## 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

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.

• Answered correctly within the fluency threshold. This depends on the program but is 6 seconds by default.
• Answered correctly, but beyond the fluency threshold.
• Answered incorrectly.
• No response given before time ran out and the correct answer was shown.
• Idle 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.

• Answered at least 90% correct.
• Between 10% and 25% of questions incorrect, or answered too few questions.
• Over 25% of questions incorrect, or answered very few questions.
• Signed 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.

• 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.

• The student has completed their program! If you want them to keep using XtraMath, you’ll need to assign them a new program.
• Marked “busy” on the Classroom Sign In page.
• Marked “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
• 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

### Subtraction

• 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

### Multiplication

• 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
