Warm Up

These warm up activities involve a general “Which One Doesn’t Belong”, visual warm ups as well as vocabulary review and may be spread out over several days or conducted in a rotation-type workshop setup.

Warm Up #1

Consider utilizing the following image with the prompt:

Which one doesn’t belong?

If you have not used a Which One Doesn’t Belong prompt before, note that the options in the image are crafted in such a way where one might be able to argue one or more reasons why any of the options do not belong based on different attributes, properties, characteristics, etc.

Some possible observations students might share include:

A doesn’t belong because: 

• it is the only shape that is not rotated around the origin
• the polygons are a different color

B doesn’t belong because 

• it is the only shape that is rotated counterclockwise
• it is the only shape that is rotated 90 degrees counterclockwise
• it is the only shape that is rotated 270 degrees clockwise 

C doesn’t belong because 

• it is the only shape that doesn’t have an area of 6 square units

D doesn’t belong because 

• it is a different shape than the others

Of course, these are just some possible observations and many more ideas may be highlighted by your students.

What do you notice? What do you wonder?

Consider utilizing the next 3 prompts as a way to remind students of some of the ideas that may have arisen during the consolidation of day 1. The prompts consist of a trapeze artist moving in different ways.  As students notice and wonder after each animation, consider emphasizing the following points if students bring them up, or perhaps suggest them yourself if they don’t.

Warm Up #2

What do you notice? What do you wonder?

• When a figure is translated on a plane, segments connecting corresponding points from the preimage to the image will be parallel and congruent

Warm Up #3

What do you notice? What do you wonder?

• When a figure is reflected across a line, segments connecting corresponding points from the preimage to the image are parallel to each other and perpendicular to the line of reflection 
• When a figure is reflected across a line, corresponding points on the image and preimage are equidistant from the line of reflection

Warm Up #4

What do you notice? What do you wonder?

• When a figure is rotated on a plane, segments connecting corresponding points from the preimage to the image via the point of rotation will have the same angle measures

Warm Up #5 [Word Bank]

There are a variety of ways to use the word bank in a warm up. One simple way is to have students stand with a partner. Partner 1 is facing the projector screen and can see the words,  while Partner 2 stands facing Partner 1 . Partner 1 must provide clues to the vocabulary words, without using the words themselves. 

Another way is to have students create sentences using the words, in a game similar to “two truths and a lie”.  Each group must create 3 sentences using two words each. Two sentences must be TRUE, one must be FALSE or represent a common misconception.  Other groups must point out the false statements.

In part 2, Partner 1 and Partner 2 might switch places.
