+# SenseMath: Evaluating Number Sense in Large Language Models
+
+**SenseMath** is a controlled benchmark for measuring whether LLMs can exploit number-sense shortcuts.
+
+## Dataset Description
+
+- **1,600 item families** across 8 categories and 4 digit scales
+- **3 variants per family**: strong-shortcut, weak-shortcut, control
+- **4,800 total items**
+- **Categories**: Magnitude Estimation, Structural Shortcuts, Relative Distance, Cancellation, Compatible Numbers, Landmark Comparison, Equation Reasoning, Option Elimination
+- **Digit scales**: d=2, 4, 8, 16

+
+```python
+from datasets import load_dataset
+ds = load_dataset("DaydreamerMZM/SenseMath", split="train")
