Constructing a three-dimensional model
http://illuminations.nctm.org/LessonDetail.aspx?ID=L653
A lesson plan for grades 3 and 5 Mathematics
In this lesson, students build a three dimensional model from their two dimensional blueprint. In addition, they solve problems related to constructing and decorating their clubhouse. Illuminations provides an overhead, a problem-solving packet, and detailed instructions for completing the lesson.
Students will:
- Transform a two dimensional plan into a three dimensional figure.
- Apply problem solving strategies.
NCTM Standards and Expectations:
- Identify and build a three-dimensional object from two-dimensional representations of that object.
- Use geometric models to solve problems in other areas of mathematics, such as number and measurement.
