Capacity and Volume Exploration

Capacity measurement connects to science (volume) and daily life (cooking), providing authentic mathematical experiences with liquids and solids.

• Framework: Montessori
• Unit: Mathematics
• Learning area: Measurement
• Level: Ages 3-5

Objectives

• Understand capacity as 'how much it holds'
• Compare containers by capacity
• Use non-standard and standard units

Materials

• Various containers
• Water or sand
• Cups for measuring
• Funnel
• Recording sheet

Instructions

1. Present two containers. 'Which holds more?' 2. Estimate, then test: fill one, pour into the other. 3. 'The tall container holds more—it overflowed!' 4. Measure: 'This jar holds 5 cups of water.' 5. Compare several containers. 6. Order from least to most capacity.

Educator tip

Children are often surprised that a tall, narrow container holds less than a short, wide one. This challenges assumptions.

Assessment

Child compares and measures capacity using cups and records findings.
