Math - Student Resources in Context
Mathematics (often abbreviated Math), in the very broadest sense, is the systematic study of relationships in the physical world and relationships between symbols that need not pertain to the real world. In relation to the world, mathematics is the language of science. It operates within the laws and constraints of science as it examines physical phenomena. Mathematicians, those who delve into and study mathematics, formulate new conjectures from the deduction of existing axioms and definitions. Unlike science, however, mathematics has no constraints. So, in relation to symbols, mathematics can be considered a pure mental activity that is capable of generating...View More

- MathematicsMathematics is the field of study that deals with the measurement, properties, and relationships of quantities, as expressed in either numbers or symbols. For example, a farmer might decide to fence in a field and plant oats there. He would have to use mathematics to measure the size of the field, to calculate the amount of fencing needed for the field, to determine how much seed he would have to buy, and to compute the cost of that seed. Mathematics is an essential part of every aspect of life--from determining the correct tip to leave for a waiter to calculating...View More..

An Introduction to Fractions Subject(s): Mathematics |
Objectives Students will be introduced to fractions, including equivalent fractions, nominators, and denominators. Preparation Copy and distribute the printable Resources section below. Have students read the essay for background information and consult any or all of the encyclopedia articles that follow it to learn more about the topic. Resources Essay: Numbers such as 1, 2, 3, 5, 10, 120, and 4,000 are called whole numbers, or integers. When you multiply one integer by another, the answer is always an integer: 5 × 6 = 30; 7 × 9 = 63. However, it is not always possible to obtain an integer as an answer when you divide one integer by another. If 8 apples are to be divided into 3 equal shares, the result is 8/3, which is a fraction. This fraction can be reduced to a whole number and a remaining fraction—that is, 8/3 equals 22/3. Therefore, if you were to divide 8 apples equally among 3 people, each person would receive 2 whole apples plus 2/3 apple. Activity Create a display showing the fractions of men and women in different occupations—for example, teachers in your school, police officers in your community, legislators in your state, senators and representatives in the U.S. Congress. For Discussion What are the numerator and denominator of a fraction? Can zero be a denominator? Why or why not? How does one add fractions when all the denominators are the same? How does one add fractions when the denominators are different? Give some examples of how fractions are used in everyday life. Extension Go further by completing one or more of the following assignments:
Assessment Use drawings of pizzas to demonstrate the fractions 1/ 3, 1/4, 3/4, and 7/8. Suggested Terms for Searching: Arithmetic Fraction Number Fractions and Decimals Numbers and Number Systems Suggested Resources: |
