# Math (TAG): Model, Connect, and Solve for Perimeter, Area, and Volume

### Suggested Time Frame: 5 Instructional Days

##### Focus TEKS

Measuring and Calculating Perimeter, Area, and Volume

• 5.4H represent and solve problems related to perimeter and/or area and related to volume. – R RC3
• 5.4G use concrete objects and pictorial models to develop the formulas for the volume of a rectangular prism, including the special form for a cube (V = l x w x h, V = s x s x s, and V = Bh); and – NT
• 5.6A recognize a cube with side length of one unit as a unit cube having one cubic unit of volume and the volume of a three-dimensional figure as the number of unit cubes (n cubic units) needed to fill it with no gaps or overlaps if possible; – S RC3
• 5.6B determine the volume of a rectangular prism with whole number side lengths in problems related to the number of layers times the number of unit cubes in the area of the base. – S RC3
• 7.9C determine the area of composite figures containing combinations of rectangles, squares, parallelograms, trapezoids, triangles, semicircles, quarter circles (R)
##### Computational Fluency TEKS

Multiply and Divide Positive Rational Numbers Fluently

• 6.3E multiply and divide positive rational numbers fluently (R)
##### Spiral Review TEKS

Number Work – (Operations, Order of Operations, Connections to Formulas with Perimeter, Area, and Volume Focus TEKS)

• 5.4B represent and solve multi-step problems involving the four operations with whole numbers using equations with a letter standing for the unknown quantity; – R RC2
• 5.4F simplify numerical expressions that do not involve exponents, including up to two levels of grouping; – R RC1
• 5.4E describe the meaning of parentheses and brackets in a numeric expression; – S RC1

6.7A generate equivalent numerical expressions using order of operations, including whole number exponents and prime factorization (R)
