Activity that can be used either as an introduction to the unit or can be used later in the unit to informally assess student thinking.

These three parts are intended to support students in making connections between 2 dimensional and 3 dimensional objects, especially how scaling changes these objects and how we can carefully partition objects in order to make relationships between two otherwise different geometric shapes.

Task that requires students to apply surface area and density to a real world situation.

Task that requires students to create a mathematical based plan to find the thickness of a soda can.

This lesson is intended to help assess how well students are able to interpret and use scale drawings to plan a garden layout. This involves using proportional reasoning and metric units.

This FAL is intended to help you assess how well students are able to:
Recognize and use common 2D representations of 3D objects.
Identify and use the appropriate formula for finding the circumference of a circle.

This lesson is intended to help you assess whether students recognize relationships of direct proportion and how well they solve problems that involve proportional reasoning. In particular, it is intended to help you identify those students who:
* Use inappropriate additive strategies in scaling problems, which have a multiplicative structure.
* Rely on piecemeal and inefficient strategies such as doubling, halving, and decomposition and have not developed a single multiplier strategy for solving proportionality problems.
* See multiplication as making numbers bigger and division as making numbers smaller.

Students will learn about the relationship between the surfaces of a 3 dimensional shape and what that shape looks like in 3d.
