  1. 1. An early counting tool used for basic arithmetic.
  2. 3. A set of numbers or objects that follow a specific pattern.
  3. 5. The average is the same as the mean. Add up a series of numbers and divide the sum by the total number of values to find the average.
  4. 8. The bottom of a shape or three-dimensional object, what an object rests on
  5. 10. The branch of mathematics that substitutes letters for numbers to solve for unknown values.
  6. 11. A grouping of terms or values that use a sign to show an equal relationship — that two quantities are equal. By using an equation, tough problems can be reduced to easier problems and simpler answers.
  7. 14. either a single number or a variable, or numbers and variables multiplied together.
  8. 16. a number used to multiply a variable (4x means 4 times x, so 4 is a coefficient)
  9. 17. A grouping of terms or values that use a sign to show an equal relationship — that two quantities are equal. By using an equation, tough problems can be reduced to easier problems and simpler answers.
  10. 18. The two-dimensional space taken up by an object or shape, given in square units.
  11. 19. A value or number that never changes in an equation — it’s constantly the same.
  12. 20. A procedure or set of steps used to solve a mathematical computation.Algorithm: A procedure or set of steps used to solve a mathematical computation.

  1. 2. A graph that represents data visually using bars of different heights or lengths.
  2. 4. A number involved in an addition problem; numbers being added are called addends.
  3. 5. Two rays sharing the same endpoint (called the angle vertex).
  4. 6. a group of terms (the terms are separated by + or − signs)
  5. 7. An action performed upon one or two numbers to produce a resulting number. Operations are addition, subtraction, multiplication, division, square root, and so on.
  6. 9. Number system that assigns place value to numbers.
  7. 10. The line dividing an angle into two equal angles.
  8. 12. A characteristic or feature of an object—such as size, shape, color, etc.—that allows it to be grouped.
  9. 13. An angle whose measure is between 0° and 90° or with less than 90° radians.
  10. 15. Always a positive number, absolute value refers to the distance of a number from 0.
