Core Skills Analysis
Mathematics
The student worked with ratios and proportion, comparing two quantities and expressing their relationship as a:b or a/b. They used tables and simple equations to solve real‑world problems such as scaling recipes and calculating distances. By rearranging proportions, they discovered how to find an unknown value when three quantities were known. Throughout the activity the 11‑year‑old practiced converting between fractions, decimals and percentages, strengthening their number sense and logical reasoning.
Tips
To deepen understanding, set up a cooking challenge where the child must adjust a recipe for a different number of servings, recording the new ingredient ratios. Introduce a map‑scale project: have them measure a small drawing of a park and calculate real‑world distances using scale ratios. Organise a “shopping spree” game where they compare unit prices to determine the best value, reinforcing proportion concepts in everyday contexts. Finally, explore the link between ratios and fractions by creating visual fraction bars that represent the same ratio in different forms.
