- CCSS.Math.Content.3.NF.A.3 Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.

**Getting Started:**

Materials:

- Math notebooks and pencils (colored pencils and graph paper are good for this too)
- Slideshow file
- Whiteboard and markers

Use the slideshow (see Supporting Files) to teach students how to build and explain the math models. Once you have figured this out, you can build these models and project them on the board while your students take notes and write the math in their notebooks.

**The Math Battlefield **

The students will enter the game in Survival mode and with no items and will be trapped on the map. Once all your students have signed on to the game, have everyone get off their computers and sit together by teams, Purple or Gold. Now that your students are away from their computers push the create map button, this will teleport all players to the room where we will choose our teams.

One at a time, a student from each team will go to their computers and walk through the trip wire and teleport into the map with blocks, a pickaxe, the ability to fly, a camera, and portfolio. Because the way the game is coded, it is very important that the students go in one at a time.

Now that the students are in the world, see how many math models they can build, label, and document. A student who is proficient in Minecraft and who gets the concept should be able to complete all three tasks for a math model in about 5 to 10 minutes. Each student should be able to create one to three math models of different equivalent fractions.

See the supporting files section for an example of what the portfolio should look like.

**Peer Review **

Tell students we need to check our work and to fly around and peer review your classmates’ math models. After examining the mode,l label it with the name of the reviewer and the equivalent fractions the reviewer saw. Meaning, if the reviewer saw something different than the creator, there will be different fractions on the sign. Also the reviewer will add on one more equivalent fraction to the math model. So if the review saw ½ = 2/4 = 3/6 the reviewer will add 4/8.

**Play Game **

(See Game Rules Sheet in Supporting Files)

**Debrief Questions **

1. What patterns did you see in the equivalent fractions?

2. Why is ½ the same thing as 4/8ths?

3. What is the difference between a number and an amount?

1. The student was able to build and explain two Minecraft math models that show the relationship between equivalent fractions.

2. The student was able to label their Minecraft math models with correct fractions on signs.

3. The student was able to peer review the Minecraft math models and slates of others to check for accuracy and add another equivalent fraction.

4. The student was able to document their models with pictures in their portfolios.

5. The student was able to add design purpose to their Minecraft math models by using them strategically in the game.

6. The student was able to demonstrate higher level thinking by:

a. Finding number patterns such as: equivalent fractions move in multiples

b. Explaining the difference between a number and an amount
