THIS really needs ultra-careful management.
Doc’s quote-now, it sounds like the Victorian treadmill at first-totally pointless waste of time! But, thinking about it, this has potential. A little development, such as telling them all to number each piece of paper before they finish could be useful.
Then, after number two gets out by rearranging all their pieces of paper back together, teacher reduces the numbers to the same for each kid ie the lowest number a kid has torn up. Teacher then jumbles each kids’ pile & they start together-going home as soon as Teacher’s seen they have rearranged their jumbled pieces into the correct numeric order.
Well, that’s Secondary education, now what about Primary & Infants? I’ll have to give it more thought.
