Describing Properties of 2D Shapes (Sides & Vertices)
Identifying and counting sides and vertices of common 2D shapes.
Key Questions
- Compare a square and a rectangle based on their properties.
- Explain why a circle has no straight sides or vertices.
- Construct a shape with three sides and three vertices.
National Curriculum Attainment Targets
About This Topic
Plant structures focus on the anatomy of flowering plants and trees. Year 1 pupils learn to identify and describe the basic parts: roots, stem (or trunk), leaves, and flowers. This aligns with the National Curriculum target for pupils to identify and describe the basic structure of a variety of common flowering plants, including trees.
This topic is not just about naming parts but understanding their roles, such as how roots anchor the plant and soak up water. It provides the vocabulary needed for more advanced biological studies. This topic comes alive when students can physically model the patterns of water transport and plant growth through hands-on experimentation.
Active Learning Ideas
Simulation Game: The Human Plant
Students act out being a plant. Feet are 'roots' (wiggling to find water), the body is the 'stem' (standing tall), and hands are 'leaves' (catching sunlight). This kinesthetic activity reinforces the function of each part.
Inquiry Circle: Celery Straws
In small groups, students place celery stalks in colored water. They predict what will happen and then observe how the 'stem' transports the water to the leaves over the course of the day.
Think-Pair-Share: Flower Power
Show photos of very different flowers (e.g., a sunflower and a tiny grass flower). Pairs discuss why they look so different and what the job of the flower might be (attracting bees).
Watch Out for These Misconceptions
Common MisconceptionStudents often think that plants 'eat' soil.
What to Teach Instead
Explain that soil provides minerals and a place to stand, but plants make their own food in their leaves using sunlight. A 'Sunlight Catchers' activity helps illustrate the role of leaves.
Common MisconceptionChildren may believe that the roots are only there to hold the plant up.
What to Teach Instead
The celery experiment is perfect for correcting this, as it visually proves that the roots and stems are like straws that drink water.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
