Features of Timelines

Must have:

A line with dates or times (scale)Information about important events linked to specific datesThe information is short and specific

Can have:TitlePicturesArrows or lines connecting the scale to the informationThe scale can be over a short period of time, or a long one (e.g. one day or a million years)Names, places and technical words

A line with dates or times (scale)

The Scale

A scale on a timeline shows how close events and dates are respective of each other.

The dates placed on a scale should be relative to that place on the scale.

Basic steps of creating a timeline scale

First make a line with start and end dates

Then break the line into smaller sections

Then place dates with important events on the timelineSlide5

Start timeline here

First date isn’t in the timeline

First: Making a line with a start and end date

Step 1:

Identify your first and last date

e.g.

1949

and 1962

Step 2:

Round these numbers

inclusively

to

the tens column (to end in 0)

T

his

means round either up or down to include the original number within the timeline1949

rounds to 19401962 rounds to 1970

First make a line with start and end dates

Then break the line into smaller sections

Then place dates with important events on the timelineSlide6

Yay! First date is within the timeline

1940

will be the start date of the timeline

First make a line with start and end dates

Then break the line into smaller sections

Then place dates with important events on the timeline

Start date will be 1940

End date will be 1970Slide8

Let’s try some ourselves.

Say our start date is 82 and our end date is 91.

How would you round these numbers to the tens and still make sure they were included on the timeline?

What about a start date of 20 and an end date of

29

?Slide9

Step 3:

Draw a line and place your start date on the left side, and your end date on the right side

Step 4

: Find how many years there are between your start date and your end date

-1970 194030

Step 5: Find the factors of this number. Then choose one set of factor pairs to use. Then break the timeline into smaller sections

Step 6

: Break the timeline into sections, using one of the factors of the number of years between the start and end date.

Our chosen factors: 3 and 10 (3 lots of 10 years)

1940

1970

Step 7

: Label these years by using repeated addition.

We are going up in lots of ten years, so we will use repeated addition with tens

First make a line with start and end dates

Then break the line into smaller sections

Then place dates with important events on the timeline

Then break the timeline into smaller sectionsSlide12

Finally, place important dates along the timeline

Step 8

: Place your important dates along the timelineImportant dates:19491955

Creating a scale for a timeline

Make a line with a start and end date

Step 1: Identify your first and last important datesStep 2: Round these inclusivelyStep 3: Draw a line with your and label your start and end dateBreak the timeline into smaller sectionsStep 4

: Find how many years there are between the start and end dateStep 5: Find the factors of this number, and choose one set of factorsStep 6: Break the timeline into sections, using one set of factors you identifiedStep 7: Label these sections using repeated additionPlace important dates along the timelineStep 8: Place your important dates along the timeline using estimationLet’s try some together:
