The Shape of Things

We have been learning about 2 dimensional shapes and their attributes.

The Circle Map is used to brainstorm ideas and show what you already know about a topic by using context information. This can be words, numbers, pictures, symbols, etc. to represent the object, person, or ideas you are trying to understand or define.

Written in the inner circle is some "thing" you are trying to define. It is represented by a word or symbol. In the outer circle, information is written or drawn that puts the "thing" in context. The square around the circles is called the frame of reference. This is where "how you know what you know" is added.

we made circle maps showing what we know about shapes

In the lab, we used Pixie to make a circle map showing where you can find shapes in the real world.

The Bridge Map is used to identify similarities between relationships (seeing analogies). Students use a relating factor which is a similar phrase which fits both sides of the analogy.
The relating factor in our bridge map is where basic shapes are found in the world around us.

We are learning to write to inform and we are learning about the attributes of shapes, so students chose a shape, drew it, and wrote 2 sentences telling about it.
