Learners solve problems using matrices. In this algebra activity, pupils collect data and use matrices to organize their collected data. They interpret the data in the matrices and relate it to different careers, and use addition, subtraction and multiplication of matrices.
In this matrices lesson, students explore the characteristics of a matrix. They identify columns and rows. Students solve matrix problems. They use a matrix to solve a systems of equations. This seven-page learning exercise contains detailed notes. There are five example problems with notes and answers.
Math whizzes explore dilations. They use matrices to perform dilations centered at the origins of triangles and investigate the effect of scale factor on the size relationship between the pre-image and the image of a polygon. A link to all of the various state standards is included.
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. Students dilate, rotate, reflect, and translate the figures by multiplying by translation matrices.
