📐 Area and Perimeter
Children learn to calculate how big a shape is and how far its edge extends. Gaining these concepts helps you become mentally aware and solve things you come across. Math in geometry is also useful when you need to measure places or items around you. By learning about area and perimeter, students start to see the connection between space and length, which is essential for moving on to geometry and measurements in later education.
🔍 What Do We Measure?
Area = the space inside a shape (measured in square units)
Perimeter = the distance around the shape
Simple Formulas
They are taught easy ways to find perimeter (the distance around the outside) and area (the amount of space on the inside). To find perimeter of a rectangle, add its sides together, and to get the area, multiply the length by width. These equations allow children to solve problems in a timely and correct manner. Exploring physical grid paper and making shape models bring a lot of fun and practicality to learning the formulas.
📏 Easy Formulas
- 🟧 Rectangle Area = length × width
- 📐 Rectangle Perimeter = 2 × (length + width)
- 🟦 Square Area = side × side
- 🔲 Square Perimeter = 4 × side
Counting Units
Kids are taught to use square units when measuring area and to use linear units when calculating perimeter. It proves once again that a larger area means a bigger surface, while the perimeter is the outside border or outline. Working on counting units helps children build accuracy and helps them relate math to actual objects. Processing knowledge by covering figures with materials or strapping them helps in practical ways.
🧱 Count the Tiles

Correct Answer: 12 square units ✅
🧩 L-Shape Tile Challenge
How many tiles are in this L-shape?
Correct Answer: 5 square units ✅
Activity Idea
Build the Rule - Use real objects to create and explain patterns (e.g., area = length x width).
Entertainment Activities
1. Formula Matching Game - Match formulas to shapes or tasks.
2. Counting Unit Hunt - Find and count units around the house.
3. Unit Box Builder - Build boxes of equal size and count units in each.
🎓 Recap
✅ Area = inside space (sq units)
✅ Perimeter = outside border (units)
