Geometry Finding Pentominoes
Students explore the characteristics of geometric shapes. In this geometric shapes lesson, students use tiles to draw pentominoes. Students participate in various learning center activities focused on configuring pentominoes.
Curated OER
Reflection
Students examine how some transformations, such as reflections and rotations, do not change the figure itself, only its position or orientation.
Curated OER
Enlightening Explorations, Part II
Sixth graders review their results from the previous experiments. After viewing a kaleidoscope, they make their own pattern on paper and describe the role of light. To end the lesson, they examine light being relfected and refracted and...
