Learning Objectives

  • CCSS.MATH.CONTENT.5.NBT.B.6 Find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.
  • CCSS.MATH.CONTENT.5.NBT.B.7 Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.

Guiding Ideas

Explore the following concepts with your class:

1) Can we divide numbers when the divisor is larger than the dividend?

2) How do we divide numbers with decimals

3) How can we use division with crafting?

Watch this video and have the students follow along with pencils and paper.

 

Student Activities

Students will load the attached single player Minecraft world Decimal Dungeon. They will watch videos, observe and build math models, and complete challenges to advance. The world is sequential, but you can warp to any area from the starting Hub. To begin this lesson, speak to the NPC named Level 6.

Level 6) Division with Decimals

Students will divide three crafting recipes to find out how many raw materials it will take to make one stair, slab, and ladder.

Level 7) Performance Task

Students will need to find out how many planks and sticks they will need to craft 20 stairs, 24 slabs, and 18 ladders. There is a book in the treasure chest at the start of Level 7 with more details about the final challenge.

Students will then use the craft table to make the necessary items and place them in the world to escape the Decimal Dungeon!

Challenge 3) Record Your Score

Once you have finished the last level, you end in the safe house. If students have been using the same world throughout the lessons, pushing the buttons will display their score for each section. To record, have students write down your scores on paper and turn it in.

Debrief

1) What kind of number do you get when the divisor is larger than the dividend?

2) What strategies did you use for find out how many planks and sticks were needed to craft 20 stair, 24 slabs, and 18 ladders?

Performance Expectations

1) The student was able to solve division problems with decimals.

2) The student was able to figure out how many planks are sticks are need to make 18 ladders, 24 slabs, and 20 stairs.

3) The student has scores of 2 or higher on all standards.
