Core Skills Analysis
Mathematics: Geometry
- BJ identified acute, right and obtuse angles, compared their sizes and ordered angles from smallest to largest.
- BJ examined squares, triangles, pentagons and parallelograms, noticing properties such as the number of sides and the presence of right angles.
- BJ used a Venn diagram to classify shapes by whether they had four sides, at least one right angle, or both, practising how categories can overlap.
- BJ matched equilateral, isosceles, scalene and right-angled triangles to their definitions, building vocabulary for describing triangles.
Spatial Reasoning and Visualisation
- BJ identified and drew lines of symmetry, recognising how a shape can be divided into matching parts.
- BJ reflected shapes across vertical and diagonal mirror lines on grid paper, applying spatial reasoning to determine reflected positions.
- BJ used visual comparison and problem-solving to track how shapes and their features relate across different orientations.
Tips
Tips Extend BJ’s geometry learning with a shape hunt around the home or outdoors: sketch examples and label their angles, sides and symmetry. Invite BJ to build shapes with craft sticks or straws, then sort them in a Venn diagram and explain each placement using precise mathematical vocabulary. For reflection practice, use a small mirror beside grid-paper drawings and predict where each reflected point will appear before checking. Finish with a “triangle detective” challenge: draw several triangles, classify each by its sides and angles, and explain the classifications aloud.
