Today's curriculum give-away is The Fallacy Detective.

What is a fallacy? A fallacy is an error in logic – a place where someone has made a mistake in his thinking.

Logic is sadly missing in this world

Everywhere I turn, TV, popular music, teen peers, I see decisions based on the public view. Logic to me, is a way to counter the tide of evil. It helps people become independent thinkers and better consumers of public opinion.

Looks good for my upcoming 13 year old.

Logic, etc.

My daughter (now 18) learned logic and reasoning from her dad, a Reformed preacher and PhD. He thought it would be a good idea if our children would be able to logically express themselves when faced with defending your faith to atheists or being able to express the reason you believe to someone who wants to know about God and why you believe what you do. It turns out that her cousin, whose parents used to be believers but have fallen away, became involved in evolution but had enough teaching in his younger years to wonder if it was true or not. He started emailing my daughter and she was able to explain logically why she believed God created the world and that Jesus was the savior of the world. Her cousin is a very bright 18 year old who listened because she was able to meet with him on his level through reasoning and logic.
This daughter also was the only one who scored high on the logic part of her math course in college. She is NOT a math major (an English major) and had to work hard, but the logic part was so easy for her that the teacher assumed everyone in the class knew it and said he wasn't going to spend more time on it. Blank looks from the rest of the kids as he moved along forced him to go back and reteach it. It seems that the public schools don't spend much time on this subject. (She was the only home schooled student in the class).

We are in the process of teaching our boys (11,9,7) logic using the Critical Thinking books- Math Detectives, Building Thinking Skills and my seven year old (small learning issues) is taking the Language Arts First Grade curriculum as well as the Math First Grade curriculum. The way these are set up (color, spacing of samples and work area, etc.) is perfect for a child who gets overwhelmed easily by lots of problems in tiny writing with not enough space to work when fine motor skills aren't quite developed.
It also prepares him for reasoning and logic when he gets older.

My son scored low on understanding analogies so I am seeking
curriculum to help him in that area. I think this is a very important skill
and am concerned that we are missing something in what we have done
thus far.

Fallacy Detective

If A then B, if B then C, therefore if A then C isn't that always correct? Did I miss something? Reasoning according to Jay(my 4 year old) as I'm cutting veggies "mom is food good for you?" "yes Jay, it is" ...5 mins later "Mom candy is food so its good for you, can I have chocolate for diner?" "no Jay" After which I have a long debate with said 4 year old about absolute possitives and generalizations (not using those terms) and make a mental note to be more spacific in my answers!

Why it is important to study logic

Studying logic with the Fallacy Detective is one of our favorite things to do as we homeschool. It was fun and entertaining. We are more able to understand the world around us when we study logic, and more able to reason through difficult situations. I would like to win a copy for my grandson.

The Fallacy Detective, curriculum give-away

Logic is an important lesson that is sadly left out of most modern education today. We fall prey to the bombardment of advertising and mis-information on the internet, television, radio, magazines, newspapers, and books when we cannot spot logic fallacies. If we have learned to think, then we can think for ourselves.

I would love to have this book. My eldest child turns 12 this summer, and this would be a good time to start teaching her some logic skills.

Thank you,

People today don't understand logic. We want our children to not make the same mistakes.

Why It's Important to Learn Logic

It's important to learn logic to identify and understand the structure of an argument, to evaluate reasons for the argument, to recognize the validity of each argument, and to put forth the argument in which it also combines one's own beliefs.

Why learn Logic

The Gospel is reasonable but we must learn to REASON. Logic helps our minds be trained. God is LOGICAL; reasonable. "Be ready always to give an answer..."."Come now, let us reason together." says the Lord. God is not the author of confusion. A GREAT reason to learn logic is because the DEVIL HATES IT!

Meg Annunziata

Why it is important to learn logic

It is important because it is linked to truth. God is a God of truth who says, "Come let us reason together." In order to do that, we need to learn how. Needless to say, He will help us with this but he can use materials like these in doing so!

Why Learn Logic?

It is important to learn logic because of the attacks on our faith from both inside and outside of the church. Our children (and we adults) need to be able to identify and combat the logical fallacies used in attacking our faith. It would be nice to have this book to help teach our children more about logic.

Fallacy Detective - Good Title

Although I am an adult, I continue to struggle with the theory that if A=B and B=C, then A=C; this has been completely logical in my mind, but I keep running into issues wherein I have misinterpreted information and people's character.

At the same time, when it comes to my children's education, I am doing my best to raise them to be independent thinkers. I want them to be able to dissect, re-teach, and be able to understand & apply all that they learn from books, videos, teachers, church, friends, wherever they go. I want them to be able to detect when something is incorrect so they can always find the truth and walk in God's best.

All of us could really benefit from this book.
