- 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.

Watch this short video and have the students follow along by writing the problems in their notebooks.

Ask students :

1) How is adding and subtracting decimals different than adding and subtracting whole numbers?

2) How is adding and subtracting decimals the same as adding and subtracting whole numbers?

3) What are real world situations where we would need to add and subtract fractions.

**Warm up:**

Practice the follow problems

1) 1,458.35 + 385.81 =

2) 81.23 - 7.42

Write a word problem.

Students will take the real world situations they just discussed and use them to write a solve a word problem that involves adding or subtracting decimals.

**Play the Game **

Students will enter the world in single player mode watch videos, observer and build math models, and fight monsters. The game will start at coordinate 296 9 19 or you can go to the Hub at coordinate -33 5 69 and chose Level 4. If student have passed this level on day two they should still start at Level 5 with everyone else.

**Challenge 1) Observe and Solve Math Models that Represent Addition and Subtraction Problems with Decimals. **

**Challenge 2) Build a Math Model of Addition with Decimals **

The computer lock will give you two numbers with decimals to add, build the problem and take a picture and document in your portfolio. Then regroup the problem, take a picture and document in your portfolio.

**Debrief **

1) How is adding and subtracting decimals different than adding and subtracting whole numbers?

2) How is adding and subtracting decimals the same as adding and subtracting whole numbers?

3) What strategies can you use to make adding and subtracting with fractions easy.

1) The student was able to observe math models and identify what numbers are being added or subtracted.

2) The student was able to build math models and identify what numbers are being added.

3) The student was able to regroup between place values.
