Engineering Challenge Answer Key

This worksheet features triple-digit addition problems without regrouping, set in an engineering and construction context. Students read about bolts, bricks, concrete blocks, plans, sensors, and building materials. Each problem encourages learners to interpret quantities and compute totals in realistic scenarios. The consistent absence of regrouping allows students to focus on accuracy and number alignment while still tackling large-number addition. This worksheet is excellent for building confidence before progressing to more complex regrouping tasks.
