This math topic focuses on understanding place values of digits within numbers. Specifically, it targets the concept of identifying the numerical value of a specific digit in two-digit numbers, particularly recognizing whether a digit represents units or tens. Each question provides a number and asks learners to determine the value of one of its digits, offering two choices: the digit's value at the units place or at the tens place. This skill helps lay the foundation for more complex number operations and understanding in mathematics.
