round off numbers up to the nearest hundred thousand. We will also learn how to identify numbers that can represent a rounded-off number.
By the end of this chapter, we will have a better understanding of numbers and operations, including number value, prime numbers, estimation, and rounding.
