### Learning Objectives

- CCSS.MATH.CONTENT.4.OA.A.2: Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison.1

### Guiding Ideas

The goal of this lesson is to show visuals in Minecraft to prove why and how the multi digit multiplication and long division algorithm works. It is best if the students have had some practice with the algorithms on paper before running this lesson. These math models are a great way to bridge the conceptual and procedural knowledge.

Questions

1) What is multiplication?

2) What kind of problems can multiplication solve?

3) What is division?

4) What kind of problems can division solve?

5) Is there a relationship between multiplication and division?

6) Is there a relationship between the problems they can solve?

Big Idea.

**Multiplication and division can be used to solve real world problems. **

### Student Activities

Students will load the attached world file focused on Word Problems. Students will enter a single player world and solve the four multiplication problems and four division problems. Students will be in survival mode and will be able to fly.

**Challenge 1**

Students will study and build math models to solve four multiplication problems.

**Challenge 1**

Students will study and build math models to solve four division problems.

**Challenge 2 Make a Video **

Students will complete the “Build a Word Problem Worksheet” to prepare for their story problem.

Set up your classrooms with a few quiet areas to record video; sometimes the hallway can work if you have an active class.

As students finish up their problems they will teleport to the exhibition stage and be asked to build a problem. The will solve it on paper and in Minecraft a few times until they feel they understand it well enough to make a video to show their work.

When they are ready, send them to the recording area to a make a video explaining how they solved the problem in under two minutes.

**How to Make a Video **

1. Build the problem.

2. Push the “Windows+G” buttons on your keyboard then the record button.

3. Say your name, say the problem.

4. Solve your problem.

5. Sign off!

**Debrief **

1) What kind of problems can multiplication solve?

2) What kind of problems can division solve?

3) Have students peer review if time allows.

### Performance Expectations

1) The student was able to produce a video of them solving a multi digit multiplication problem or division problem.

2) The student was able to translate between numbers and math models.

3) The student was able to critique and analyze the work of others.

4) The student was able to solve and document all eight problems in the Minecraft Exhibition World.
