6th Math- Chapter 1 Positive Numbers and the Number Line

Lesson 1.1:  The Number Line                        Page 5

 1.  Number Line ●A horizontal or vertical line representing whole numbers, fractions, and decimals. 2.  Whole number ●Any of the numbers 0, 1, 2, 3, 4 and so on. 3.  Positive number ●A number that is greater than 0. 4.  Inequality ●A number sentence which states that two values are unequal. Example: 6>3, 8<  x Lesson 1.2:  Prime Factorization Page 16 5. Composite number ●A counting number that has more than two factors. 6. Factor (of a number) ● A whole number that divides evenly into a whole number.   Example: The factors of 10 are 1, 2, 5, and 10. 7. Prime number ●A counting number that has exactly two different factors, 1 and itself.   Example: 5 is a prime number, because its only factors are 1 and 5. 8. Prime factor ●A factor of a number that is also a prime number. Lesson 1.3 Common Factors and Multiples Page 19 9. Common factor ●A number that is a factor of two or more whole numbers 10. Greatest Common Factor ● The common factor of two or more numbers that has the greatest value 11. Common multiple ●A number that is a multiple of two or more whole numbers 12. Multiple ●The product of a whole number and any whole number. Example: 16 is a multiple of 4 13. Least common multiple ●The common multiple of two or more numbers that has the least value Lesson 1.4 Squares and Square Roots Page 29 14. Square (of a number) ●The value of a number raised to an exponent of 2 15. Exponent ●The number to which the base is raised 16. Base (of an exponent) ● tells what number is being multiplied 17. Perfect square ● The square of a whole number 18. Square root ●A number which, when squared, is equal to a given number Lesson 1.5 Cubes and Cube Roots Page 33 19. Cube (of a number) ●The value of the number raised to an exponent of 3 20. Perfect cube The cube of a whole number 21. Cube root A number which, when cubed, is equal to a given number 22. Numerical expression A collection of numbers and operations symbols that represent a single value

Chapter 1 focuses on number lines, prime factorization, finding squares and square roots, and finding cubes and cube roots.  Finding the least common multiple and greatest common factor using prime factorization are skills learned throughout this chapter as well.
