Logical Reasoning
Logical reasoning is the use of prior knowledge to reach conclusions. In preschool and elementary school,
reasoning and logic are not fully developed so it would be hard to solve problems based on those skills.
In order to develop logical reasoning ability, students must be guided to think about why they got the result they
did and they must be able to explain their thinking.
