I used this both for body parts and `Whose is this?` `It`s mine/hers/his.`
Body Parts: students rolled a dice to determin how many eyes/heads/arms/legs etc their monster had.
After drawing the monster, they named and described it to the class.
Whose is this?: students drew a monster, they were then collected and displayed at the front. The students were asked `Whose monster is this?` any student could reply with `It`s ~`s monster.` if no one guessed, the student who drew it would call out `It`s mine!` Remind students NOT to write their name on the sheet.
I have also used a variation, where students each get a monster and have to walk around asking `Whose monster is this?`
