Students locate different conjugated forms of the stem changing verbs merendar, venir, jugar, volver and entender and put the corresponding number in the correct square. Does include the vosotros form. Once they have located all verb forms and every square has a number in it, they sum up the numbers. If the numbers add up to 34 horizontally, vertically and diagonally in all rows, it means everything is correct. If they don’t, something is wrong and the student has to find the error and correct it so that the numbers add up to 34. 34 is the magic number! My students love solving magic squares. It’s fun, yet challenging enough, and self-correcting. Works great for individual practice, and is also the homework that your students will actually want to do! Enjoy!
