a)  
b) 
Any answer (not marked). This is about how easy/difficult students found it.

c) 
Accept answer that describes working out one attribute and then the other, e.g.,

d)  The kind of shape and the number of sides are attributes that are not needed to answer sort these shapes in this resource. 
Teaching and learning:
This resource is about sorting 2dimensional shapes using two attributes.
Diagnostic and formative information:
Student response  Next steps 
Students correctly sort 59 shapes with none incorrectly sorted or
Students correctly sorting 89 shapes with 12 incorrectly sorted

Get students to do other sorting problems involving two attributes.
Encourage them to check every shape and justify to a peer.

Student exhibits multiple errors 
Get students to sort physical shapes based on one attribute (colour or number of sides) placing them over the attribute used in the labelled margin of the table (e.g., put all red shapes over to the left of the word "Red", and the same with Green and Yellow).
Next, get them to decide which cell of the "Red" row, each red shape should be placed.
Repeat for Green and Yellow.
Then within each cell ask whether the shape is small or large.
