Mathematics
Victoria used magnetic squares to experiment with nets that could be folded into cubes, which allowed her to visualise the relationship between two‑dimensional shapes and three‑dimensional solids. She identified the six square faces required for a cube and calculated the total surface area by adding the area of each face. By manipulating the magnetic tiles, she practiced spatial reasoning, recognizing how each net could be rotated and reflected before it formed a cube. This hands‑on activity reinforced her understanding of geometry concepts such as faces, edges, vertices, and the properties of regular polyhedra.
Science
Victoria observed how the magnetic squares attracted each other, giving her a practical insight into magnetic forces and the properties of ferromagnetic materials. She noted that the magnets held the squares together securely enough to keep the net stable while she folded it, illustrating concepts of attraction, polarity, and the invisible forces that can hold objects in place. By testing different configurations, she learned that the strength of the magnetic connection can affect the stability of a structure. This experiment linked abstract scientific principles to tangible classroom materials.
Design & Technology
Victoria planned and built a three‑dimensional cube by first designing a flat net with magnetic squares, then iteratively adjusting the layout until it folded correctly. She evaluated which arrangements were most efficient, considering the number of connections needed and the ease of assembly. Through trial and error, she experienced the design cycle of ideation, prototyping, testing, and refinement. The activity cultivated her problem‑solving skills and her ability to communicate design ideas using visual and tactile models.
Tips
Tips: 1) Extend the geometry work by challenging Victoria to create nets for other Platonic solids such as tetrahedrons and octahedrons, comparing surface‑area calculations. 2) Conduct a magnet‑strength investigation where she measures how many squares can be held together before the connection fails, recording data in a simple chart. 3) Introduce a story‑based design brief—ask Victoria to design a cube‑shaped storage box for a specific classroom need, encouraging her to sketch, build, and evaluate the final product. 4) Combine art and maths by having her colour‑code each face of the cube to explore symmetry and patterns.
