Hexagons in a Row - Inside Mathematics

Student F is able to complete a table by adding 5’s to solve much of the task. However in part four,
the student tries to use proportional reasoning if 4 hexagons are 21, then 21 x 3 should equal 12
hexagons. This reasoning does not work, because the constant is now included in the total 3 times
instead of just once.
