Whodunnit? Find out who killed Mr. Brooks through a logical examination of evidence. Class members fill out a couple of data tables to help them pin down the suspect. After they've figured out just who the culprit is, pupils compose...

This a fun problem for young geometers to play with while gaining important insight into deductive reasoning. Some will find the answers very quickly, others might take a less direct path, but all will use their knowledge of the sum of...

Test your pupils' reasoning skills with several activities and a quick mystery to solve. Learners watch and analyze a few video clips that demonstrate reasoning in action, practice deduction with an interactive and collaborative...

Tenth graders investigate deductive reasoning.  For this geometry lesson, 10th graders compare and contrast inductive ns deductive reasoning.  Students use deductive reasoning to investigate algebraic proof and explore...

Explore the process of inductive and deductive reasoning. A collaborative lesson plan has some groups apply an inductive approach and others a deductive approach. Through class discussion, scholars compare their processes and discuss...

Students differentiate between inductive and deductive reasoning. In this geometry instructional activity, students identify congruent figures and examine logos for congruency.

What do Sherlock Holmes and geometry have in common? Why, it is a matter of deductive reasoning as the class learns how to justify each step of a problem. Pupils then present a known fact to ensure that their decision is correct.

This lesson starts out with a guided discussion about the statement "Birds fly in the sky; airplanes fly in the sky; therefore, airplanes are birds" and goes on to cover logical fallacies and reliable sources, relating these to the topic...

Although the methods are all scientific, forensic science was started by police officers rather than scientists, who relied on observation and common sense. Young detectives use many tools to solve crimes around the school in a...

Collect and analyze data. Pupils graph their data and model with it to solve real life problems. They use logic and deductive reasoning to draw conclusions.

Students utilize the scientific method to design a way for a balloon to be suspended between the floor and the ceiling.

Provide your emerging mathematicians with the tools to learn as they incorporate auxiliary lines to solve unknown angle proofs in this continuing segment. They decipher information from a diagram to uncover the missing pieces and...

Sixth graders are introduced to artifacts and explore an online archaeological site to  connect clues about how people once lived. For this deductive reasoning lesson, 6th graders participate in the stratigraphy game on Kids Dig...

Students complete a chain of numbers given the outcome. In this geometry instructional activity, student use deductive and inductive reasoning to solve problems. They create a formula and ways to predict numbers in the chain without...

Twelfth graders define and prove theorems using induction. In this calculus lesson, 12th graders differentiate between inductive reasoning and deductive reasoning. They review sigma notations and work proofs by induction.

Students define inductive and deductive reasoning and write two column proofs. In this geometry lesson, students analyze arguments and draw conclusion. They define steps necessary to arrive at the correct answer when completing proofs.

It's a Pythagorean who-dun-it. Pupils apply the Pythagorean Theorem in several different real-world scenarios involving right triangles. By solving each task, they find the thief who was responsible for a museum heist.

Students investigate triangles and congruences. For this geometry lesson, students differentiate between inductive and deductive reasoning. They differentiate between similar and congruent triangles.

Young geometers apply their deductive reasoning skills and knowledge of proving triangles congruent in a task that asks them to prove if a point lies on the perpendicular bisector of a segment, then it is equidistant from the endpoints...

This activity focuses in on the structure of an equation and how it compares to another. Young algebraists are tasked with grouping together equations that have the same solution by focusing on the transformation of the equations rather...

Students investigate proofs used to solve geometric problems. In this geometry lesson, students read about the history behind early geometry and learn how to write proofs correctly using two columns. The define terminology valuable to...

Learners practice the ability to examine and analyze evidence and extract information that eventually leads to deductive conclusions. After evaluating the objects discovered in a box, students write a one-page reflection paper of their...

What can one learn about a planet based on a small surface sample? Learners will explore artifacts from a mystery planet and see what they can determine about the planet based on the evidence in front of them. 

Students solve a crime mystery using chemical tests. They review the crime scenario and then become familiar with the procedure and results for two tests used to identify unknown powders. They perform the tests on the crime samples and...
