## 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.

- 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.

### Addition

**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

### 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**Multiply:**repeated addition**Product:**the answer in a multiplication equation

### Division

**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)**Quotient:**the answer to a division equation
