Here, I’m using my blog as a digital filing cabinet.
One activity that my students enjoyed was MATHO (and its variations FACTO and TRIGO).
Have students select and place answers from the bottom of each column to fill up their MATHO cards. In some versions, I pulled prepared questions from a hat. In other versions, I translated answers to questions on the fly. For example, if I grabbed 2√3, I called out “Under the M… the square root of 12”. After a student shouts “MATHO!” ask potential winners to read aloud their numbers. (Remember to keep track of answers you have called.)
Nothing revolutionary here – just a fun way to review content.
