-__Never use group grades.__ -Begin with tasks which are easy even for the lowest achiever, so he gets the expectation he/she can succeed. -__Positive interdependence plays a large role in success. "Sink or Swim as a group"__ -Individual accountability is also a big part of the group, you must be expected to contribute to the group as an accountable member.

//The ideas of sink or swim together, and no group grades, do not really go hand in hand. Which is interesting, because although students holding themselves accountable helps the group, not all will, so the other students should be expected to help them. Yet that also causes an unequal balance because that student is now doing twice the work.//

Ability grouping? - personally disagree, High achiever mixed with low achievers and given suitable tasks is probably the better set up, to avoid uneven balance within groups. Maybe grouping is what leads to even distribution. If we evenly split kids, then we know there will be kids in each group able to handle certain tasks.
 * How to group the kids is an important aspect of the learning.**
