XtraMath Terms

  • Fluency: a student’s progress toward completing an operation in Xtramath.
  • Fluency Threshold: the amount of time students have to answer a problem.
  • Timeout: refers to the total amount of time the student has to enter the answer to a problem. Upon timeout, the answer is shown with an hourglass icon. The student must enter the answer to continue on to the next problem. The default six-second programs have a timeout of 20 seconds.
  • Operation: a mathematical process such as addition, subtraction, multiplication, or division.
  • Beginning: a program containing a limited set of facts. Beginning Addition has only problems that add up to 10 or less, such as 3 + 7. Beginning Subtraction has their inverses, such as 10 − 3.
  • Regular: a program containing all single digit facts. For example, Regular Addition facts go up to 9 + 9, and Regular Division facts go to 81 ÷ 9. If “Beginning” or “Expanded” is not specified, a program contains Regular facts.
  • Expanded: a program containing a larger set of facts. All expanded operations have facts up to 12s, such as 12 + 7 or 132 ÷ 11.

XtraMath Icons

Answer icons

These icons show how a student answered a specific question in a quiz or practice activity. They are used as feedback in the student activities, and also appear on the date report.

  • Smiley face iconAnswered correctly within the fluency threshold. This depends on the program but is 6 seconds by default.
  • Green checkmark iconAnswered correctly, but beyond the fluency threshold.
  • Red X iconAnswered incorrectly.
  • Hourglass iconNo response given before time ran out and the correct answer was shown.
  • Moon icon with ZsIdle time after the correct answer was shown.

Daily usage icons

These icons are a quick indicator of how well a student did on that day. They are used on all of the reports.

  • Green circle iconAnswered at least 90% correct.
  • Yellow square iconBetween 10% and 25% of questions incorrect, or answered too few questions.
  • Red octagon iconOver 25% of questions incorrect, or answered very few questions.
  • Incomplete iconSigned in, but has not completed a full XtraMath session.

Student status icons

These icons show a student’s current XtraMath status for today. They appear on the Student and Classroom Sign In pages, and on the online class report.

  • Status icons: green, yellow, and red shapes with checkmarks, and a gray shape with an arrow

    These status icons correspond with the usage icons above. A checkmark indicates the student has completed a session today. If a student’s current status is incomplete, it’s possible that they are working on XtraMath right now and just have not finished their session yet.

    On a Sign In page, all checkmark icons displayed are green, for student privacy. In the online class report, the color and shape of the icon reflects the student’s performance.

  • Gold star iconThe student has completed their program! If you want them to keep using XtraMath, you’ll need to assign them a new program.
  • Orange busy iconMarked “busy” on the Classroom Sign In page.
  • Red absent iconMarked “absent” on the Classroom Sign In page.

Math Vocabulary

  • Equal sign (=): the symbol that shows what is on the left of the sign is exactly the same amount as what is on the right of the sign. For example, 2 + 5 = 7 means that 2 + 5 is equal to 7.


  • Add: to bring two or more numbers or things together to make a whole
  • Addend: the number added to another number
  • Commutative Property: the numbers can be moved or swapped from their position without making any difference to the answer
  • Increase: to make something bigger
  • Plus (+): the symbol used for an addition problem
  • Sum: the answer to an addition problem


  • Inverse Operations: operations that can undo each other (Addition and Subtraction)
  • Subtract: taking one number away from another
  • Subtrahend: the number to be subtracted from another number
  • Minus (-): the symbol used for a subtraction problem
  • Difference: the result of subtracting one number from another
  • Decrease: to make something smaller


  • Commutative Property: the numbers can be moved or swapped from their position without making any difference to the answer
  • Factors: the numbers that are multiplied together
  • Multiplicand: the number to be multiplied
  • Multiplication sign (×): the symbol used for a multiplication problem
  • Multiplier: is the number that tells how many times a multiplicand should be multiplied
  • Multiply: repeated addition
  • Product: the answer in a multiplication equation


  • Divide: repeated subtraction
  • Dividend: the number being divided
  • Division Sign (÷): is placed between the dividend and the divisor
  • Divisor: is the number that tells how many times a dividend should be divided
  • Equal Groups: groups that have the same number of objects
  • Inverse Operations: operations that can undo each other (Multiplication and Division)
