WHOLE NUMBERS: For the first area under addition, we will cover whole numbers. We will understand about addends and sums. We will understand the relationship between addition and subtraction problems. A whole number is all the natural numbers (or counting numbers) and zero; not any negative numbers. The numbers that we are adding are called addends; the answer to an addition problem is called the sum. We will learn how to convert a whole number to a fraction. DECIMALS: We will learn how to determine the whole number and decimal parts. We will learn to convert decimals to fractions. We will learn the importance of lining up the decimals. Decimals are one way of describing a part that is less than a whole number. Mixed numbers have a decimal separating the whole number part and the decimal part. FRACTIONS: We will be able to distinguish a proper fraction, an improper fraction, and a complex fraction. A proper fraction's numerator has a smaller number than its denominator. An improper fraction's numerator has a larger number than its denominator, A complex fraction is a fraction over a fraction, a mixed number over a mixed number, or any combination of these. We will learn about numerators and denominators; we will learn to find common denominators. A numerator is the number above the line in a fraction. A denominator is the number below the line in a fraction. After awhile, we will understand that all fractions are division problems. A denominator will be also known as a divisor; a numerator will be known as a dividend within a division problem. .
