Brainstorming Multiple SolutionsActivities & Teaching Strategies
Active brainstorming helps second graders move beyond single-answer thinking and experience the power of diverse solutions. When students sketch, discuss, and test multiple ideas quickly, they build creative confidence and prepare for real-world problem solving where trade-offs matter.
Learning Objectives
- 1Generate at least three distinct solutions for a given problem, using drawings, words, or simple models.
- 2Compare the potential benefits of two or more proposed solutions, identifying at least one advantage for each.
- 3Evaluate the feasibility of different solutions based on provided classroom materials or constraints.
- 4Explain the purpose of brainstorming as a method for generating a wide range of ideas.

Think-Pair-Share: Ramp Designs
Pose a problem like building a ramp for a marble to travel farthest. Students think alone for 2 minutes and sketch two ideas, pair up to share and add one more each, then share one group favorite with the class. End with a quick vote on most promising ideas.
Prepare & details
Construct several different ideas to solve a single problem.
Facilitation Tip: During Think-Pair-Share: Ramp Designs, set a visible two-minute timer for each phase so students practice rapid idea generation before moving to discussion.
Setup: Standard classroom seating; students turn to a neighbor
Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs
Gallery Walk: Solution Gallery
Each small group brainstorms and posts sketches of five ways to sort classroom recyclables on chart paper. Groups rotate to view others' work, add sticky note comments on benefits, and note feasible ideas. Debrief by selecting top ideas for prototyping.
Prepare & details
Compare the potential benefits of various proposed solutions.
Facilitation Tip: During Gallery Walk: Solution Gallery, post a simple rubric at each station so peers can give specific feedback on functionality and originality.
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Role-Play: Inventors' Pitch
Assign a problem such as a tool to pick up scattered blocks. In groups, students role-play inventors pitching three unique solutions to a 'panel,' using props like straws for demos. Peers ask questions about strengths and constraints before voting.
Prepare & details
Evaluate the feasibility of different solutions given available resources.
Facilitation Tip: During Role-Play: Inventors' Pitch, provide sentence starters like 'My design works because...' to help students articulate their reasoning under time pressure.
Setup: Large wall space covered with paper, or multiple boards
Materials: Butcher paper or large poster paper, Markers, colored pencils, sticky notes, Section prompts
Mind Mapping: Whole Class Web
Project a central problem like improving pencil storage. Students call out ideas as you add branches to a class mind map, then pairs expand one branch with sketches. Discuss and circle top three for further development.
Prepare & details
Construct several different ideas to solve a single problem.
Facilitation Tip: During Mind Mapping: Whole Class Web, use a different colored marker for each branch to visually track how new ideas connect to the original problem.
Setup: Large wall space covered with paper, or multiple boards
Materials: Butcher paper or large poster paper, Markers, colored pencils, sticky notes, Section prompts
Teaching This Topic
Teachers should model brainstorming aloud and deliberately value quantity over quality in early rounds to reduce fear of imperfect ideas. Avoid praising only the 'best' sketch; instead, highlight variety and iteration as strengths. Research in early engineering shows that young students benefit from scaffolded prompts that connect ideas to real constraints like safety or materials.
What to Expect
Students will generate three to five distinct solutions for each problem prompt, share ideas respectfully, and recognize that varied approaches can meet the same goal. Their work will show quick sketches, brief notes, or simple models rather than polished final products.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Think-Pair-Share: Ramp Designs, some students may assume the first sketch they draw is the only acceptable answer.
What to Teach Instead
Remind students that their initial sketch is just one starting point; during the pair phase, they should add at least one new idea inspired by their partner’s work before sharing with the group.
Common MisconceptionDuring Gallery Walk: Solution Gallery, students may believe only the most detailed or colorful poster represents a good solution.
What to Teach Instead
Point out that rough sketches with clear labels often communicate ideas just as effectively; guide students to focus on how each design solves the problem rather than its presentation.
Common MisconceptionDuring Role-Play: Inventors' Pitch, students may think the most elaborate pitch earns the highest score.
What to Teach Instead
Emphasize that clarity and connection to the problem matter most; provide a checklist with 'I solved...' and 'I tested...' to redirect students who focus on performance over substance.
Assessment Ideas
After Think-Pair-Share: Ramp Designs, collect each student’s ramp sketches and ask them to circle the idea they think would be easiest to build. Have them write one sentence explaining their choice.
After Gallery Walk: Solution Gallery, gather students back together and ask, 'Which solution from another group surprised you the most? Why do you think it might work even if it looks different from yours?'
During Mind Mapping: Whole Class Web, listen for students who add a second branch to the web without prompting; note whether they connect their new idea to an existing one or the original problem.
Extensions & Scaffolding
- Challenge: Ask students to combine two of their ramp designs into a hybrid solution and sketch how it would work.
- Scaffolding: Provide pre-cut cardboard pieces or pipe cleaners so hesitant students can manipulate materials before drawing.
- Deeper exploration: Introduce a constraint like 'use only recycled materials' and have students revise their strongest idea to meet the new rule.
Key Vocabulary
| Brainstorming | A group creativity technique used to find a broad range of ideas for a problem. It involves generating many ideas without initial judgment. |
| Solution | An answer or way to fix a problem. For a design challenge, a solution is a plan or object that addresses the problem's needs. |
| Criteria | The standards or requirements that a solution must meet. For example, a solution might need to be safe, strong, or easy to use. |
| Feasible | Possible to do or achieve. A solution is feasible if it can be made or done with the resources available. |
Suggested Methodologies
Planning templates for Science
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerThematic Unit
Organize a multi-week unit around a central theme or essential question that cuts across topics, texts, and disciplines, helping students see connections and build deeper understanding.
RubricSingle-Point Rubric
Build a single-point rubric that defines only the "meets standard" level, leaving space for teachers to document what exceeded and what fell short. Simple to create, easy for students to understand.
