Line Symmetry and Rotational Symmetry
Fifth graders investigate the symmetry of pattern block shapes. Students, working in groups determine whether each shape has line symmetry, rotational symmetry or both kinds of symmetry. Students determine how many lines of symmetry the...

Count on Me
Fourth graders use inductive reasoning to find algebraic patterns in geometric figures. They use technology (i.e., calculators, computers) and manipulatives to discover number patterns involving geometric concepts. They solve concrete...

Vocabulary: Multiple Meaning Words in Context
Learners use context clues to define words with multiple meanings. After extensive practice with their teacher, learners read through six sentences, they then identify a word with a multiple meaning, and determine its meaning based on...

Crystal Growing
Pupils grow crystals and document their observations by recording timeing and growth. Additional characteristics of crystals are observed under a black light, by growing under different conditions and mineral content is determined.

Mapping a Site Using a Coordinate Plane
Learners map their playground as if it were an archeological site. They locate objects on the playground and determine their location using coordinate points. A related lesson plan is Coordinate Grid: Mapping an Archeological Site.

Slippery Slope
Explore slope using geometric patterns. Young mathematicians investigate towers built from cubes to develop a linear pattern. They move the data to a coordinate plane to connect the pattern to slopes.
Curated OER
Relating Algebra to Geometry
Learners investigate the connection that exists between Algebra and Geometry. They classify two and three-dimensional figures. Pupils use formulas to solve problems in geometry and use appropriate measuring devices in the right contexts.

Bubble-ology
Students observe the visible spectrum while observing light hitting the surface of bubbles. They blow large bubbles and observe how the colors change.

An Exploration of the Slope of a Line
Students define the slope of a line. In this algebra lesson, students differentiate between parallel and perpendicular lines using their slopes. They rewrite equations in slope intercept form and explain the meaning of the slope.

Properties of Logarithms
High schoolers explore the concept of logarithms. In this logarithms lesson, students discuss the logarithm properties. High schoolers use linear functions as a basis to develop the logarithm properites by substituting log b...

Maps
Young scholars investigate three types of maps. In this history lesson, students idenitfy different maps and explore how they relate to the area, while keeping climate and topography in mind. They discuss maps used to navigate...

Mesoamerican Carving Project
Third graders are introduced to the use of glyphs and relief carving by Mesoamerican cultures. They complete worksheets, view PowerPoint presentations, participate in a Webquest and create an original glyph carving in sandstone.

Let's Trade
Second graders engage in a instructional activity which focuses on adding two-digit numbers and the regrouping process. They identify when the regrouping process is necessary and make appropriate "trades" to complete an addition problem.
