This task provides an opportunity to examine the taxonomy of quadrilaterals from the point of view of rigid motions.
This task examines quadrilaterals from the point of view of rigid motions and complements.
This task examines the rigid motions which map a rectangle onto itself.
Open Middle provides math problems that have a closed beginning, a closed end, and an open middle. This means that there are multiple ways to approach and ultimately solve the problems. Open middle problems generally require a higher Depth of Knowledge than most problems that assess procedural and conceptual understanding.

This simple conceptual problem does not require algebraic manipulation, but requires students to articulate the reasoning behind each statement.
In this task students are given graphs of quantities related to weather. The purpose of the task is to show that graphs are more than a collection of coordinate points, that they can tell a story about the variables that are involved and together they can paint a very complete picture of a situation, in this case the weather.
This task gives an easy context to introduce the idea of average rate of change. This problem could be done as a Think-Pair-Share activity. After posing the question, students can decide what they think and why and then discuss their answer with their neighbor.
The purpose of this task is to assess ability to interpret the slope and intercept of the line of best fit in context.
This Illustrative Mathematics task requires students to identify expressions as sums or products and interpret each summand or factor.
The task illustrates A-SSE.1a because it requires students to identify expressions as sums or products and interpret each summand or factor.
Last Sunday an accident caused a traffic jam 12 miles long on a straight stretch of a two lane freeway. How many vehicles do you think were in the traffic jam? Explain your thinking and show all calculations.

The purpose of this task is to apply the Pythagorean theorem to calculate distances and areas.
The goal of this task is to use ideas about linear functions in order to determine when certain angles are right angles.
