Middle School Geometry | Valentine’s Day Activity | Area & Perimeter Project (Slides + Worksheet + Google Slides)
Differentiated Digits by Agnes | Maths for Every Mind

Make Valentine’s Day meaningful and academically rigorous with this engaging Area & Perimeter Geometry Project. Students design their own Valentine’s card using geometric shapes while calculating area, perimeter, and total area with full mathematical working.

This is more than a worksheet — it is a complete, ready-to-teach Valentine’s Day math project pack that combines creativity, geometry, and structured assessment.

💘 What Students Will Do

Students become “Valentine’s Card Designers” and must:

• Create a card using at least 4 geometric shapes
• Include a rectangle, triangle, circle, and heart
• Label all dimensions in centimetres
• Calculate the area of each shape
• Calculate the perimeter (where applicable)
• Show full mathematical working
• Calculate the total area of the card
• Use correct units (cm and cm²)

Students may construct the heart using composite shapes (semicircles + triangle), reinforcing understanding of area of composite figures.

This activity strengthens:

• Area of rectangles, triangles, circles, parallelograms, trapeziums
• Perimeter and circumference
• Composite shapes
• Real-world mathematical application
• Mathematical reasoning and presentation skills

Why Teachers Love This Valentine’s Math Project

• Combines creativity and rigorous geometry
• Ready-to-teach lesson pack
• Includes structured rubric for easy grading
• Supports differentiated learning
• Encourages student ownership and engagement
• Saves hours of planning time
• Works for both print and digital learning
• Reusable every year

Curriculum Alignment

Aligned with:

• Australian Curriculum – Measurement & Geometry (Years 7–8, Stage 4)
• US Common Core
• UK KS3 Mathematics
• IB MYP Mathematics
• Cambridge Lower Secondary
• International math programs

Also works perfectly as a review before teaching surface area, since strong understanding of area of 2D shapes is foundational for 3D geometry.

Turn a seasonal celebration into a powerful geometry lesson.

This Valentine’s Day Area & Perimeter Project transforms standard area practice into a creative, standards-aligned performance task that students will remember, and teachers will reuse every year.
