2. MS Paint is for drawing and MS Excel is for numbers and tables.

Answer: (a) word. Double-clicking on a word selects that whole word.

Teacher's Note:
1. One click places the cursor, two clicks select a word and three clicks select a paragraph.
2. Practise this on a short line of text to remember it.

Answer: (b) Status Bar. It shows details such as the page number and word count.

Teacher's Note:
1. The Title Bar is at the top and shows the name of the document.

Answer: (a) Dimension. D stands for dimension: 2D means two dimensions and 3D means three dimensions.

Teacher's Note:
1. Dimensions are the directions in which we can measure a shape, like length, width and height.
2. Do not confuse D with degrees, which measure angles.

Answer: (b) Eraser. The Eraser tool rubs out the part of the drawing we drag it over.

Teacher's Note:
1. Remover is not a tool in Paint.

Answer: False. Flat shapes are 2D shapes. 3D shapes are solid shapes, such as a cube or a ball.

Teacher's Note:
1. A flat shape has only length and width.
2. A solid shape also has height, so we can hold it.

Answer: True. Editing changes the content and formatting changes how the text looks.

Teacher's Note:
1. Both editing and formatting are ways of improving a document.
2. Editing is about what is written and formatting is about how it looks.

Answer: False. Formatting means changing only the look of the text, such as font, size, colour or style. Changes to the content itself (adding or deleting words) are called editing.

Teacher's Note:
1. Formatting does not change the words, only their appearance.
2. Do not mix up formatting with editing.

Answer: True. The work area (the white page) is where we type and see our text.

Teacher's Note:
1. The blinking cursor in the work area shows where the typed text will appear.
2. The ribbon above holds the tools, but we type in the work area.

Answer: False. Clicking three times (triple-click) on a paragraph selects it. Two clicks select only a word.

Teacher's Note:
1. Remember: 2 clicks for a word and 3 clicks for a paragraph.
2. Another way is to drag the mouse over the whole paragraph.

Answer: Length, width (breadth) and height (height may also be called depth or thickness).

Teacher's Note:
1. A 2D shape has only length and width.
2. The third dimension, height, makes the shape look solid.

2. Example: MS Word (WordPad is another example).

Teacher's Note:
1. Write the meaning first and then the example.
2. MS Paint is not a word processor because it is used for drawing.

Answer: 1. 2D shapes are flat and have only two dimensions, length and width. Examples: square, circle, triangle.
2. 3D shapes are solid and have three dimensions, length, width and height. Examples: cube, sphere, cone.

Teacher's Note:
1. Always give one example of each kind.

Answer: 1. Formatting text means changing the look of the text in a document.

Teacher's Note:
1. Formatting changes only the appearance of the text.
2. Name at least two formatting options to earn full marks.

Answer: 1. Bigger text is used for headings and titles so that they stand out.

Teacher's Note:
1. A 3 mark answer needs three clear points.
2. Think about how a heading looks different from the normal text in your book.
