3-5
Students make and use a set of fraction strips to represent the length model, discover fraction relationships, and work with equivalent fractions.
3-5
Students create bar graphs and find the range and mode of a set of data. They explore the relationship of vowels to consonants in their names.
3-5
In this lesson, students conduct a survey and create bar graphs from the data they have collected.
9-12
In the first lesson, students make a conjecture about how the intensity of light changes as a function of the depth of the ocean. A video clip is used to prompt thinking, and students propose a graph that represents light intensity vs. depth.
9-12
In this lesson, students examine the problem of space pollution caused by human-made debris in orbit to develop an understanding of functions and modeling. It allows the students an opportunity to use spreadsheets, graphing calculators, and computer graphing utilities.
3-5
This lesson focuses on the relationship between parts and the whole.
These relationships were developed earlier and require the students to
consider the size or value of the same fraction when different "wholes"
are compared (i.e., the value of
x is relative to the whole;
x of a small pie is not equivalent to
x
of a large pie). This lesson promotes problem solving and reasoning as
the students compare similar fractions with different "wholes."
Students develop communication skills as they work in pairs and share
their understanding about the relationship between the value of a
fraction and the whole.
3-5
In this lesson, the students expand the number of fractions they can represent with pattern blocks by increasing the whole. Instead of representing the whole with one yellow hexagon, the students explore fractional relationships when two, three, and four yellow hexagons constitute the whole.
3-5
Students use virtual pattern blocks to problem solve and reason with fractions. They investigate relationships between parts and wholes using another representation of a region model, virtual fractions. Students use conversation to explain their understandings in order to extend and clarify their mathematical content knowledge.
3-5
This lesson gives students another opportunity to explore fractions using the set model. This lesson is integrated with other areas of the math curriculum including data analysis and statistics.
3-5
During this lesson, students create their own classroom survey or use previously generated questions to study the class and describe the set [class] in fractional parts. This lesson requires that students identify fractions in real-world contexts from a set of items that are not identical. This lesson is integrated with other areas of the math curriculum, including data analysis and statistics.
