Final answer:
Each friend receives 4 crayons to share the 12 crayons equally, splitting one dozen into three equal groups.
Step-by-step explanation:
The student is asking a question about division and equality, which is a mathematics problem. To share 12 crayons equally among 3 friends, each friend must receive the same number of crayons. Since 12 divided by 3 is 4, the model that correctly represents this situation would show each friend with 4 crayons.
To visualize this, you could imagine breaking the group of 12 crayons into 3 equal groups. Since a 'dozen' refers to a group of 12 objects, we're essentially splitting one dozen into three equal parts. In a classroom setting, this concept can be demonstrated with a simple hands-on activity like grouping physical crayons or drawing a diagram on the board.
