Tenth graders perform reflections on different geometric shapes. In this geometry worksheet,students define the concept of geometric reflections and find the coordinates of the reflection on a coordinate grid.

Students play various games to help create a classroom community. For this name recognition lesson, students combine their name recognition skills with newly learned art and geometric vocabulary. First students discover vocabulary that...

In this geometry worksheet, students are asked to solve fractions using circles. They divide the circles into different parts and use inequality symbols to identify the parts needed. There are 36 problems dealing with fractions.

Students explore angles and their use in Geometry. Students investigate three different kinds of angles: obtuse, acute, and right angles through an online activity. They identify pairs of angles with special relationships: vertical,...

Students explore how an archaeologist works and makes discoveries. For this archaeology lesson, students participate in a simulation in which they excavate broken pottery. Students use measurement, geometry, and observation skills during...

Students study geometric shapes and practice naming them properly. In this geometry lesson, students work in groups to give definitions of the vocabulary to each other in their own words. Students also visit a lower grade and teach...

Tenth graders plot points on a coordinate plane. In this geometry lesson, 10th graders identify the different quadrants, plots points on a number line and coordinate plane and solve for the midpoint of line segments.

To better understand that the intersection point of two lines lies inside a circle, learners use their keen measurement skills. They discuss arcs, rays, tangent lines, and reflex angles. Then, they put their skills to work as they...

Learn how to identify the diameter and circumference of a circle. Then, collect data on a circle and relate it to the diameter and circumference of a circle. Last, plot data and find the line of best fit.
