IELTS Map and Process Diagram Expression Masterclass

In IELTS Writing Task 1, many students fear map and flowchart questions more than line, bar, or pie charts.

The reason is simple:

• Charts allow you to write about figures.
• Maps require you to describe spatial changes.
• Flowcharts require you to describe steps and sequences.
• Without a rich vocabulary bank, you will often fall back on repetitive words like there is, then, and change.

However, both question types actually follow a fixed pattern. The core of map questions is: Location + Change + Contrast. The core of flowchart questions is: Steps + Sequence + Passive Voice.

This article gathers the most frequently used expressions for IELTS map and flowchart questions. You don't need to memorize complex templates; once you master these basic expressions, your Mini-task 1 writing will become much more stable.

1. What exactly do Maps and Flowcharts test?

First, let's clarify the nature of these question types.

1. What do Maps test?

Maps usually provide one or two maps showing changes in a specific location from the past, to the present, or the future.

Common scenarios include:

• Town center
• School campus
• Park
• Village
• Industrial area
• Shopping mall
• Museum
• Island

The most important aspect of map questions is not to write "all the details," but to grasp the overall changes:

• Is there any expansion?
• Is anything being demolished?
• Are new facilities being added?
• Have functional zones changed?
• Has the road layout changed?
• Have natural areas decreased?

2. What do Flowcharts test?

Flowcharts generally present a process and ask you to describe how something is produced, processed, recycled, or formed.

Common types include:

• Manufacturing processes
• Food processing
• Natural cycles
• Recycling processes
• Water cycle, carbon cycle
• Power generation
• Lifecycle of living organisms

The most important part of a flowchart is writing it clearly:

• What is the first step?
• What stages are passed through?
• What happens at each step?
• What are the inputs and outputs?
• Is it a cycle?
• Are there branches?

2. Most Common Location Words for Map Questions

You must be able to write directions for maps; otherwise, you can only write there is a road, and your sentences will be very monotonous.

1. Basic Directions

• in the southwest: in the southwest part
• in the centre / center: in the center
• in the middle: in the middle

For a more formal tone, you can write:

• in the northern part of the area
• in the southern section of the town
• in the eastern part of the map
• in the western corner of the site
• in the central area

4. Common Sentence Structures for Map Questions

1. Introduction (Paraphrasing the Question)

Question:

The maps show the changes in a town between 1990 and 2020.

You can write:

The maps illustrate how a town changed between 1990 and 2020.

Or:

The two maps compare the layout of a town in 1990 and 2020.

Common openings:

• The maps show changes in...
• The maps illustrate how... changed over the period shown.
• The two maps compare the layout of...
• The diagrams show the development of...
• The maps provide information about changes to...

2. Overview Sentence

Map questions must have an overview. Do not start writing details immediately.

Common sentence patterns:

• Overall, the area became more urbanized.
• Overall, the site was developed significantly.
• Overall, the most noticeable change was the construction of...
• Overall, several new facilities were added, while some natural areas disappeared.
• Overall, the layout changed substantially, especially in the northern part of the site.
• Overall, the area changed from a rural landscape into a more residential district.

Example sentence:

Overall, the town became much more urbanized, with new housing and transport facilities replacing large areas of farmland.

3. Body Paragraph Sentences

• In 1990, there was a large park in the north of the town.
• By 2020, this park had been replaced by a shopping centre.
• To the east of the school, a new sports hall was constructed.
• The road running through the town was widened.
• The original houses were demolished to make way for a car park.
• Meanwhile, the river remained unchanged.
• Another major change was the addition of a railway station.

5. Model Structure for Map Questions

For map questions, it is recommended to write four paragraphs:

1. Introduction: Paraphrase the question.
2. Overview: Summarize the major changes.
3. Body 1: Describe one area or one time point.
4. Body 2: Describe another area or one time point.

Do not write "what you see, you write". There are two more stable segmentation methods:

• By Area: North, South, Center, Surroundings.
• By Change Type: New addition, Demolition, Retention, Expansion.

Sample Framework:

The maps compare the layout of a village in 2000 and 2025.

Overall, the village became more developed, with new residential and commercial facilities replacing farmland and open space.

In 2000, most of the northern part of the village was occupied by farmland, while a small school stood near the centre. By 2025, the farmland had been replaced by a housing estate, and the school had been enlarged.

In the southern section, the original forest was partly removed to make way for a car park and several shops. However, the main road remained in the same location, although it was widened.

6. Most Common Sequence Words for Flowcharts

The first task of a flowchart is to let the examiner understand the order.

1. Starting Stage

• first
• firstly
• initially
• at the first stage
• the process begins with
• the first step is

Example sentences:

The process begins with the collection of raw materials. At the first stage, the clay is dug from the ground.

2. Middle Stages

• then
• next
• after that
• subsequently
• following this
• in the next stage
• once this has been done
• after being processed

Example sentences:

The material is then transported to a factory. Following this, the mixture is heated at a high temperature.

3. Ending Stage

• finally
• eventually
• at the final stage
• the process ends with
• the final product is
• once completed

Example sentences:

Finally, the finished products are packaged and delivered to stores. The process ends with the distribution of clean water to households.

4. Cyclical Processes

• this cycle repeats
• the process is repeated
• the cycle continues
• this stage leads back to the beginning
• the process begins again

Example sentences:

After evaporation, water returns to the atmosphere, and the cycle begins again.

7. High-Frequency Action Verbs for Flowcharts

Flowcharts usually involve production, processing, transport, and treatment. The following verbs are very common.

1. Collection and Preparation

• collect: gather
• gather: collect
• obtain: obtain
• dig: dig
• extract: extract
• sort: sort
• separate: separate
• clean: clean
• wash: wash
• remove: remove

Example sentences:

The raw materials are collected and sorted according to size. Impurities are removed before the material is washed.

2. Processing

• process: process
• crush: crush
• grind: grind
• mix: mix
• blend: blend
• shape: shape
• mould: mould
• press: press
• filter: filter
• purify: purify

Example sentences:

The stones are crushed into smaller pieces. The mixture is then shaped into bricks.

3. Heating and Cooling

• heat: heat
• boil: boil
• melt: melt
• bake: bake
• dry: dry
• cool: cool
• freeze: freeze

Example sentences:

The bricks are heated in a kiln at a high temperature. The liquid is cooled before being poured into containers.

4. Transport and Storage

• transport: transport
• transfer: transfer
• send: send
• deliver: deliver
• distribute: distribute
• store: store
• package: package
• pack: pack

Example sentences:

The finished products are packaged and transported to supermarkets. The water is stored in a tank before distribution.

5. Natural Processes

• evaporate: evaporate
• condense: condense
• flow: flow
• absorb: absorb
• release: release
• grow: grow
• hatch: hatch
• mature: mature
• reproduce: reproduce

Example sentences:

Water evaporates from the surface of the ocean. The eggs hatch and young fish begin to grow.

8. Flowcharts Must Use Passive Voice

In flowcharts, the focus is often not on "who performed the action" but "what the material underwent through the steps."

Therefore, passive voice is very common.

Active: Workers collect the plastic bottles. Passive: The plastic bottles are collected.

Active: Factories heat the mixture. Passive: The mixture is heated.

Common passive structures:

• is / are collected
• is / are transported
• is / are sorted
• is / are cleaned
• is / are crushed
• is / are mixed
• is / are heated
• is / are cooled
• is / are packaged
• is / are delivered

If describing a past process, you can use:

• was / were collected
• was / were transported
• was / were processed

However, most flowcharts describe general processes, so the simple present tense is sufficient.

9. Common Openings and Overviews for Flowcharts

1. Introduction (Paraphrasing the Question)

Question:

The diagram shows the process of making bricks.

You can write:

The diagram illustrates how bricks are produced.

Or:

The diagram shows the stages involved in the production of bricks.

Common openings:

• The diagram shows how... is produced.
• The diagram illustrates the process by which... is made.
• The flow chart shows the stages involved in...
• The diagram explains how... is manufactured.
• The diagram provides information about the production of...

2. How to Write an Overview

For flowcharts, the overview does not need to list every step; it only needs to summarize:

• How many main stages are there?
• Where does it start?
• Where does it end?
• Is it a linear process or a cycle?

Common sentence patterns:

• Overall, the process consists of several main stages, beginning with... and ending with...
• Overall, this is a linear process that starts with... and finishes with...
• Overall, the production of... involves several steps, from... to...
• Overall, this is a cyclical process, as the final stage leads back to the beginning.

Example sentence:

Overall, the process consists of seven main stages, beginning with the extraction of clay and ending with the delivery of finished bricks.

10. Common Sentence Structures for Flowchart Body Paragraphs

1. Manufacturing Process

• At the first stage, raw materials are collected.
• These materials are then transported to a factory.
• After being sorted, they are cleaned and crushed.
• The mixture is shaped into small blocks.
• The blocks are heated in an oven.
• Once they have been cooled, they are packaged.
• Finally, the finished products are delivered to stores.

2. Recycling Process

• Used bottles are first collected from recycling bins.
• They are then sorted according to material and colour.
• After this, the bottles are washed to remove impurities.
• The clean plastic is crushed into small pieces.
• These pieces are melted and formed into new products.
• Finally, the recycled products are distributed for sale.

3. Natural Cycle Process

• The process begins when water evaporates from the sea.
• The vapour rises and condenses to form clouds.
• When the clouds become heavy, rain falls onto the land.
• Some water flows into rivers, while the rest is absorbed by the ground.
• Eventually, the water returns to the sea, and the cycle starts again.

11. Common Pitfalls for Maps and Flowcharts

1. Maps: Using "There is" repeatedly

Low-scoring style:

There is a park. There is a school. There is a road.

Better style:

A park is located in the northern part of the area, while the school stands near the main road.

2. Maps: Missing the Overview

Map questions must summarize the overall changes.

For example:

Overall, the area became more urbanized, with several new buildings replacing open space.

This sentence is more important than a pile of details.

3. Flowcharts: Confusing Tenses

Flowcharts generally use the simple present tense:

The material is collected, cleaned and processed.

Do not switch between present and past tenses.

4. Flowcharts: Too much Active Voice

If there is no person in the diagram, do not force yourself to write workers, people.

The more natural way is:

The bottles are sorted and washed.

Not:

Workers sort and wash the bottles.

5. Detail Lacking Grouping

Task 1 is not a running commentary. Both maps and flowcharts need grouping.

For maps, you can group by area:

• North / South
• Center / Surrounding area
• Old features / New features

For flowcharts, you can group by stage:

• Preparation
• Processing
• Packaging and delivery

13. How to Practice Finally

Maps and flowcharts do not require you to memorize complex templates. A more effective training method is:

1. Spend 1 minute looking at the image to find overall changes or main stages.
2. Write an Overview without numeric details.
3. Divide into two paragraphs based on area or stage.
4. For map questions, focus on checking directional words and change verbs.
5. For flowchart questions, focus on checking sequence words and passive voice.
6. Check for tenses, singular/plural, and articles after writing.

If your foundation is average, first master these four sentence patterns:

• The maps compare the layout of...
• Overall, the area became more developed...
• The diagram illustrates how... is produced.
• Overall, the process consists of several main stages...

Although these sentences are simple, they are stable, accurate, and widely applicable.

During preparation, you can treat maps and flowcharts as a separate Mini-task 1 practice. When you practice writing at Youshow IELTS, you can also use the vocabulary and sentence structures from this article as a checklist: Did you write the directions clearly? Are the change verbs repetitive? Is the process sequence broken? Are the passive voices used correctly?

Official Website: <https://ielts.youshowedu.com> If you are using an iPhone or iPad, you can also search Youshow IELTS directly in the Apple App Store.

Remember the final point:

Maps describe spatial changes, and flowcharts describe process logic.

As long as you keep these two cores clear and fill in your vocabulary and sentence structures according to the list above, Task 1 Mini-task 1 will not be too passive.
