Matrix Equations - Matching and Answering Questions Activity

This is an engaging teacher and board themed activity on solving matrix equations. There are four problem pages/slides. On the first page/slide, students are given four matrix equations of types A+X=B, X-A=B and A-X=B. Students are also given the answers and have to type the number of each problem next to its answer (matching). The matrices are of 2X2 dimensions. On the second page/slide, students are given three matrix equations of the same types as the matrices are 3X2, 2X3 and 3X3 dimensions. This time students have to answer three questions concerning the answers (like what is the sum of the elements of the obtained matrix X of problem 1). On the third page/slide, students have to solve 4 matrix equations of types AX=B and XA=B. They will need to find the inverse matrix of the matrix A and them to multiply A^(-1)B or BA^(-1). Students are given the answers and have to match each problem with its answer. And on the fourth page/slide, students have two matrix equations of types AX=B and XA=B as the matrices are of 3x3 dimensions. After solving the equations students are asked two questions concerning the obtained answers (like what is the sum a11+a22+a33 of the elements of the matrix X of problem 1). Students type their findings in empty boxes provided.

This activity can be completed individually or students can work in pairs.

Answer keys are included.

NOTE: This product is created as a Google Slides product. I have converted it to PDF item here. I have included 2 PDF files - the one has each slide as a page and the other has two or three slides on a page for easy and more economic printing!
