High schoolers explore the concept of transformations. In this transformations lesson, students transform figures by reflection and rotation. High schoolers enter the coordinates into lists and transform the lists. Students transform a set of points that create an arrow.
Middle schoolers construct a three-dimensional model of a city using both similar and congruent figures and geometric transformations. City must have at least ten buildings with each building labeled and may be constructed out of paper or modeling clay. A two-dimensional representation, drawn to scale, must be included as well.
Students determine the scale factor of a polygon given an image and pre-image. In this scale factor of a polygon given an image and pre-image instructional activity, students dilate polygons and measure the perimeter and area of the image and pre-image. Students determine the ratios of the two figures and compare it with the scale factor.
Students explore the concept of transformations. In this transformations lesson, students enter data into lists and make a scatter plot of points. Students use lists to transform the data points by shifting the points, left and right, or up and down. Students also enlarge and shrink the data points.
Twelfth graders explore transforming matrices representing figures in the coordinate plane by entering data points of figures such as triangles and quadrilaterals into a matrix. High schoolers dilate, rotate, reflect, and translate the figures by multiplying by translation matrices.
TImath has put together a instructional activity which shows how to use a graphing calculator to manipulate a puppet and make transformations. A good visual as the class manipulates the vectors and sees what happens. They can observe what geometric part are preserved and which parts might change.
