| Error Type | Description | Likely Cause | Suggested Intervention | |------------|-------------|--------------|------------------------| | | Student writes the sum without adding the carried digit (e.g., 68 + 47 = 105). | Weakness in place‑value alignment. | Conduct a “place‑value board” activity where students physically move tens and units blocks. | | Incorrect unit conversion | Writes 3 m 20 cm = 3 20 cm (i.e., 320 cm) but records “3.20 cm”. | Confusion between decimal notation and metric conversion. | Review the relationship “1 m = 100 cm” using visual strips of paper. | | Shape mis‑identification | Labels a sphere as a cube. | Insufficient exposure to 3‑D solids. | Use real‑world objects (e.g., a ball, a dice) for a “shape‑hunt” in the classroom. | | Graph misreading | Picks the tallest bar but misreads the label, choosing the wrong pupil. | Over‑reliance on visual height, ignoring axis labels. | Practice “read‑the‑axis first” strategy with guided questions. | | Word‑problem calculation error | Adds 45 + 27 = 72 correctly, but writes 71 due to a slip. | Inattention to the final digit. | Encourage a “double‑check” habit: re‑add using a different method (e.g., counting on). | Instead, it offers a descriptive analysis of the
