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.
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
This lesson promotes problem solving and reasoning with fractions as students investigate the relationships between various parts and wholes. It also focuses on representation because students are given multiple opportunities to investigate the relative value of fractions. Students use communication skills as they work in pairs to articulate and clarify their understanding of fraction relationships.
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 builds on the previous two lessons by focusing on the identification of fractional parts of a region and by recording them in standard form. Students continue to develop communication skills by working together to express their understanding of fraction relationships and to record fractions in written form.
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
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
Students use dynamic software to examine the properties of rectangles
and parallelograms, and identify what distinguishes a rectangle from a
more general parallelogram. Using spatial relationships, they will
examine the properties of two-and three-dimensional shapes. This
Internet Mathematics Excursion is based on an E-example from the NCTM
Principles and Standards for School Mathematics.
3-5
This lesson builds on the experiences of the previous lesson. Students
collect data about favorite vegetables and record the data in a
pictograph and interpret this representation. They also create and use
legends for the pictograph.
3-5
Students collect data about classmates' healthy food knowledge. They create bar graphs, pose and answer questions about the data by looking at the graphs, and find the range and mode.
