This math topic focuses on enhancing number sense by requiring students to compute how many more items are needed to make a total of 30. The problems involve various two-digit numbers, all less than 30, and use visual aids such as circles, squares, and triangles of different colors, guiding students toward the nearest tens. Each question presents multiple-choice answers, helping students to practice basic addition and estimate sums up to 30.
