To know God and to make Him known.

National Number Knockout

Important Announcement!

Classical Conversations would like to acknowledge the remarkable achievement of our 16 finalists in the 2020 National Number Knockout Competition. Due to health considerations beyond our control, the competition onboard the 2020 Capstone Cruise was cancelled as there was no clear path to safely set a new date in the summer of 2020. Nevertheless, it is imperative to recognize the dedication, determination, and perseverance of these 16 students. We commend and congratulate them on the achievement of being National Number Knockout finalists for the 2019-2020 homeschool year. Our prayer is that God will richly bless these young men and women as they continue to pursue the even greater prize of knowing Him and making Him known. The National Number Knockout Competition currently plans to resume competition for the 2020-2021 homeschool year.

The 2020 National Number Knockout Finalists
Have Been Selected!

From all across the United States, we received numerous entries for the 2020 National Number Knockout Competition. The hard work and effort of each student and parent was evident in each entry which was received this year.

Our team of judges poured substantial hours into watching every single video which was submitted. We carefully noted each problem, we listened intently for how the student solved the board, and we awarded points for each correct problem we could clearly hear. We were dazzled by the problem solving and creativity we encountered.

Though there were many outstanding entries, the judging team was limited to choose 16 students as finalists for this year’s competition. Congratulations to our 2020 National Number Knockout Competition Finalists!

What is National Number Knockout?

National Number Knockout is a nationwide math competition for students, ages 10-14, that culminates in a national championship for 16 finalists on a cruise and a chance to win $10,000. Students interested in entering the National Number Knockout Competition must submit a scouting video by February 23rd at 11:59 EST. This year’s Scouting Board will be announced to the general public on February 10th. The 2020 Prime Advantage membership is no longer available for purchase at this time. For complete rules on how to submit a video and enter the 2020 National Number Knockout Competition, please visit the Scouting Videos page on the main National Number Knockout website.

How Is Number Knockout Played?

Number Knockout is played on a six by six grid of numbers. The classic Number Knockout board contains the numerals 1 to 36. However, the game can be played on a wide variety of boards, and players are encouraged to make their very own boards using a creative selection of numbers and patterns for practice. Number Knockout can be played with many different variations to make the game easier or harder. Because it is so easy to modify the game for a variety of players, it is perfect for students of all ages. For a short video tutorial on how to play, please visit the How to Play page on the main National Number Knockout website.

How Does the Competition Work?

Students between the ages of 10 and 14, who excel at Number Knockout, have a chance to enter the National Number Knockout Competition, which takes place each spring on a cruise ship. Interested students submit a scouting video. Winning students receive airfare and a cruise for themselves and one parent. In addition, the hard-working winner of the competition will also receive the grand prize, which is a $10,000 cash award. While Number Knockout is currently played by students enrolled in Classical Conversations' Essentials program, the competition is open to any and all eligible students. For more information about the competition and eligibility, please visit the Competition Details page on the main National Number Knockout website.

A Game on a Mission

Number Knockout is a fast-paced, mental math game with a mission to “Knock Out Innumeracy.” While many people are aware that illiteracy is detrimental to our society, few people contemplate the long-term effects of innumeracy. According to the 2015 PISA findings, which measures math, science, and reading scores worldwide, the U.S. now ranks 31st among 35 industrialized countries in math proficiency (Barshay, The Hechinger Report). The continuing slide in numeracy skills is concerning for a country that prides itself on our ability to innovate and lead, but Number Knockout is seeking to improve math education in this country by teaching students how to play an easy to learn and highly addictive game.

In addition to knocking out innumeracy by improving students’ mental math abilities, students playing Number Knockout practice speaking and listening to equations. This teaches students innumerable skills beyond mathematics such as accurately speaking the truth, carefully listening for the truth, and graciously defending the truth.
