Building With Triangles
Fourth graders use two different techniques to construct triangles with specific dimensions. They determine how to construct nets for three-dimensional objects focusing on those made with equilateral triangles. They are able to name the...
Curated OER
Living in a Geometrical World
Learners participate in a series of hand-on, online, and multimedia activities to examine 2 dimensional and 3 dimensional shapes. They describe common geometric solids. They construct rectangular prisms using straws and ribbon.
Curated OER
Unit on Spepherical Trigonometry
Tenth graders analyze characteristics and properties of two and three dimensional shapes. In this geometry lesson, 10th graders apply Spherical Easel Technology to help them decipher geometric shapes. They compare and contrast the 2D...

Orthographic Drawing
Students investigate orthographic drawings. In this geometry lesson, students identify properties of three dimensional drawings in space. They solve problems using volume and area formulas.
Curated OER
Dimensional Analysis
Twelfth graders examine different dimensions and units which go with a particular dimension. They explore the concept of linear measurement versus area. Students estimate area of 3-D objects. They practice converting from one unit of...
Curated OER
Seeing Seeds
Students identify different types of seeds and label the outside and inside of a seed. Students create their own model of a bean seed.

Why Is An Apple Like A Suitcase?
Students examine a variety of fruit to discover that each has seeds. Through experimentation, they discover the role that fruit and seeds play in a plant's life cycle.
Curated OER
A QUESTION
Students engage in scientifically oriented questions. They give priority to evidence, draw conclusions/formulate explanations and connect/evaluate explanations with scientific knowledge. Students communicate and justify proposed...
Curated OER
Squares to Compare
Students investigate how to draw and classify two and three dimensional figures (squares, triangles, rectangles.)
