#### What is logic in math? It is simply making sense of how things relate. Where math puts numbers or basically quantifies a relation or value, logic is there to clarify its meaning. Logic helps us understand why or how things happen. Hard core quantifying mathematicians will often refer to those that specialize in logic as math philosophers. Which is definitely a neat way to look at it! When we start learning basic math we focus on the language and basic movements of operations. As we start to work with our students at higher grade levels, we are trying to help them develop deductive reasoning skills. A mathematical proof is a math sentence that is used to raise and argument and help the audience come to a logical conclusion of the hypothesis that is set forth. Logic is the root of the structure and presentation of proofs in math. As this evolves further logic statements begin to snowball and develop on their own to become math facts, when through vetted. Computer programs are founded and based on this system of logic. While they may take on different language names, the core reasoning that applies to these worksheets also applies directly to just about every type of computer programming language ever invented.

Below you will find just over 100 logic worksheets that include conditionals, conjunctions, disjunctions, and even Venn Diagrams. Scroll down to find all the worksheet previews. Even though these worksheet topics are organized by alphabetization, they do increase in difficulty as you scroll down. I find the Venn diagram worksheets do require that you have a good understanding of all of these other forms of logic. Please take your time and do not get frustrated with the differing forms of inference tools.

## Conditionals (Using Logic Tables)

These are commonly referred to as if-then math statements. These sentences are only false when the hypothesis is true, and the conclusion is false.

## Conjunctions (Using Logic Tables)

This is when two math sentences are joined into a compound statement. They are usually connected by the word AND. They are only true when both math statements that are joined are true.

## Disjunctions (Using Logic Tables)

These are math statements that are connected by the word OR. The only way these statements are false is if both math sentences are false.

## Converse, Inverse, and Contrapositive

These are three different forms of conditional statements. The converse exchanges the hypothesis and conclusion. The inverse of a statement negates both the hypothesis and conclusion. The contrapositive is a mix of the past two statements we just talked about.

## Truth Values

These indicate whether a math statement is true or false.

## Math Venn Diagrams

We apply this form of graphic organizer to help us chart out our logic statements and systems. The graphic representation that they create can be really helpful for predicting outcomes.
