I’m glad you addressed the faults with the pizza representation. When I previously taught multiplying fractions we had a difficult time because the students kept drawing circles instead of using the more rectangular representation.
Another piece is the language and vocabulary. Too often we let students get away with just saying a number and not putting the units with it. This is very important in fractions and in showing understanding in fractions. Another time when we need to slow down and be very deliberate with what we are modeling for our students.
