Class Description: Number Sense is a mental math skill of using arithmetic techniques and brain power to solve math problems quickly. It involves mental computation, computational rounding, and computational estimation without using scratch paper or a calculator. Mental math proficiency is an important aspect of students’ math knowledge, especially for younger students. The speed and accuracy gained from these practices will help students do well in future math classes and math competitions.
Class Format: In each class, the teacher will cover a few Number Sense tricks. Students will get to practice a lot in class.
Number Sense will prepare students for TMSCA Number Sense and MathLeague.org Number Sense contests.
