Classmates apply midpoint concepts by leapfrogging around the complex plane. The 12th lesson in a 32 segment unit, asks pupils to apply distances and midpoints in relationship to two complex numbers. The class develops a formula to find...

Discover how to find a midpoint with a conceptual exploration. Scholars manipulate a point to determine the location of a midpoint on a straight line distance between two locations. Later questions extend to determine the...

Students calculate the distance formula. In this geometry activity, students find the distance between two points on a coordinate plane. They identify the four different quadrants.

Students calculate the midpoint of a line. In this geometry instructional activity, students identify the different parts of the coordinate plane. They use the midpoint formula to find the middle of segments between a pair of coordinates.

Ninth graders investigate quadrilaterals.  For this geometry lesson, 9th graders examine and classify quadrilaterals using the slope, midpoint and distance formulas.  Additionally, students create various quadrilaterals given...

High schoolers explore the concept of right triangles as they construct a right triangle using Cabri Jr. Learners find the midpoint of the hypotenuse and construct a line from the midpoint to the vertex of the right angle. They then...

High schoolers explore the concept of quadrilaterals as they find the midsegments of quadrilaterals using Cabri Jr. on a graphing calculator. They find midpoints, slopes, angles, and distances of lines and angles.

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

Students calculate the are of regular polygons. In this geometry lesson, students create polygons on the computer and move it around to create different shapes. They explore the area of different polygons and how they inter-relate.

Students solve real life situation using the Pythagorean Theorem. In this geometry instructional activity, students calculate the length, midpoint and slope of segments. They solve word problems using properties of square roots.

Pupils calculate the perimeter of shapes. For this geometry lesson, students relate properties of polygons to the real world. They find length, midpoint and slope.

Students identify different polygons. In this geometry lesson, students name polygons using the number of sides. They calculate distance and slopes using the correct formula.

Young scholars identify the properties of different polygons. In this geometry lesson, students find the slope of a line and calculate the distance between two lines. They differentiate between similar and congruent polygons.

Students define vocabulary words. In this geometry lesson, students identify the graph as a line, ray or segments. They understand the properties of each and calculate the distance on a number line. 

Students utilize triangulation techniques to determine altitudes of objects. An altitude locator is constructed and used to determine the height of a building or a tree. Tangent tables and formulas provide the ratio for the formula to...

Learners explore the concept of concurrent lines in triangles. In this concurrent lines in triangles instructional activity, students work in groups to investigate properties of concurrent lines in acute, right, and obtuse triangles....

Students calculate the slope of the equation In this algebra instructional activity, students graph coordinate pairs of linear equations and identify the relationship between x and y values and slope.  They differentiate between...
