State Data

3-5

Students create graphs based on the characteristics of the names of the 50 States, and find mean, median, mode, and range of the data.

Making and Investigating Fraction Strips

3-5

Students make and use a set of fraction strips to represent the length model, discover fraction relationships, and work with equivalent fractions.

Students continue to work with fraction strips to compare and order fractions. This lesson builds on the work done with fraction relationships in the previous lesson. Students develop skills in problem solving and reasoning as they make connections between various fractions.

Investigating Fraction Relationships with Relationship Rods

3-5

Students use relationship rods to explore fraction relationships. This work with relationships lays the foundation for work with more challenging fraction concepts.

Relationship rods are wooden or plastic rods in ten different colors. They range in length from one to ten centimeters. Each length is a different color.

Investigating Equivalent Fractions with Relationship Rods

3-5

Students investigate the length model by working with relationship rods to find equivalent fractions. Students develop skills in reasoning and problem solving as they explain how two fractions are equivalent (the same length).

Inch by Inch

3-5

In this lesson, students use a ruler to represent various fractions as lengths. This lesson builds on the work done in the previous lessons with as students use a standard instrument to measure a variety of items, including items which can be measured to the nearest half and quarter of an inch.
