3, 9/3 2 4 6/3 12/3
Observe student boards. Check to see if they partitioned it into 3rds and placed 2 at the start, 3 in the middle and 4 at the end with their fraction form above them.
300
Libby is arguing with Ashley. Libby has 2 chocolate bars and said she would give Ashley half of each bar. Ashley thinks this isn't fair! How can you explain to Ashley that this is fair and they will each get the same amount?
Take acceptable responses. Look for them to use a model to explain their thinking.
1/2 + 1/2 is one whole bar. They would each still get 1 bar.
