A short sprint keeps the focus on reasoning.
Successive questions ask children to use different clues and conditions. The review shows which reasoning skills need more practice.
Several hard decisions can fit into a few focused minutes.
The child has to use clues, test possibilities and change course when new information appears.
During the sprint
Each question brings a new set of clues or conditions.
After the sprint
The review points to the reasoning area that needs another pass.
