Decomposing Shapes: EYFS Learning Guide

Comprehensive introduction to decomposing shapes for Early Years Foundation Stage with engaging examples, activities, and visual demonstrations for young learners.

EYFS Focus: Early Shape Understanding
Big Shape = Small Shapes
EYFS Shape Formula
EYFS Learning Objectives:

Recognizing shapes: Identifying squares, rectangles, triangles, and circles in everyday objects.

Exploring properties: Understanding that shapes have different numbers of sides and corners.

Pattern recognition: Seeing how shapes fit together and can be broken apart.

EYFS Key Concepts:

Shape Recognition: Learning to name and identify basic geometric shapes.

Part-Whole Relationships: Understanding that complex shapes are made of simpler parts.

Spatial Awareness: Developing understanding of how shapes relate to each other in space.

EYFS Teaching Methods:
  1. Hands-on exploration: Using manipulatives like blocks, puzzles, and shape sorters
  2. Real-world connections: Linking shapes to familiar objects (pizza slices, windows, etc.)
  3. Play-based learning: Games and activities that involve shape manipulation
  4. Visual demonstrations: Showing how shapes can be combined or separated
Tip 1: Use everyday objects like sandwiches, cookies, or toys to demonstrate shapes.
Tip 2: Encourage children to describe what they see using shape words.
Tip 3: Use songs and rhymes about shapes to aid memory.
Developmental Milestones: Children progress from recognizing shapes to manipulating them.
Learning Goal: Build foundation for more complex geometric concepts.

EYFS Activities: Exercises 1 to 3
1 Simple Rectangle Decomposition
Activity 1
Find the squares in this rectangle:
🟩🟩
🟩🟩
EYFS Focus:

Counting and recognizing: Understanding that a rectangle can be made of smaller squares.

EYFS Activity Method:
  1. Point to the big rectangle
  2. Count the small squares inside
  3. See how 4 small squares make 1 big rectangle
  4. Touch and trace each square

4 Squares in 1 Rectangle
Step 1: Look at the big shape

We see 1 big rectangle made of 4 little squares

Step 2: Point to each small square

Top left square, top right square, bottom left square, bottom right square

Step 3: Count the squares

1, 2, 3, 4 - There are 4 squares!

Step 4: See how they fit together

4 little squares make 1 big rectangle

Step 5: Touch and explore

Feel each square and the big rectangle

1 rectangle = 4 squares
Learning Outcome:

Children learn that big shapes can be made of smaller shapes.

EYFS Principles:

• Concrete learning: Use physical examples and touch

• Counting practice: Develop number sense along with shapes

• Visual exploration: See relationships between shapes

2 Big Triangles
Step 1: Look at the square

We have 1 big square (4 small squares)

Step 2: Draw a line from corner to corner

This cuts the square into 2 triangles

Step 3: Point to each triangle

See the 3 sides of each triangle

Step 4: Compare shapes

1 square became 2 triangles

Step 5: Practice with hands

Trace the lines and shapes with fingers

1 square = 2 triangles
Learning Outcome:

Children discover that shapes can change when we cut them.

EYFS Principles:

• Transformation concept: Shapes can be changed but stay the same amount

• Tactile learning: Use hands to explore shape properties

• Visual demonstration: Show before and after

2 Rectangles
Step 1: Look at the L-shape

It looks like the letter L!

Step 2: Find the tall part

There are 3 squares going up (a tall rectangle)

Step 3: Find the wide part

There are 2 squares going across (a wide rectangle)

Step 4: Count the rectangles

1 tall rectangle + 1 wide rectangle = 2 rectangles

Step 5: Explore with movement

Trace each rectangle with your finger

L-shape = 2 rectangles
Learning Outcome:

Children learn to see complex shapes as combinations of simple shapes.

EYFS Principles:

• Pattern seeking: Look for familiar shapes in complex ones

• Spatial reasoning: Understand how shapes fit together

• Movement integration:
