Verifying, Interpolating, and Extrapolating

Property To verify a linear model, substitute a known data point (x, y) into your equation to see if the left side equals the right side. Once verified, you can use the model to make predictions: interpolation estimates values between known data points, while extrapolation predicts values beyond the original data range. Students in Grade 8 learn this as a foundational concept.

Once verified, you can use the model to make predictions: interpolation estimates values between known data points, while extrapolation predicts values beyond the original data range. Predictions made through extrapolation become less reliable the further we move from the original data. Mastering this concept builds critical thinking skills for 8th grade Math.

Yes, Verifying, Interpolating, and Extrapolating is part of the Grade 8 Math standards covered in the Module 5 unit. Students using Reveal Math, Course 3 study this topic in depth. Parents can support learning by asking their child to explain the concept in their own words.
