11-Plus Non-Verbal Reasoning: Shape Codes

Understanding Shape Codes in 11-Plus Non-Verbal Reasoning

Shape codes are an essential component of 11-plus Non-Verbal Reasoning, where students must decipher codes that describe various properties of shapes. This skill is crucial for developing spatial awareness and enhancing visual problem-solving abilities.

What Are Shape Codes?

Shape codes consist of letters or symbols that represent specific properties of shapes, such as:

• Number of sides (e.g., triangle, square)
• Colour (e.g., red, blue)
• Size (e.g., small, large)
• Pattern (e.g., striped, dotted)

Students are tasked with interpreting these codes to understand the characteristics of given shapes.

Decoding Shape Codes

To decode shape codes, students must analyze examples where shapes are paired with their respective codes. For instance, a shape might be represented as:

A1: A triangle with 3 sides, blue colour, and large size.

Here, the code 'A1' indicates the properties of the shape. Students must determine what each element of the code signifies and apply this understanding to new shapes.

Encoding Shapes

In addition to decoding, students may also be required to encode shapes. This involves creating a code for a given shape based on its properties. For example:

Shape: A small red circle.

Encoded as: B2 (where B represents 'circle', and 2 indicates 'small red').

Practice Examples

Worked Example

Problem: Decode the shape code 'C3'.

Solution:

• Assume 'C' represents a square.
• Assume '3' indicates a large size.
• Thus, 'C3' describes a large square.

By practicing with various shape codes, students can enhance their ability to quickly and accurately interpret and create codes, which is vital for success in the 11-plus examination.
