Find the area or perimeter of shapes like triangles, rectangles, parallelograms, and hexagons on the coordinate plane. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Find the area or perimeter of shapes like triangles, rectangles, parallelograms, and hexagons on the coordinate plane.

Find the area and perimeter of quadrilaterals using their coordinates. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Students are shown two triangles touching points on a coordinate grid and are asked to answer questions about their perimeters. The purpose of this task is to apply the Pythagorean theorem to calculate distances and areas. Aligns with...

This applet allows users to study the nature of triangles and their area. It draws random triangles on a Cartesian coordinate system. The user can determine the area of the triangle using his or her preferred method. After the calculated...

A ten question test for assessing measurement concepts of area and perimeter. Assessment is scored online and student scores are compared with other students who have taken the assessment. Great assessment tool.

In this activity, students will identify and record ordered pairs from a coordinate plane. They will examine symmetry about the axes, reflections, and symmetry in nature. They understand geometric concepts like area and perimeter, and...
