Polygons and Sketching
In this geometry worksheet, students define and draw quadrilaterals. They differentiate between the different shapes. There are 3 questions with an answer key.
Curated OER
Ship Shape
Second graders explore shapes. After reading books about shapes, 2nd graders describe the properties of various shapes. They identify shapes if they have been rotated, flipped, or slid. Students create shapes using drawings and geoboards.
Curated OER
Exploring the Slopes of Parallel and Perpendicular Lines
Students calculate the slope of parallel and perpendicular lines.In this algebra lesson, students differentiate between parallel and perpendicular lines. They graph their lines using the slope of the equation.
Curated OER
Exploring the Slopes of Parallel and Perpendicular Lines.
Students find the slopes for perpendicular and parallel lines. In this geometry lesson, students differentiate between parallel and perpendicular lines. They use Cabri software to create lines to compare.
