Math
Cian read about lunar calendars and then used a packet of Oreo biscuits to model the moon’s phases, labeling each phase and arranging the biscuits to show the sequence from new to full. By breaking the biscuits into halves and quarters, he practiced fraction concepts, representing the illuminated portion of the moon as a numerical fraction of a whole. He also compared the northern and southern hemisphere views, recognizing that the same phases appear as mirror images, which reinforced his understanding of symmetry, orientation, and spatial reasoning. This activity showed Cian how mathematical ideas like fractions, patterns, and geometry appear in everyday observations of the sky.
Tips
Encourage Cian to track the real moon each night for a month and record the observed phase on a graph, calculating the average length of the lunar cycle. Have him create a larger 3‑D model using clay or papier‑maché to explore volume and surface area while reinforcing phase shapes. Introduce simple calculations of the percentage of illumination for each phase and let him convert those percentages to fractions and decimals. Finally, set up a mirror‑image activity where he draws the northern‑hemisphere cycle and then reflects it to visualize the southern‑hemisphere view, deepening his grasp of geometric transformations.
