History · Grades 2–5
Timelines, order and duration
Knowing which event came first does not by itself tell you the time gap.
Understand the idea
Separate order and duration
Knowing which event came first does not by itself tell you the time gap.
Read the scale
Timeline spacing represents time only when a scale is provided.
Use the stated convention
These exercises use positive numbered years unless specified.
Worked examples

Try it yourself
Which sequence is in chronological order?

- 1902, 1835, 1810
- 1835, 1810, 1902
- 1810, 1835, 1902
Why can two events drawn close together on an unscaled timeline still be many years apart?
Which evidence could help date an old letter?

- the envelope's current price
- a dated postmark
- the nicest handwriting

Answers and marking notes
Answers and marking notes
- 1810, 1835, 1902
The years increase from earliest to latest.
- Without a consistent time scale, visual distance does not reliably represent duration.
Credit the need for labels or scale.
- a dated postmark
A postmark can provide a relevant date, though context still matters.
- 7
2011 − 2004 = 7.
