Tutor lesson-prep guides · Secondary History

Students can recite 1492 but cannot say why one generation suddenly sailed west. This lesson separates three causes: technology made long voyages repeatable, trade made them profitable, and politics divided the results between two crowns.

Objectives — Students can: (1) order 1492, 1498 and 1519 to 1522 and state what each voyage solved, namely going west, rounding Africa and circling the globe; (2) use a division to explain why Columbus sailed with a wrong figure, since he used about 29,000 km for the globe against a measured 40,075 km, short by 11,075 km or 27.6 per cent; (3) argue that the 1494 Treaty of Tordesillas was political, because two crowns drew a line and claimed future territory without asking anyone who lived there.

01 Prerequisites (3-minute check)

If any of these fails, fix it before the lesson starts.

Skill	Quick check	Pass mark
Timeline	How many years lie between the fall of Constantinople in 1453 and 1492?	39 years, which shows the subtraction and the century are both secure
Prior concept	Why did Europeans want a sea route to Asia?	Land routes passed through too many tax collectors, so spices and silk cost too much
Vocabulary	Why do monsoon winds matter to a sailing ship?	Their direction is regular, so a return voyage can be planned and repeated

02 Lesson flow (45 minutes)

Time	Stage	Tutor does	Student does
0-5 min	Word diagnosis	Ask what the Age of Discovery discovered and write the first answer up uncorrected	Students give their own version, including wrong ones
5-13 min	Three tools	Compass, caravel and monsoon chart, each paired with the problem it solved	Students match each tool to one action it made possible
13-22 min	Ordering the voyages	Hold up three cards for 1492, 1498 and 1519 to 1522 and ask for order and direction	Students order them and name west, round Africa and round the world
22-31 min	The Columbus division	Write 29,000 and 40,075 on the board and ask for the gap and the percentage	Students get 11,075 km and about 27.6 per cent
31-40 min	Silver and spices	Move from the 1494 treaty to the 1565 Manila route and sketch the triangle	Students draw Europe, the Americas and Asia and mark the flows
40-45 min	Exit check	Collect three answers and sort them into correct, partial and wrong	Students hand in three answers

03 Teaching script (read it out)

Scene 1: Script 1: a long voyage is a technology problem before it is a courage problem

You do not reach India by being brave. Three things changed: the compass told a crew its direction far from land, the caravel with lateen sails could work a little into the wind, and monsoon charts told sailors when to go and when to return. Together they turned a one-off gamble into a repeatable route. That is why Dias reached the Cape in 1488 and da Gama reached India in 1498, only ten years apart: once the technology worked, the route could be joined up piece by piece.

Ask students to say in one line which three tools made a voyage repeatable.

Scene 2: Script 2: Columbus sailed on a wrong figure, and that is the best question here

Columbus could calculate, but he used the wrong input. He took the globe to be about 29,000 km across, while it measures 40,075 km, which is 11,075 km short, an underestimate of 27.6 per cent. So he expected Asia within weeks and struck a continent nobody had drawn. Teach the answer as a wrong premise producing an unexpected result, because that sentence scores far better than calling him brave.

Ask students to repeat: Columbus was 27.6 per cent short, so Asia looked much nearer.

Scene 3: Script 3: discovery was followed by division, not exchange

In 1494 Spain and Portugal signed the Treaty of Tordesillas and drew a line down the Atlantic, west for Spain and east for Portugal. Nobody living in those lands was consulted. Da Gama reached India in 1498, Magellan’s fleet circled the globe between 1519 and 1522, 1,082 days on the water, and the Manila route of 1565 linked American silver to Chinese markets. So the textbook word discovery hides three acts: sail, claim, divide.

Ask students to repeat: discovery was followed by claiming and dividing.

04 Question types and worked steps

Type	Example	Steps	Answer
Chronology	Dias reached the Cape in 1488 and da Gama reached India in 1498. How many years apart?	(1) subtract the years (2) state the unit (3) add that the next leg followed within a decade	10 years
Percentage	Columbus used 29,000 km against a real 40,075 km. How far short in per cent?	(1) subtract to get 11,075 (2) divide by 40,075 (3) multiply by 100 and give one decimal	About 27.6 per cent
Causal explanation	Why could Europeans sail the Atlantic at the end of the fifteenth century?	(1) technology: compass, caravel, wind knowledge (2) economics: spice profit, land route costs (3) politics: royal funding and rivalry	All three conditions together turned a gamble into a state project
Evaluation	Is the term Age of Discovery accurate?	(1) name the European viewpoint (2) note that the Americas and Asia were already inhabited (3) judge against a stated criterion	It describes a change in European knowledge, not the experience of local peoples, so it needs quotation marks

Sanity check (teach this): Sanity checks: 1492 minus 1453 must give 39 years, so 49 means a borrowing error; 1488 to 1498 is 10 years, so 20 means adding instead of subtracting; 1522 minus 1519 is 3 years, so 13 means a place value slip; 40,075 minus 29,000 is 11,075 km; 11,075 divided by 40,075 is about 27.6 per cent, so 2.76 per cent means a missing factor of ten; 1494 to 1565 is 71 years.

05 Independent practice (3 questions)

Question	Answer	What to watch
The fleet left on 3 August 1492 and landed on 12 October 1492. How many days at sea?	70 days	Check whether students subtract dates rather than guessing a month
How many years lie between the 1494 treaty and the 1565 Manila route?	71 years	Check both years are handled correctly
Magellan sailed on 20 September 1519 and returned on 6 September 1522. How many days?	1,082 days	Check for real date subtraction rather than three times 365

06 Common mistakes and what to say

Mistake	Student writes	Say this
Discovery told as a single hero story	Columbus discovered America and he was amazing	The remarkable part is that he sailed on a wrong circumference. Say what was wrong: 27.6 per cent short, so Asia looked much nearer.
The three voyages mixed up	All three sailed west to Asia	Da Gama went south-east round Africa, Magellan went west but round South America. Different directions, different results: a route to India, and proof the world is a sphere.
The treaty read as a voyage	They signed a treaty in 1494 so they went exploring	The order is reversed. The treaty came after the sailing and divided property. Two crowns drew a line and claimed other people’s land.
Silver mentioned without direction	America had silver and it went to Europe	Write the triangle: American silver to Europe, European silver to Manila to buy Chinese goods. If goods and people do not move in your answer, marks go missing.

07 Homework (paper, section and question numbers)

History chapter index: this chapter, redo one chronology and one percentage question — Age of Discovery chapter, practice questions 1 and 2
History chapter index: this chapter, write 80 words on why long voyages became possible only in the late fifteenth century — Age of Discovery chapter, practice question 3

08 Exit check (last 5 minutes)

Question	Answer	Decision
What did the 1519 to 1522 voyage prove?	The globe can be circled; the world is a sphere with connected oceans	Answering that it discovered America means the voyages are not separated
11,075 divided by 40,075 is roughly what percentage?	About 27.6 per cent	2.76 per cent means a place value error, so reteach percentages
Why is the 1494 treaty a political act?	Two crowns drew a line and claimed future territory without consulting local peoples	Answering that it helped navigation misses the carve-up

09 Tutor FAQ

Which year group is this for?

S2, and it also works for S1 enrichment or S3 revision, because the target is three layers of cause rather than dates.

Can three voyages fit in 45 minutes?

Yes. The voyages only need ordering and direction. The time goes to the Columbus division and the treaty.

Is there practice attached?

Yes. The chapter index links practice questions with answers on the page, so the tutor can mark at once.
