Leading Math SuccessA focus on deep learning of particular
mathematics topics – through a variety of strategies, including working with concrete materials – leads to greater conceptual depth. (Ben-Chaim, Fey, Fitzgerald, Benedetto, & Miller, 1998; Fletcher, Hope & Wagner, 2001; Siemon et al., 2001

Developing Understanding
• Each person wants to eat one half of his pizza. How many pieces must each person eat? Record your answer in fractional form.

Dispelling Misunderstanding
• When adding fractions, Joey adds the numerators and the denominators as follows:
1
4
1
3
2
7
• How can you use fraction circles to dispel this misunderstanding?

Reflection
• Timed Retell
• How can you use fraction circles to show the relationship among fractions, decimals, and percentages?
• Person A: Answer the question.• Person B: Retell what you just heard.

Leading Math Success
“The key to the successful use of manipulatives lies in the bridge - which must be built by the teacher - between the
artifact and the underlying mathematical concepts.”
