# XtraMath Glossary & Icon Guide

## 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.

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.

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.

Completed a session today and answered at least 90% correct.

Completed a session today with between 10% and 25% of questions incorrect, or answered too few questions.

Completed a session today with over 25% of questions incorrect, or answered very few questions.

Signed in, but has not completed a full XtraMath 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.

The student has completed their program! If you want them to keep using XtraMath, you’ll need to assign them a new program.

💡 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.

### Operation Icons

On the class report and some other screens, the assigned operation is indicated with an icon.

The inset number on the right indicates the fluency threshold for this assigned operation.

The shade of the operation icon indicates the problem set:

Beginning operation (white fill)

Regular operation (gray fill)

Expanded operation (black fill)

## 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
