Median of a Trapezoid
Students find the median of trapezoids and other polygons. For this geometry lesson, students identify important properties of trapezoids. They create trapezoids and polygons using Cabri software.
Curated OER
Tessellations
Students create tessellations. In this geometry lesson plan, students use polygons to create different patterns by rotation. They identify the reasons for polygons to create the type of tessellation it does.
Curated OER
Focus on Friction
The students learn about friction and forces through direct instruction and an investigation. They use measurement skills, observation skills, predicting, and drawing conclusions based on data collected during the investigation. Students...
Curated OER
Using Excel to Draw a Best Fit Line
Middle schoolers create line graphs for given data in Microsoft Excel. Students follow step by step instructions on how to create their graph, including how to create a trend line. Middle schoolers print graphs without trend lines and...
Curated OER
Descriptive Writing
Students create a descriptive paragraph about themselves and use a PowerPoint template to add a picture. Students participate in a brainstorming session of descriptive words to use for their paragraph before beginning their assignment.
