Core Skills Analysis
Math
- Rhydan practised spatial reasoning by matching each geometric piece to its correct position in the picture, using visual information about size, shape, orientation and fit.
- Rhydan explored composition and decomposition of shapes by placing smaller pieces together to form larger picture sections, developing an understanding that a whole shape can be partitioned into several parts.
- Rhydan encountered a variety of two-dimensional shapes, including rectangles, quadrilaterals, triangles, semicircles and other polygonal pieces, and could compare their sides, corners and curved edges.
- Rhydan used mathematical classification and quantity language by noticing groups of pieces with different colours and forms, and by considering how many pieces were needed to complete particular sections of the design.
Tips
Tips: Invite Rhydan to draw each completed picture and label the shapes used, including the number of sides and any curved edges. Next, remove one piece from a section and ask Rhydan to predict which shape is missing before testing the idea. Use paper copies of the pieces to create a new animal, object or abstract pattern, then have Rhydan explain which smaller shapes were combined to make each larger part. For an experiential extension, look around the home for examples of the same shapes in architecture, furniture, signs and packaging, discussing how rotating or reflecting a shape changes its position but not its essential properties.
