This is a fun digital matching and puzzle assembling activity on solving nonlinear systems of equations. On the first slide there are given a total of 12 problems numbered with 1a,2a,3a,4a,1b,2b,3b,4b,1c,2c,3c, and 4c. On the second slide the answers of the problems are given in random order. Students have to type the number of each problem next to its answer in the empty box provided (matching). There is also a piece of a puzzle corresponding to each answer. Students are asked to copy each p
