# Brainstorm solutions to a problem | Students Compute like Computers to Solve Real Problems (Lesson 5 of 7) | K-2

### Student Objective

Students will be able to:

1. Propose a solution to a problem they have identified and articulated by brainstorming using a digital tool (Padlet)

### Instructions

**Materials Needed:**

- Students will each require a computer
- Interactive Google Slides Activity (google slide 7 and 8)
- Teacher review of how to make interactive activities in google slides
- Students will need a separate mini-lesson on how to manipulate objects in google slides.

**Step 1: Own It – “How do you solve problems?”**

- Think-Pair-Share: Think of a problem you faced before. How do you try to solve it?”
- Exemplar Answer:
- I thought of more than 1 ways to solve it first
- Then I chose one of them I thought worked best

- Scaffold:
- Did you think of one way to solve the problem?
- Did you think of another?
- Did you try one of the ways you thought of?

- Push Thinking:
- How do you know if the solution you thought of would actually solve your problem?

**Step 2: Introduce the Essential Question**

- Say: “Scholars, we continue to answer the question, ‘What steps do computers take to analyze numerical information and find problems that we can solve?'”
- Say: “Today, we will take the fifth step computers take: Brainstorm solutions to a problem”

**Step 3: Review key Terms and Define New Terms**

- Numerical – made up of numbers only
- Situation – an event
- Data – information that is usually made up of numbers only (numerical)
- Bar Graph – a picture that represents our numerical data
- Values – a number that describes the quantity of something
- Solution – how a problem is fixed
- Brainstorm – providing ideas and ways of solving a problem (new)

**Step 4: Review the steps that students have taken so far**

- Include an anchor chart with these steps (as this would represent algorithmic thinking)
- “Over the past few days, we’ve been thinking like computers and taking the steps computers take to find problems.”
- “First, we collected data on an event: the number of marbles students wanted and the number of marbles the teacher had”
- “and we we organized our numerical data”

- Second, we visualized our organized data and turned them into bar graphs”
- Third, we analyzed, or read, our bar graphs to make sure we understand what they’re saying”
- “Fourth, we compared two bar graphs representing an event to discover a problem” (from google slide #7 exemplar)
- We found:
- Students wanted 2 more green marbles than I had in class
- OR: I needed 2 more green marbles to make sure each student got the color marbled they wanted

- We found:

- “First, we collected data on an event: the number of marbles students wanted and the number of marbles the teacher had”

[Check for understanding on the steps students have taken so far. Cold call students to recite a step.]

**Step 5: introduce the Enduring Question**

- “Now last lesson, we identified our problem” –> cold call a student –> stamp it (summarize) –>”So our problem is, ‘Students want 2 more green marbles than the teacher has to give”
- “Today, we ask ourselves the question, “Once I find a problem, how do I try to solve it?”

**Step 6: Introduce and Model brainstorming using a digital collaboration board (Padlet)**

- Introduce brainstorming as part of the fifth step computer takes
- To solve a problem, the first step I take is to brainstorm different ways to solve a problem!
- Define brainstorm:
- Coming up with different ideas to solve a problem

- Model for students what brainstorming is, using the digital board, Padel
- After modelling, have students play around with the digital board to become familiar
- Give them a simple task:
- Write in your favorite color on the padlet board!
- Write in your second favorite color on the padlet board!

- After modelling, have students play around with the digital board to become familiar

**Step 7: Have students brainstorm**

- “Our problem was, ‘Students want 2 more green marbles than the teacher has to give'” (show google slide 7 exemplar)
- “In a moment, you will brainstorm solutions with your partner.
- “Answer this question, ‘How could we solve our problem?'”
- You will post your ideas on the digital board.
- You have [ ] minutes. Go.

**Step 8: Select students to share out there ideas**

- We are not evaluating the validity or feasibility of their responses at this moment

**Step 9: Have students independently brainstorm solutions to a problem (in activity)**

- Provide students their own individualized google slide #8 with their own individual “problem”
- Have students answer the questions to uncover the problem
- Have students “brainstorm” at least 2 ideas on the right side
- Make sure to check in on each student to see that they are brainstorming solutions

**Step 10: Stamp the lesson and preview next lesson: Testing Solutions**

- “Today, we took the 5th step computers make to analyze information and find problems that we can solve:
- we brainstormed solutions to a problem we identified from comparing two bar charts together

- “In the next lesson, we will take the second to last step!
- Test your solutions and see if they solve your problem!
