11-Plus Non-Verbal Reasoning: Similarities

Understanding Similarities in Non-Verbal Reasoning

In the context of 11-plus Non-Verbal Reasoning, the topic of Similarities involves identifying common features shared by groups of shapes. This skill is crucial for students preparing for the 11-plus entrance exams, as it tests their ability to recognize patterns and apply logical reasoning.

Identifying Common Features

Students are presented with several shapes that belong together based on specific rules or properties. The objective is to determine what these shapes have in common. Common features may include:

• The same number of right angles
• Containing a specific element (e.g., circles or triangles)
• Having a particular type of shading or color
• Similar sizes or proportions

Example of Identifying Similarities

Worked Example

Problem: Consider the following shapes: a square, a rectangle, and a parallelogram. Identify the common feature they share.

Solution:

• All shapes have four sides.
• They can be classified as quadrilaterals.
• Thus, the rule is that they all belong to the category of quadrilaterals.

Practice Questions

To excel in this area, students should practice with various sets of shapes. Here are some practice questions:

1. Which of the following shapes shares a common feature with a triangle, a square, and a pentagon?
2. Identify the shape that does not belong with the others based on the number of sides.

By consistently practicing identifying similarities, students will enhance their spatial awareness and visual problem-solving skills, which are essential for success in the 11-plus exams.
