Which of the following statements is true when introducing fraction computation? (Mark all that apply.)
a. introduce fraction computation using only one model, i.e., fraction circles or other parts-of-the-whole model, to avoid confusing students
b. limit students' use of manipulative models to avoid overdependence on manipulatives
c. introduce the fraction algorithms along with allowing students to use manipulatives
d. give students different kinds of fraction models, i.e., fraction circles, fraction number lines, and sets of objects, as they explore fraction computation
d
