Deductions in Comprehension B1

Deductions in Comprehension B1

The deductions track in Comprehension B1 begins in lesson 1 and continues through lesson 60. It has three major formats. 
The progression is:

The first format (lesson 1), teaches students how to draw conclusions for three different kinds of draw conclusions for three different kinds of rules:
Every rules: Every person has a skill. John is a person. So, John has a skill.
Some rules: Some people have brown hair. John is a person. So, maybe John has brown hair.
Do not rules: People do not have tails. John is a person. So, John does not have a tail.
The second format (lesson 16) teaches students how to apply two-part rules as in, ‘The faster you finish your work, the more time you have to play. Mary finished her work faster than Bill. Who had mroe time to play?’
The third format (lesson 29) teaches students to figure out the middle step of a deduction. Students are given a rule (every person has a skull) and a conclusion (John has a skull). They learn to construct the middle step (John is a person) by eliminating the words that appear in both the rule and conclusion (has a skull).
