## Operations & Algebraic Thinking

**Represent and solve problems involving multiplication and division.**

- CCSS.MATH.CONTENT.3.OA.A.3: Students are using the equation P = 2(L+W) – 4 to find perimeter and A = L(W) to find area.
- CCSS.MATH.CONTENT.3.OA.A.4: Students are figuring out the perimeter and area when the length and width have been determined.
- CCSS.MATH.CONTENT.3.OA.B.5: In the Basic House, Farm, and Parthenon lesson plans, students learn are given opportunities to learn about the commutative, associative, and distributive properties of multiplication through the equations for perimeter and area.
- CCSS.MATH.CONTENT.3.OA.D.8: In the Algebra Architecture lesson plans, students are constantly using the four main operations with letters standing for unknown quantities. Students are using formulas to help them solve other formulas.

Having students determine their own dimensions and find the perimeter fulfills many standards in “Operations & Algebraic Thinking” and “Measurement & Data.” |

## Measurement & Data

**Geometric measurement: understand concepts of area and relate area to multiplication and to addition.**

- CCSS.MATH.CONTENT.3.MD.C.5.A: In the Algebra Architecture lesson plans, students are measuring side lengths by blocks, which are essentially unit squares.
- CCSS.MATH.CONTENT.3.MD.C.5.B: Students are measuring length and width to calculate the area of their structure, which can be measured in units squared.
- CCSS.MATH.CONTENT.3.MD.C.6: Students are using improvised units (e.g. blocks) to measure the area, but can easily use units squared. After calculating their area, they can check their work by counting the number of blocks.
- CCSS.MATH.CONTENT.3.MD.C.7.A: After measuring the length and width of their structure, students calculate the area by multiplying the dimensions.
**A = LxW** - CCSS.MATH.CONTENT.3.MD.C.7.B: Students are using whole-number side lengths to find the areas of rectangular structures that can easily be translated to real-life contexts (e.g. architecture).
- CCSS.MATH.CONTENT.3.MD.C.7.D: Since structures in
*Minecraft*are already decomposed into clearly visible units of measurement (blocks), it makes it very apparent that area is additive.

**Geometric measurement: recognize perimeter.**

- CCSS.MATH.CONTENT.3.MD.D.8: In three of the five lessons of Algebra Architecture — Building a House, Farm, and Parthenon — students are solving for perimeter given the measurements of the dimensions of their structures. When given the opportunity to build multiple structures, students can see that different dimensions may have the same area but different perimeters (e.g. 8×5 and 10×4) and vice versa.

Students are learning the formula for area and how it relates to “counting the blocks.” |

# 4th Grade

## Measurement & Data

**Solve problems involving measurement and conversion of measurements.**

- CCSS.MATH.CONTENT.4.MD.A.3: Students are directly using the formulas for area and perimeter to build digital structures, which can be applied to real-life contexts, such as architecture.

# 5th Grade

## Operations & Algebraic Thinking

**Write and interpret numerical expressions.**

- CCSS.MATH.CONTENT.5.OA.A.1: In the house, farm, and Parthenon lesson plans, students use various formulas, including area and perimeter, that contain parentheses; they must be able to evaluate these calculations correctly by applying the order of operations.
- CCSS.MATH.CONTENT.5.OA.A.2: When creating walls or columns, students will understand that finding the number of blocks involves manipulating the perimeter (multiplying and/or dividing the perimeter by a whole-number). By setting up the formula without solving it, students will be able to interpret the numeral expression before solving it.

# 6th Grade

## Expressions & Equations

**Apply and extend previous understandings of arithmetic to algebraic expressions.**

- CCSS.MATH.CONTENT.6.EE.A.2.A: The equations for perimeter (P), area (A), and total number of blocks (Bh) for the basic house contain letters that stand for numbers and will change depending on values of other variables (length, width, height).
- CCSS.MATH.CONTENT.6.EE.A.2.B: When solving the equation for perimeter in
*Minecraft*,**P = 2(L+W) – 4**, students should be able to explain that perimeter is the “product of two times the sum of the length and width, minus four.” They will do this throughout as the lessons challenge students to use language to describe each of the formulas being used.

**Reason about and solve one-variable equations and inequalities.**

- CCSS.MATH.CONTENT.6.EE.B.6: The equations for the basic house, road, farm, and Parthenon lesson plans are comprised of perimeter, area, height, length, width – all mathematical terms that are used in real-life. Furthermore, students begin to build an understanding of how to read algebra as a language where variables stand for unknown numbers.
- CCSS.MATH.CONTENT.6.EE.B.7: In the house, farm, road, and Parthenon lesson plans, students must evaluate expressions in which letters stand for numbers on both sides of the equation (e.g., A = LxW), and build an understanding of the relationship between variables in a given expression.

**Represent and analyze quantitative relationships between dependent and independent variables.**

- CCSS.MATH.CONTENT.6.EE.C.9: Since many formulas used in the house, road, farm, and Parthenon lesson plans involve variables on both sides of the expression (A = LxW, P = 2(L+W) – 4, S = 3L/2), students will see that changing one variable will result in the change of the other variable.

Letters standing for numbers and understanding the relationship between those letters is a key aspect in this lesson plan. |

# 7th Grade

## Expressions & Equations

**Solve real-life and mathematical problems using numerical and algebraic expressions and equations.**

- CCSS.MATH.CONTENT.7.EE.B.4.A: In using the formulas for perimeter and area in the house, farm, and Parthenon lesson plans, students are manipulating the variables to determine their given values. For example, if a student wants to make their Area = 35 and are given width = 5, they must set up the equation to determine what the length would be.
