Patterning in Math Today

Today in math we reviewed what an 'attribute' is. An attribute is the part of the pattern that is changing. Some of the attributes that we have been noticing in our patterns are:
-colour
-size
-shape
-thickness
-direction

Today students created their own patterns and their math partners tried to determine which attributes were changing in the pattern.
Grade Two students are learning to create patterns with one attribute changing.
Grade Three students are learning to create patterns with two attributes changing.

Below are some photos of patterns that students created today. Can you figure out which attributes are changing?
