Core Skills Analysis
Mathematics
Megan practiced addition and subtraction of whole numbers, strengthening her ability to combine and separate quantities accurately. She applied mental strategies such as counting on and using number bonds, which helped her develop fluency with basic operations. By checking her work with inverse operations, Megan reinforced the relationship between addition and subtraction. This activity also gave her confidence in handling multi‑digit calculations appropriate for her age.
Tips
Encourage Megan to solve real‑world word problems that require both addition and subtraction, such as budgeting a small allowance or planning a simple event. Introduce her to number line activities where she can visually see the impact of adding and subtracting, deepening conceptual understanding. Have her explore different strategies—column method, lattice, and mental math—to discover which works best for her and to build flexible problem‑solving skills. Finally, integrate technology by using interactive math games that adapt to her progress and keep practice engaging.
