Geometrical diagrams:

used to represent 2D and 3D shapes

used to communicate shape and size

Statistical diagrams:

used to represent data properties

used to analyze data, conclude and make decision

represent data in bar graph, line graphs, pie charts, and picture praghs

In this topic, there are two main types of diagrams.

Statistical diagrams can be represented visually as picture graphs, pie charts, bar graphs, and line graphs. They represent data and allow us to compare data and make decisions.

Geometrical diagrams can be represented visually as 2d or 3d shapes. They represent real objects and can be used for calculations such as area, perimeter, and volume. They can be drawn in different shapes and sizes for common understanding (e.g draw a circle bigger than a square to show that the square is smaller)

statistical diagrams...

-show data and communicate its propertiies to solve problems

-they help in the process of looking at and understanding the data to make decisions and make conculsions.

-there are a few types of these graphs like bar, line, pie, and pictograms, each with their own pros and cons.

There are 2 main types of Diagrams,

1. Geometrical diagrams

2. Statistical diagrams

So what are they?

1. Geometrical diagrams

Represent and communicate the shape and size of objects to help us solve real-world problems

Are usually 2D or 3D shapes

They are conventions for constructing and interpreting diagrams.

2. Statistical diagrams

They represent data in bar graphs, line graphs, pie charts or picture graphs.

Allow us to analyse data, draw conclusions and make decisions

They have their own special features to represent data

They are conventions for constructing and interpreting diagrams

Represent data and communicate their properties to help us solve problems

# data[].attributes.body
Geometrical Diagrams allow 3D and 2D objects to be drawn on a 2D surface, as well as area, perimeter and volume to be calculated.

Statistical diagrams represent data. There are a few of them, being a bar graph, line graph, pie chart, and a picture graph.

All statistical diagrams allow us to analyze data, draw conclusions, and make decisions.

What Are Diagrams?

Diagrams are visual tools used in mathematics to communicate information clearly. There are two main types: Geometrical Diagrams and Statistical Diagrams.

1. Geometrical Diagrams

Purpose: To communicate the shape and size of objects.

Geometrical diagrams are used to:

Represent real objects - they show 2D shapes and 3D objects in a visual form

Support calculations - using formulae to find Perimeter, Area, and Volume

Conventions (Rules to Follow):

When drawing geometrical diagrams, there are standard conventions:

Lengths - Are they equal? Parallel? Perpendicular?

Angles - What is their size?

2. Statistical Diagrams

Purpose: To represent data, communicate properties, and solve problems — so we can analyse data, draw conclusions, and make decisions.

4 Types of Visual Representations:

Bar Graph - Used to read and compare data across categories

Pie Chart - Shows relative frequency of each category out of the total frequency

Line Graph - Shows how a quantity changes over time

Picture Graph - Uses images to represent data so you can conclude visually

Mind Map: used for brainstorming, note-taking, and organising thoughts

Venn Diagram:highlight similarities and differences between sets of data.

Bar/Column Chart: Compares values across categories.

Pie Chart: Shows proportions of a whole.

There are two main types of diagrams; geometrical diagrams and statistical diagrams.

Geometrical diagrams show size and shape for example for a slice of pizza you would use a triangle to describe in 2D but geometrical diagrams can also describe or show objects or shapes in 3D for example a cube

statistical diagrams are used to represent data and allow us to analyse data easier rather than just reading a write up. an example of a statistical diagram is a line graph,it shows data over the span of a specific amount of time

There are 2 main types of diagrams.

1. Geometrical Diagrams

Used to represent shapes and 3d solid objects

Often used to show real objects

By following certain conventions, we can determine whether a geometrical diagram is a 3d solid or a 2d shape.

Represent and communicate the shape and size of objects to help us solve problems

2. Statistical diagrams

Used to represent data

Examples include bar and line graphs, pie charts and picture graphs

All statistical diagrams allow us to analyse data, draw conclusions and make decisions.

# data[].attributes.body
I learnt that diagrams can be used to represent objects. These diagrams allow us to calculate perimeter, area or volume using formulas.

We also have to follow certain conventions. These conventions help us understand these diagrams. Some of these conventions are:

-Size of angles

-Length of figure

-Sides of equal length

-Lines that are perpendicular

-Lines that are parallel

# data[].attributes.body
Geometrical Diagrams:

-Represents 2D/3D shapes

-Using diagrams to represent objects allows us to calculate their area, volume or perimeter using formulae

-Can be used to represent real objects

-Conventions are used to indicate specific details of the diagram for better interpretation

Statistical Diagrams:

-Represents data, bar graphs

analysis of the properties of data to help solve problems, draw conclusions

Bar graph allows for easy reading

Line graph represents the change in a quantity over time

Pie charts help compare the relationship between different dimensions

Mathematical diagrams:

• Geometrical Diagrams

-- To represent Shapes

-- To represent 3D Shapes/solid objects (Cylinder, Cube, Cuboid)

-- Often used to represent real objects (Rectangle to represent the shape of a football field, circle for a car wheel.

-- Using Diagrams to represent objects allows us to calculate perimeter, area or volume using formulae.

-- For example, using 2D shapes like rectangles and parallelograms to construct a 3D shape like a cuboid.

-- Certain conventions for drawing 2D shapes like indicating the lengths of a figure, indicating a size of an angle, marking the lengths of the sides of equal lengths or marking angles of equal size.

-- Certain conventions for drawing 3D shapes too

-- Summary -> Geometrical Diagrams represent and communicate the shape and size of objects to help use solve problems.

-> There are conventions in Geometrical Diagrams for constructing and interpreting these diagrams.

• Statistical Diagrams

-- They represent data

-- Bar graphs

-> Allows us to read and compare

-> Example: Bar graph of the daily use of residential water per estate (We can read and compare the amount of water used by the different estates)

-- Line graphs

-> Good for showing how one quantity changes over time

-> Example: Height of a mango tree changing over time

-- Pie Charts

-> Communicate relative frequency in each category over the total frequency

-- Picture graphs

-- All statistical diagrams allow us to analyse data, draw conclusions and make decisions

-- Each statistical diagram has its own features that are useful

-- Summary -> Statistical diagrams represent data and communicate their properties to help us solve problems

-> There are conventions for constructing and interpreting these diagrams

Statistical diagrams

Represents data and communicates their properties to solve problems

Helps in the analysis of data to make decisions and draw conclusions

Bar graph - allows for easy reading and interpretation

Line graph - shows how one quantity changes over time

Pie charts - allows for the communication of relative frequencies in each category over the total frequencies

Picture graph/pictographs - allows for easy comparison

Two main types of diagrams:

Geometrical diagrams

To represent 2D shapes

To represent 3D objects

Usually used to represent real items to communicate shape and size to solve problems

Must follow certain conventions to interpret and construct these diagrams

Statistical diagrams

Used to represent data

Use different graphs to do different things, e.g.

Bar graph to compare values

Line graph to track growth

Statistical diagrams allow data to be analysed, conclusions to be drawn and decisions to be made
