In this ratio measures worksheet, 10th graders solve and complete 8 different types of problems. First, they find the largest angle of a hexagon. Then, students solve the proportions shown. They also name the similar figures by filling...

Here is a lesson that has learners take a look at corresponding parts of similar triangles, ratios of similarity, reductions and enlargements. They'll manipulate the scale factor (r) to observe the changes in similar triangles and then...

Students Fulfill the requirements of Texas Standards as it relates to math and science. In this circle lesson, students identify the arcs and angles of a circle as it relates to Pi. They solve real life scenarios using space as an example.

Students explore the necessity for standards of measurement and measure length, volume, mass and angles. In this measurement lesson plan, students use their hand and foot to measure objects in the room. They compare their measurements to...

Students engage in a multimedia study of the seasons in relation to the sun's angle of incidence on the Earth as it is tilted on its axis. They interpret satellite maps of the world as they show seasonal changes in plant life.

Students classify lines, slopes and shapes. In this calculus lesson, students calculate the midpoint, segment and equation of a circle. They also review what a slope and angle of inclination is.

Teach your mathematicians how to identify different polygons based on their diagonals. Relating quadrilaterals to the different number of diagonals formed, young scholars use the TI to create a visual of their shape.

In this online interactive reading comprehension activity, students respond to 12 multiple choice questions about Whitman's Leaves of Grass. Students may submit their answers to be scored.

The interactive lesson featured here calls for the use of a Smartboard for sorting and classifying shapes. Then, pupils discuss the rules they followed for sorting their shapes, particularly focusing on the properties of angles. While...
