Students locate different conjugated forms of the verbs nadar, descansar, trabajar and cantar and put the corresponding number in the correct square. 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, it means everything is correct. If it doesn’t, they have 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 as it is not too difficult, yet challenging enough, and the fact that they are self-correcting saves you a lot of time. Enjoy!
