The Tiger Math series was designed based on my three beliefs toward elementary math education. 1. It is extremely important to build foundation of math by acquiring a sense of numbers and mastering the four operation skills in terms of addition, subtraction, multiplication, and division. 2. In math, one should go through all steps in order, step by step, and cannot jump from level 1 to 3. 3. Practice math every day, even if only for 10 minutes. The goals of Tiger Math Level D - 4 are 1) to practice changing addition to multiplication and 2) to practice and memorize multiplication of 1 digit number by 1 digit number.
