What is a translation?
100
This model uses rectangles to visualize multiplication problems.
What is the area model?
200
This multiplication context can be thought of as 'groups of' objects.
What is repeated addition?
200
This term describes a comparison between two quantities using division
What is a ratio?
200
The equal sign in an equation can be thought of as this object on a balance scale.
What is a fulcrum?
200
This transformation creates a mirror image of a figure across a line.
What is a reflection?
200
This visual model helps students understand positive and negative integers
What is a number line?
300
In division, this term refers to the number being divided
What is the dividend?
300
This special type of ratio involves a unit of measurement, like miles per hour.
What is a rate?
300
In a linear relationship, this value represents the constant rate of change.
What is the slope?
300
This term describes when shapes have the same size and shape
What is congruence?
300
This model shows how equations can be balanced, with equal quantities on each side.
What is a balance scale model?
400
This property applies to addition and multiplication but not to subtraction or division
What is the commutative property?
400
When a percent is greater than 100%, it represents this type of change from the original amount.
What is an increase (or growth)?
400
When solving inequalities, we must do this when multiplying or dividing by a negative number
What is flip (or reverse) the inequality sign?
400
This transformation turns a figure around a fixed point by a certain angle.
What is a rotation?
400

What is a four-step approach to tackling mathematical and real-world problems?
500
Repeated multiplication of the same number (e.g., 2^3 = 2 * 2 * 2)
What is exponentiation?
500
These two ways of comparing amounts represent different mathematical relationships.
What are additive and multiplicative comparisons?
500
This type of sequence multiplies by the same factor each time, creating exponential growth
What is a geometric sequence?
500
This complex transformation combines a reflection and a translation parallel to the line of reflection
What is a glide reflection?
500
These three tools can help model and make sense of real-life problems in algebra.
