Activity Description The same as "Bounded Fraction Pointer" but there is no arrow to help the user determine the value of the fractions between the two endpoints. Bounded Fraction Finder is one of the Interactivate assessment explorers.

Bounded Fraction Finder

Place in mathematics curriculum:

• Practice simplifying fractions
• Compare fractions and order them on a number line
• Develop algorithms to estimate fractions

This activity allows the user to visually experiment with the relationship between the value of fractions and areas within a square or a circle. This activity would work well in groups of two to four for about 30 minutes if you use the exploration questions and 15 minutes otherwise.

Preparations for this activity:

• give implicit directions on what they are to do. For example "Today we are going to compare fractions and use the number line."
• discuss different methods to mentally approximate fractions.
