二年級數學課程：第 1 部分 - 數感與計算技能

This 8-week course is perfect for advanced students in grade one or students in grades 2 and 3 that need further work on number sense and computation skills.  We will meet each week to work on the following skills:  counting, comparing and ordering numbers, addition, subtraction, estimation, problem-solving, and mental math skills. The skills will build from week-to-week with students working with larger numbers and more complex problems.  Students will develop confidence and flexibility when working with numbers and develop a positive mindset and an "I can do it" attitude about math. 
 
Each class will use the following structure:
