11-Plus Non-Verbal Reasoning: Building Blocks

Building Blocks in 11-Plus Non-Verbal Reasoning

The topic of Building Blocks in 11-plus Non-Verbal Reasoning focuses on counting and visualising 3D constructions made from cubes or blocks. This area is essential for developing spatial awareness and visual problem-solving skills, which are crucial for success in the 11-plus entrance exams.

Understanding 3D Block Constructions

Students will encounter questions that require them to assess various 3D constructions. These constructions may consist of visible and hidden blocks, challenging students to think critically about the total number of blocks present.

Key Skills Developed

• Counting Blocks: Accurately determining the total number of blocks in a given structure, including those that are not immediately visible.
• Visualisation: Imagining the construction from different angles to understand its full structure.
• Modification: Assessing how many blocks need to be added or removed to achieve a specific target shape.

Types of Questions

Questions related to Building Blocks may include:

• Identifying the total number of blocks in a complex structure.
• Visualising how the structure would appear from various perspectives.
• Determining the number of additional blocks required to form a new shape.

Worked Example

Problem: A construction is made up of 5 visible blocks stacked in a pyramid shape. If there are 3 hidden blocks at the base, how many blocks are there in total?

Solution:

• Visible blocks: 5
• Hidden blocks: 3
• Total blocks = Visible + Hidden = 5 + 3 = 8

Preparation Tips

To excel in this topic, students should practice regularly with 3D block construction exercises. Using physical blocks or drawing diagrams can help in visualising the structures better. Additionally, familiarising oneself with different types of questions can enhance problem-solving speed and accuracy.
