• Opportunities to move from targeted drills to complete contest-style tests
• Instruction that helps students develop stronger mathematical reasoning and confidence

Make Number Sense MAKE SENSE.

Successful UIL Number Sense preparation requires more than repeatedly working practice problems. Students also need to understand the mathematical relationships and efficient techniques that allow problems to be solved mentally under contest time limits. The 7 Second Solution: Number Sense Speed Training Workbook combines practice with explanation, helping students turn individual solutions into reusable mental-math strategies.

The warmup quizzes provide concentrated practice for developing skills and recognizing patterns, while the complete tests give students experience applying those skills across a full range of problems. Detailed explanations help students identify more efficient approaches, learn from missed questions, and build the speed, accuracy, and comprehension needed for UIL Number Sense competition.
