ASSESSMENT PROPOSAL

Here are the guidelines for assessing written tasks, sent by students.

TASK 1

1 point for: 1o: 12=(1)(1+1)(1+2)/6=1
1 point for: 2o: 12+22+32+...+k2=k(k+1)(2k+1)/6
1 point for: 12+22+32+...+k2+(k+1)2=(k+1)(k+2)(2k+3)/6
2 points for: 12+22+32+...+k2+(k+1)2=(k(k+1)(2k+1)/6)+(k+1)2=((k+1)/6)(k(2k+1)+(k+1))=(k+1)(k+2)(2k+3)/6

TASK 2

2 points for putting the dog's jumps into rabbit ones or the other way round.
1 point for counting the change of distance between them within 6 jumps of a dog or other ways measuring the change
1 point for calculating the ammount of jumps to catching
1 point for the answer x=72.

TASK 3

1 point for assessing the number of students with each of the marks by the use of x
1 point for assessing the number of students with mark: 2
2 points for building the equation of an average value of their marks and solving it.
1 point for the answer x=40.
