Tenth graders explore geometry with the TI-nspire. In this geometry lesson, 10th graders investigate the menus and tools of the TI-nspire. The lesson includes directions for basic constructions, storing and using measurements, and matrix operations.
Tenth graders explore the basic functions of Cabri, Jr. In this geometry activity, 10th graders practice using the basic functions of the software, including use of the Pointer, Point, Line, Measure, and Construct toolbars.
Tenth graders explore parallel lines cut by a transversal. In this geometry lesson, 10th graders investigate the measures of the angle pairs formed when parallel lines are cut by a transversal. The use of technology allows the student to manipulate the construction and measure the angles to arrive at the correct conjecture.
Students use a number line to assist with their additions. They use a calculator to check for factors. Students are taught factors and multiples. They use array model of multiplication to define meaning. Students develop a wide range of adding, subtracting, multiplying, and dividing strategies.
Tenth graders investigate lines, medians and altitudes. In this geometry lesson, 10th graders answer vocabulary questions and identify parts of a diagram. This assignment contains a printable worksheet.
Here is an introductory lesson to get a sense of the slope of a line, whether positive or negative, and the meaning of the y-intercept. Several examples of changes in slope are shown on a graph and the instructor relates it to how the equation changes to get that line.
In this second video in the series on angles, students explore the concept of supplementary and complementary angles. In addition, intersecting lines and opposite angles are explained.
As a preparation for something called the angle game, a geometry video covers the concept of parallel lines, transversals, slope, opposite angles and corresponding angles. It is the third part of a series detailing the rules and laws regarding angles.
Take geometry into the real world! You'll find just about everything you need for a fun group project reinforcing terms such as: quadrilateral, parallel lines, hexagon, circumference, vertex, acute angle, polygon, and many more. Of course, you can easily add to this 21-term list, which is included in two formats: with definitions and without. Introduce kids to shapes in the world using the attached slide show featuring architectural elements. What geometric concepts do they see? There is an interactive quiz as well as games to reinforce the terms. Then, groups take photographs around campus displaying as many of the words as possible. They create a slide show and present it to the class. If you don't have PhotoStory, PowerPoint will work just fine.
Explore symmetry, in this geometry lesson. View "Line Symmetry," an interactive lesson, fold cutout shapes to find the line of symmetry, and record real objects in the classroom that exhibit a line of symmetry.
Students calculate the surface area of a sphere using the correct formula. In this geometry lesson plan, students differentiate between the surface area of different spheres and make comparisons. They use cylinders with base and non base.
Tenth graders define the properties of tangent and secant lines. In this circles lesson, 10th graders use two lines and a circle to find ways that they relate by illustrations. Students also investigate lines that intersect at the center and lines intersecting inside the circle but not at the center.
Ninth graders discuss the concept of hyperbolic geometry. They complete Internet geometry activities and write essays comparing and contrasting hyperbolic geometry to Euclidean geometry.
Here is a clever, cross-curricular lesson that combines art and geometry. Learners design a painting that uses geometrical shapes and is symmetrical. Sponge-shaped geometrical figures are used to design half a page and fold them to create the other half. Everyone displays their pictures of geometry and symmetry.
For this geometry review worksheet, 10th graders solve and complete 100 various types of problems studied in geometry. First, they find the slope-intercept form of a line passing through two points and parallel to a given line. They also find the length of the leg of a right triangle. in addition, they determine the area of a given quadrilateral.
In this end of the year geometry review worksheet, 10th graders solve and complete 140 different multiple choice problems. First, they find the slope-intercept form of a line passing through a point and parallel to a given line. Then, students determine the transformations that best represent an isometry. They also find the measures of various angles if a triangle within a circle.
In this geometry review set of worksheet, 10th graders solve and complete 139 various types of problems. First, they find the slope-intercept form of a line passing through a point and parallel to a line given. Then, students find the length of the leg of a right triangle. They also determine the area of various quadrilaterals.
High schoolers discuss and identify polygons and lines. In this geometry lesson, learners review liner, square and cubic units so they can incorporate it into the lesson on measurement and creating packing that are cost effective.
In this geometric figures review activity, 10th graders solve and complete 50 various multiple choice problems. First, they find the coordinates of the vertices when a figure is reflected over a line. Then, students name the theorem or postulate that justifies the congruence illustrated. They also find the slope of a line passing through two given sets of points.
Students classify polygons using the correct name based on the number of sides. In this geometry lesson, students identify the different parts of a polygons and differentiate between convex and concave.
