### Learning Objectives

• CCSS.MATH.CONTENT.5.NF.A.1 Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators.
• CCSS.MATH.CONTENT.5.NF.A.2 Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers.

### Guiding Ideas

1) How do we add and subtract fractions?

2) What is an equivalent fractions?

3) How do we add and subtract fractions with different denominator?

4) What real world situations could adding and subtracting with fractions useful?

5) Teach the algorithm for adding and subtracting with unlike denominators.

### Student Activities

1) Observe Math Models

Students will enter a single player world and observer math models of addition and subtraction of fractions with unlike denominators. There will be help videos that will connect the math models to the algorithm. Once they have made the connection they should enter the next room.

2) Math Model Room

Student will complete and solve problems that involve adding and subtracting with fractions by building math models. They will document their work by taking a picture in their portfolio and making a file with a structure block.

3) Old McDonald Had a Farm: Performance Task

Students will go into the 3rd room to meet Old Macdonald and see his plans for his new farm. They will analyze the plan to determine if the plan will work or not, next they will create a better plan. Last, they will build their plan to prove their math works.

### Performance Expectations

1) The student was able to build and explain math models that represent addition and subtraction with fractions with different denominators.

2) The student was able to use fractions to analyze a plan to divide up the farmland.
