This Logic Unit consists of over 50 of my favorite brain teasers, logic and deductive reasoning activities I have used in my 30 years of teaching math. They are designed to engage the students in critical thinking skills, as well as, getting them to think outside the box. At the same time, they are designed to be fun, so that the students will work to figure out the solutions to develop and strengthen reasoning and logical thinking skills that are essential to math.
I use the activities in the last 15 minutes of class, three times a week. The approach I use is, “vertical learning”, where the students stand to solve the problems. They either use the white board or the windows in the classroom. I get the students to work in partners.
Some problems are short and relatively simple. Others involve multiple steps, and some involve translating a word problem into math terms to solve. Many of the problems contain extraneous information and numbers that are not needed in solving the problem. Practicing these types of problems helps students improve their ability to identify the critical information to help set up the problem to solve.
These activities will help your students to learn and practice the following concepts:
♣ logical reasoning, also known as critical thinking, which involves one's ability to isolate and identify the various components of any given argument.
♣ deductive reasoning is a logical process by which one makes a conclusion based on previously known facts.
♣ a brain teaser is a form of puzzle that requires thought to solve. It often requires thinking in unconventional ways with given constraints in mind; sometimes it also involves lateral thinking.
♣ some of the activities involve writing algebra expressions, where others, students must draw out a picture for a process of elimination.
