Homeschool Success through a Classical Approach

Updates and Revisions

Year 1, Year 2, Year 3 will be renamed Tour I, Tour II, Tour III with each new chapter cycle. Being back at Year 1 is a great time to make this change. This is to emphasize that these are three cycles and to distance us from an association with levels or grades. This is only a change in titling, not a change of content.
Thank you for joining Catholic Schoolhouse! Catholic Schoolhouse has been an apostolate, sharing our labors of love since 2009. Since then we have seized every opportunity to make Catholic Schoolhouse the best it can be. Because of this, there are a few different editions (dignified by their copyright date) floating around. It is our hope to help you sort out the difference with this page!
The only significant  revision that should cause you to need new editions was during the creation of the CDs from 2012-2014. We do not recommend purchasing books with a copyright prior to 2013 on the used market.
We have created this page to help you save the expense of purchasing new editions.

Tour I

Current stock is 2013/2014 editions, matches the cd. 2017 edition is planned for release February 2017.

2012 edition is prior to the cd’s and does NOT have the history sentences included in it. Other content is similar, but the cd wording may not match in other subjects as well.

Tour I CDs

The following are being rerecorded for revision on the 2017 cds.

  • Week 2: St. Augustine founded 1565. (not 1566)
  • Week 5, 6: Intros updated to Saint Junipero Serra!
  • Week 9: The adverb song changed to match the 2016 Year 3  CD. The adverb song had been oversimplified. It now includes the phrase “other adverbs.”
  • Week 15: Science, tune is the same, for clarity and technical accuracy wording changed to: “In the circulatory system, the heart pumps blood away through arteries to the capillaries and brings blood back to the heart through veins.”
  • Week 15: Language, same tune. Who changed to whom
  • Week 21: Geography song was updated. Mt. McKinley is now officially known as Denali per President Obama’s declaration.
  • New Latin recordings to correct the pronunciation of Principio and others.

Tour I Tour Guide

  • W22 Typo–  Forgive us our debtors, not out debtors.

Corrections that were made from 2013 to 2014 for those with older 2013 editions:

I no longer have this copy. If someone has one of these editions and would like to help make a list here, we would love to give you a new edition of the Tour Guide for your work.

In a few early printings, the abbreviations for Alaska/Arkansas were switched. It has been corrected.

Tour I History Cards

Freedom of the Press-1733: Alexander Hamilton corrected to say Andrew Hamilton, no relation to Alexander.  — Resolved in 2016 Printing.

Card 16 – Thirteen Colonies: Omitted card number has been added.

State History – The last three weeks of Tour I have always been reserved as a place to study your state history, therefore there were no history cards for these weeks. In the new Tour I edition (2017) fill-in-the-blank style cards have been added to assist you.


Tour II

Current stock is 2013/2014 editions, titled Year 2. 2017 edition is planned for release as soon as we finish our Tour I work. No later than January/February 2018 when our chapters cycle back to Tour II.

  • Week 9: The adverb song had been oversimplified. It now includes the phrase “other adverbs.”

Year 3 (Tour III) History Cards

Card 8 – Vasco da Gama – Corrected text (some editions state that Calicut later became known as Calcutta, which is not true. Calcutta is a different city in Northeast India.

Rounding the cape was difficult. Remember, Dias had wanted to call it the Cape of Storms for a reason. After several tries, Vasco da Gama succeeded and sailed on, landing in Calicut, a town on the West coast of India famous for its spices and cloth. It is possible that our word calico (a woven cotton cloth) comes from this famous city.

Card 17 – Clarified confusion with dates 1519 and 1521. 1519 is the most important date to memorize, as that is when the majority of the events occurred.

Cortés Defeats the Aztecs.

Cortés Battles the Aztec Civilization- 1519

In 1519, as the Spanish explored what is now Mexico, they were led by Hernán Cortés, a bold and wealthy soldier known as a conquistador.

After arriving in the New World, Cortés had his ships burned so his men could not turn back. This ensured that they remained loyal and ready to fight! Cortés quickly realized that the Aztecs and their king, Montezuma, were the wealthiest inhabitants of this land. Their Pagan rituals were shocking to the Catholic explorers.

Throughout 1519, Cortés’ men battled the Aztecs, taking their leader Montezuma captive. Their advantage of guns, along with immunity to European diseases, greatly reduced the Aztec population. With the help of rival civilizations, the Aztec capital, Tenochtitlan, was destroyed in 1521.

Mexico City was built on Tenochtitlan’s ruins. Today, when someone travels to Mexico and gets sick, it is called Montezuma’s revenge.

Card 90 Eiffel Tower – clarification – While the jamming referenced was strategically important to WWI, the reference to the flag and Hitler are from WWII. The middle paragraph will be re-written:

In 1914 (WWI), powerful jamming transmitters were installed on the tower. During WWII, German soldiers climbed the 1710 stairs to place a swastika on the tower; every time it was replaced in the night with a French flag. This resulted in the saying, “Hitler conquered Paris, but he never conquered the Eiffel Tower.”

Year 3 (Tour III) CDs

The new 2016 edition of the cd’s will have the following changes:

Quarter 1

  • 10 Commandments song shortened to take out the repetition. Same song, just shortened to remove duplication. Some of you will miss the repetition, but many, many said by the end of the semester they just couldn’t take it any more! Shortened 10 Commandments song
  • Week 1 Science: New Song – Monera was mispronounced on the 2013 cd. Correct pronunciation is moh NAIR an, rather than MON er a.

Quarter 2

  • Week 9: The adverb song (language arts/grammar week 9) had been oversimplified. It was rewritten to include the phrase “other adverbs.” Link to new adverb song
  • Week 9 Geography: Several requests from members resulted in a new song for W9. a) The Bahamas are not technically part of the Caribbean.  b) the song could be better if put in geographical order.  c) There is no island called “Caribbean” so that was just kind of hanging out there. 2016 edition will have a brand new improved song with the countries in geographical order for easier memory: Cuba, Jamaica, Haiti, Dominican Republic, Puerto Rico, Dominica, Grenada, and Trinidad.  Link to new Caribbean Islands song 

Quarter 3

  • Week 13 Science. Song has been changed for accuracy and clarity. Gravity is an acceleration, not a rate as the original song said. New song words: Gravity is the force which causes all objects to accelerate toward earth at 9.8 meters per second squared.
  • Classical Roots Week 15: Typo – Lithos (year) should be lithos (stone). Yes, lithos and petros both mean stone. lithos is Latin, petros is Greek.

Quarter 4

  • Week 20 history: While not a mistake, wording was changed for consistency. The Panama Canal was completed in 1913, opened in 1914. All products are being updated to “opened 1914.”

These three years, with 24 weeks, and 10 subjects contain an enormous amount of material! We are ever grateful for the many, many eyes, ears, and minds that have reviewed, pre-read, and offered their suggestions!! Please continue to make this, your Catholic Schoolhouse apostolate, better and better.

Praise be to God!
