What is the primary reason for delaying the use of nonproportional models when introducing place-value concepts?
◦ Models do not physically represent 10 times larger than the one.
◦ Models like abacus are hard to learn how to use.
◦ Models like money provide more conceptual than procedural knowledge.
◦ Models do not engage the students as much as the proportional models.
