This worksheet set gives students meaningful practice with decimal operations in real-world contexts. The first activity focuses on purchasing snacks for a field trip, where students find the subtotal, calculate sales tax, apply a coupon, and divide the final cost among a group. The next task challenges them to compute the surface area of a rectangular storage box using decimal measurements, exclude areas that aren’t painted, and determine the total paint needed and cost.

Another section asks students to use decimal grids to model addition visually and apply regrouping to show how tenths and hundredths combine to form whole units. Students color and shade portions of 10×10 grids, making this an excellent bridge between visual models and computation. The final part introduces the idea of equivalent division by scaling both the dividend and divisor, helping students understand why multiplying both numbers by the same factor does not change the quotient. They practice making division easier by choosing helpful factors, then explain what happens when only one part of a division expression is scaled.

The included answer key provides step-by-step reasoning for every problem, making this resource strong for classwork, small groups, homework, or review.
