Algebra language crossword vocabulary pack

Teacher key

1. CONSTANT · 8 letters · noun · introductory
   Fixed number in an expression

   Hint: It keeps the same value even when letters change.
   Why it fits: CONSTANT fits because algebra uses it for a fixed value, such as 7 in 3x + 7, that remains the same while variables may vary.

2. EXPRESSION · 10 letters · noun · introductory
   Algebraic phrase without an equals sign

   Hint: It can contain numbers, letters, and operation symbols.
   Why it fits: EXPRESSION is correct because 4n - 2 names a value rule, while an equation would assert that two quantities are equal.

3. TERM · 4 letters · noun · introductory
   Single addend inside an algebraic phrase

   Hint: In 5x + 9, there are two of these pieces.
   Why it fits: TERM fits because algebra groups expressions into addends such as 5x and 9, each carrying its own coefficient or value.

4. FACTOR · 6 letters · noun · introductory
   Number or expression multiplied with another

   Hint: Breaking 12x into 3 and 4x shows two examples.
   Why it fits: FACTOR is correct because products can be decomposed into multiplied parts, a key idea in simplifying and solving algebra problems.

5. SLOPE · 5 letters · noun · intermediate
   Measure of steepness on a graph

   Hint: It compares vertical change with horizontal change.
   Why it fits: SLOPE fits because linear relationships use this value to show rate of change and direction across the coordinate plane.

6. INTERCEPT · 9 letters · noun · intermediate
   Graph point where a line crosses an axis

   Hint: One type occurs where x equals zero.
   Why it fits: INTERCEPT is correct because graphing equations often starts by finding where the line touches either coordinate axis.

7. QUADRATIC · 9 letters · adjective · advanced
   Describing an equation with a squared variable as its highest power

   Hint: Its graph commonly has a U-shaped curve.
   Why it fits: QUADRATIC fits because equations like y = x^2 + 3x - 4 have second-degree behavior and graph as parabolas.

8. LINEAR · 6 letters · adjective · introductory
   Describing a relationship that graphs as a straight line

   Hint: A steady rate of change is the giveaway.
   Why it fits: LINEAR is correct because first-degree algebraic relationships create straight graphs and predictable additive patterns.

9. POLYNOMIAL · 10 letters · noun · advanced
   Expression made from added powers of variables

   Hint: Examples can have one, two, or many named parts.
   Why it fits: POLYNOMIAL fits because algebra class groups monomials, binomials, and trinomials under this broader expression type.

10. MONOMIAL · 8 letters · noun · intermediate
    Polynomial with exactly one part

    Hint: 6x^3 is a typical example.
    Why it fits: MONOMIAL is correct because it names expressions such as 8 or 2ab that are not split by plus or minus signs.

11. BINOMIAL · 8 letters · noun · intermediate
    Polynomial with exactly two parts

    Hint: x + 5 is a short example.
    Why it fits: BINOMIAL fits because algebra uses the word for expressions like a - b and x^2 + 3 that contain exactly two terms.

12. TRINOMIAL · 9 letters · noun · intermediate
    Polynomial with exactly three parts

    Hint: x^2 + x + 1 has this structure.
    Why it fits: TRINOMIAL is correct because many factoring lessons begin with expressions of the form ax^2 + bx + c.

13. RADICAL · 7 letters · noun · advanced
    Symbol or expression involving a root

    Hint: The square-root sign is the most common example.
    Why it fits: RADICAL fits because algebra uses it when rewriting or solving expressions that contain square roots or other roots.

14. ABSOLUTEVALUE · 13 letters · noun · intermediate
    Distance from zero on a number line

    Hint: The result cannot be negative in basic algebra work.
    Why it fits: ABSOLUTEVALUE is correct because both -6 and 6 are six units from zero, so the notation returns the same magnitude.

15. LOGARITHM · 9 letters · noun · advanced
    Exponent needed to produce a given number

    Hint: It answers the question, what power is required?
    Why it fits: LOGARITHM fits because log base 10 of 100 equals 2, since 10 raised to the second power gives 100.

16. ASYMPTOTE · 9 letters · noun · advanced
    Line a graph approaches but may not reach

    Hint: Rational and exponential graphs often have one.
    Why it fits: ASYMPTOTE is correct because it describes a boundary line that shapes how certain functions behave far from the origin.

17. PARABOLA · 8 letters · noun · intermediate
    U-shaped graph of a second-degree relation

    Hint: Projectile paths are often modeled with this curve.
    Why it fits: PARABOLA fits because equations with squared variables often open upward or downward in this curved, symmetric form.

18. MATRIX · 6 letters · noun · advanced
    Rectangular array of numbers used in algebra

    Hint: Rows and columns organize its entries.
    Why it fits: MATRIX is correct because advanced algebra uses such arrays for systems of equations, transformations, and organized calculations.

19. SEQUENCE · 8 letters · noun · intermediate
    Ordered list following a rule

    Hint: Arithmetic and geometric patterns are common types.
    Why it fits: SEQUENCE fits because algebra studies lists like 3, 6, 9, 12 or 2, 4, 8, 16 to describe patterns.

20. DOMAIN · 6 letters · noun · advanced
    Set of input values allowed for a relation

    Hint: Restrictions may come from division by zero or square roots.
    Why it fits: DOMAIN is correct because functions are interpreted by first deciding which x-values are permitted in the situation.
