Geometric Figures-Triangles
Fourth graders explore triangles. In this math lesson plan, 4th graders discuss the different types of triangles. Students create triangles using wiki sticks. Students complete an online matching game.
Curated OER
Slippery Slope
Learners define patterns, relation and function. In this algebra lesson, students find the slope of a line and write equations of line. They model the slope using real life scenarios.
Curated OER
Spaghetti Bridges
Students thread a piece of spaghetti through the holes in the cup. One person suspend the cup by placing each index finger approximately one inch in from the ends of the spaghetti.
Curated OER
Reflections
Students investigate the concept of reflectons. They investigate how an image has a reflection that is symmetrical. They also choose household objects in order to have real life application for finding lines of symmetry.
Curated OER
Reflections of a Linear Function
Students reflect functions about the X-axis, Y-axis, and origin. They derive equations for reflected functions using the website www.explorelearning.com.
Curated OER
Deer Tracks
Students use satellite images to track to movement patterns of deer and examine deer behavior. They write stories about a day in the life of a field scientist.
