My son put thirds and his teacher marked it wrong

Question

A class of 24 students is divided into 6 equal groups. Each group has

2 sheets of poster board. Each person in the group wants an, equal part.

Should each group cut the sheets of poster board into halves of thirds?

Answer 1

24 divided into 6 equal groups means

24/6 = 4 students in each group

2 poster boards per group means 2/4 = 1/2 poster board for each student.

each group should cut the poster board into halves.

one-half for each student

24 students with 1/2 each means 12 poster boards total. each group of 6 students would get 2 poster boards. 2 x 6 = 12.

halves not thirds is the correct answer

if they cut the poster boards into thirds, every student would still get an equal share, 1/3 of a poster board, but each group would have 2/3 of a board left over.
