1.Question 1 questions: How many blocks was the fence originally? 131 How many blocks did the creepers destroy? 89 Answer: 42 Groups can not advance to the next extension questions unless they have shown two strategies to work this out. (at this point we will accept an algorithm as one)

Extension questions:

2.

After the creepers bombed the fence they then moved onto the building. How many

blocks were left in the building? Question 2 questions: How many blocks were in the building originally? 1233 How many blocks did the creepers destroy? 388

Answer: 845 Groups can not advance to the next extension questions unless they have shown two strategies to work this out. (at this point we will accept an algorithm as one)

3.

James had to use a variety of partial blocks to build the window frames. The creepers

bombed one of these as well. How many blocks were left?

Question 3 questions: How many blocks were in the window frame to begin with? 13.32 How many were destroyed? 0.77 Answer: 12.55

Groups can not advance to the next extension questions unless they have shown two strategies to work this out. (at this point we will accept an algorithm as one)

4.

Using all the information you have, figure out how many blocks James needs to return

his fence and building to the way it was before the creepers arrived? (NB the window frames are included in the building total so dont worry about them)

Answers: Total blocks originally 131 1233 1364

Total blocks destroyed 89 388 477 Answer: 1364 - 477 = 887
