Area Introduction with Unit Squares

Covering shapes with unit squares makes area tangible—children literally see how many squares fit inside, grounding the concept before formulas.

• Framework: Montessori
• Unit: Mathematics
• Learning area: Geometry
• Level: Ages 5-6

Objectives

• Understand area as surface coverage
• Measure area with unit squares
• Compare areas of shapes

Materials

• Unit square tiles (1cm²)
• Flat shapes to cover
• Recording sheet
• Grid paper

Instructions

1. Present rectangle. 'How many squares cover the inside?' 2. Place unit squares inside, filling completely. 3. Count squares: 'The area is 12 square units.' 4. Cover different shapes. 5. Compare: 'Which shape has the biggest area?' 6. Notice: 'This shape is 3 rows of 4. That's 12!' 7. Connect to multiplication.

Educator tip

Area = counting squares inside, perimeter = measuring around outside. Distinguish clearly to prevent confusion.

Assessment

Child measures area by covering shapes with unit squares and records results.
