This Grade 3 worksheet has Grade 3 students match real design scenarios to each step of the engineering design process. Using bridges, towers, and rainproof covers as examples, Grade 3 learners connect ask, imagine, plan, create, test, and improve to concrete classroom actions. Fill in the blank practice reinforces vocabulary like criteria, constraint, prototype, and iterate. The matching activity builds Grade 3 reasoning skills and helps students see the design process as a clear and repeatable problem solving tool.

Engineering Design Process
Part A: Fill in the Blank
Write the missing word or number on each line.
1. A Grade 3 class must build a bridge to hold 20 coins. Stating this goal is the ask step.
2. Before building a tower, Grade 3 engineers list rules like height and materials called criteria.
3. A limit such as using only 10 straws for a Grade 3 tower is called a constraint.
4. Grade 3 students draw many rainproof cover ideas during the imagine step.
5. After choosing one rainproof cover idea, Grade 3 engineers make a plan with materials listed.
6. Grade 3 students build a small bridge model called a prototype during the create step.
7. Loading coins on a Grade 3 bridge to see when it breaks is the test step.
8. After testing, Grade 3 engineers make changes, called improve, to make the design better.
9. Repeating the design steps over and over to make a better design is called iterate.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
