The purpose of this task is for students to translate between measurements given in a scale drawing and the corresponding measurements of the object represented by the scale drawing.

The purpose of this task is for students to solve a contextual problem where there are multiple entry points to this geometry based concept.

The goal of this task is to gather together knowledge and skills from the seventh grade in a context which prepares students for the important eighth grade notion of similarity.

The purpose of this task is to apply knowledge about triangles, circles, and squares in order to calculate and compare two different areas.

Students' first experience with transformations is likely to be with specific shapes like triangles, quadrilaterals, circles, and figures with symmetry. Exhibiting a sequence of transformations that shows that two generic line segments of the same length are congruent is a good way for students to begin thinking about transformations in greater generality.

This task gives students a chance to explore several issues relating to rigid motions of the plane and triangle congruence.

The purpose of this task is for students to use what they know about area to find the areas of special quadrilaterals.

Find the area that is shaded in each figure in at least two different ways.

The purpose of this task is for students to experiment with composition and decomposition of polygons to examine shapes in a real world context.

This is the second in a series of four tasks that gradually build in complexity. The purpose of this series of tasks is to build in a natural way from accessible, concrete problems involving volume to a more abstract understanding of volume. In this iteration, we do away with the lines that delineate individual unit cubes (which makes it more abstract) and generalize from cubes to rectangular prisms. However, the calculations are the same as in 6.G Computing Volume Progression 1.

The purpose of this task is to introduce students to fractional units for volume.

The goal of this task is to work with nets for three-dimensional shapes and use them to calculate surface area.

The goal of this task is to gather together knowledge and skills from the seventh grade in a context which prepares students for the important eighth grade notion of similarity.

The purpose of this task is to help students differentiate between a circle and the region inside of the circle so that they understand what is being measured when the circumference and area are being found.

The purpose of this task is for students to find the area and perimeter of figures composed of squares and fractions of circles.

The purpose of this task is to help students visualize one way to derive the formula for the area of a circle, which uses the formulas for the circumference of a circle and the area of a parallelogram

The purpose of this task is for students to find a way to decompose a regular hexagon into congruent figures.

The purpose of this activity is to help students think a little more flexibly about the concept of area before studying, generally, the areas of triangles and special quadrilaterals.

This is the first in a series of four tasks that gradually build in complexity. The purpose of this series of tasks is to build in a natural way from accessible, concrete problems involving volume to a more abstract understanding of volume. The purpose of this first task is to see the relationship between the side-lengths of a cube and its volume.

Use the idea of scaling to show that the ratio Area of Circle: (Radius of Circle)2 does not depend on the radius.
Use formulas for the area of squares and triangles to estimate the value of the real number c satisfying
Area(Circle of Radius r)=cr2.
