Engineering Design Process — Answer Key
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
In Grade 3, we pick the very first idea we thinked of during brainstorming.
Corrected: In Grade 3, we pick the very first idea we thought of during brainstorming.
In Grade 3 writing, the past tense of think is thought, not thinked.
2. Fix the sentence:
Grade 3 engineers sketches many ideas before choosing one to build.
Corrected: Grade 3 engineers sketch many ideas before choosing one to build.
In Grade 3, engineers is plural so the verb sketch does not add s.
3. Fix the sentence:
My Grade 3 team brainstormed more ideas than your's during the imagine step.
Corrected: My Grade 3 team brainstormed more ideas than yours during the imagine step.
In Grade 3 grammar, yours is a possessive pronoun and never takes an apostrophe.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. During the imagine step in Grade 3, we brainstorm many different ideas before choosing one.
To brainstorm in Grade 3 means listing many possible solutions quickly.
2. Grade 3 engineers often draw a quick sketch of each idea on paper.
A sketch helps Grade 3 engineers see ideas and compare them before building.
3. It is smart to think of more than one idea during brainstorming in Grade 3.
Having more ideas in Grade 3 gives engineers better choices to pick from.
4. In Grade 3, after we brainstorm, we pick the best idea to plan and build.
Picking one idea lets Grade 3 engineers move from imagine to the plan step.
Part C: True or False?
Read each statement. Circle True or False.
1. In Grade 3, the imagine step means drawing only one idea and building it right away.
True False
In Grade 3, the imagine step is about brainstorming many ideas, not just one.
2. Grade 3 engineers brainstorm lots of ideas so they have many choices before picking one.
True False
Brainstorming many ideas helps Grade 3 engineers find the best solution.
3. In Grade 3, it is wrong to share your brainstorming ideas with your teammates.
True False
Grade 3 engineers share ideas so the team can combine thoughts and pick the best one.
