Why is it essential to teach estimation skills?

Teaching estimation skills is essential because it plays a vital role in developing number sense, which is the ability to understand and relate numbers to one another. Estimation encourages students to think critically about numbers and operations, allowing them to make informed guesses about the results of calculations. This skill is particularly important when evaluating answers to ensure they are reasonable; for example, if a student estimates that the sum of two numbers is around 100, but their actual calculation yields 50, they can recognize there is likely an error.

Moreover, estimation helps students become more flexible thinkers, enabling them to approach mathematical problems with a strategic mindset instead of relying solely on precise calculations. This adaptability is crucial in real-life scenarios where exact numbers might not always be available, but quick, reasonable assessments are needed. By fostering these skills, students become more confident in their mathematical abilities and better equipped to solve problems efficiently.
