11-Plus Non-Verbal Reasoning: Differences

Understanding Differences in Non-Verbal Reasoning

The topic of Differences in 11-plus Non-Verbal Reasoning focuses on identifying how shapes within a group vary systematically. This skill is crucial for students preparing for the 11-plus entrance exams, as it enhances their spatial awareness and visual problem-solving abilities.

Key Concepts

Students must learn to identify which property changes across a group of shapes. Common properties to consider include:

• Number of Sides: Shapes may vary by the number of sides they possess. For example, a triangle may be followed by a square, then a pentagon.
• Shading Patterns: Shapes can alternate between different shading styles, such as solid, striped, or dotted.
• Rotation: Shapes may be presented in different orientations, requiring students to recognize the pattern of rotation.

Identifying Variations

When presented with a set of shapes, students should practice the following steps:

1. Examine each shape closely to determine its properties.
2. Identify any systematic changes across the group.
3. Predict the next shape in the sequence based on the identified pattern.

Worked Example

Problem: Consider the following sequence of shapes: a triangle, a square, a pentagon. What is the next shape?

Solution:

• First shape: Triangle (3 sides)
• Second shape: Square (4 sides)
• Third shape: Pentagon (5 sides)

The number of sides is increasing by one with each shape. Therefore, the next shape should be a hexagon, which has 6 sides.

Conclusion

Mastering the concept of differences in Non-Verbal Reasoning is essential for success in the 11-plus exams. Regular practice with various shape patterns will help students develop the necessary skills to excel in this area.
