Should: Scrambled sentences.

(TESOL Worksheets--Should)

[Cut up the sentences into different cards, and scramble them. Put students into groups of 3 or 4. Give each group a set of cards, a glue stick, and a paper with blank boxes on it.  Students have to glue the words into the boxes to make grammatical sentences.  Each group gets a point for each correct sentence.  The sentences below are the way I originally envisioned this answers, but younger students like to be playful with the language and come up with a variety of answers. ("You shouldn't eat your teacher for dinner", for example.  Also often the students reverse "should" and "shouldn't" for humorous effect.)  I give a point to anything that is grammatical.  Occasionally this results in students not being able to make a grammatical sentence from their left over cards for the last blank, in which case I let them write in their own words with a pen.]
