**Teacher Name: **
| Mrs. T. Williams |

**Grade:**
| Grade 7-8 |

**Subject:**
| Math |

**Topic: **
| Surface Area of Prisms and Cylinders |

**Content: **
| 1. identify the different faces of 3d figures.
2. calculate the are of each face.
3. find the total surface area. |

**Goals: **
| The learner will understand and use measurements involving 2d and 3d figures. |

**Objectives:**
| 1. identify the different faces of 3d figures.
2. calculate the area of each face.
3. find the total surface area. |

**Materials:**
| paper,pencil, scissors, crayons, glue, 3d patterns |

**Introduction:**
| Determine how much wrapping paper is needed to wrap the present of YOUR choice. |

**Development:**
| Students will count the number of faces used to create a particular prism. They will identify the different faces of a cylinder. students will calculate the area of each face. students will calculate the total surface area. |

**Practice:**
| Students will use overhead 3d figures with given dimensions to calculate the area of each face. They will find the sum of the areas. |

**Accommodations:**
| co-op class will work with partners using 3d manipulatives with measurements to calculate the surface area. |

**Checking For Understanding:**
| Students will construct 3d figures using patterns. They will count the number of faces, measure the edges, calculate the area of each face. find the total surface area. |

**Closure:**
| At the end of this lesson students will be able to identify the different faces of 3d figures. They will know how to calculate the area of 2d figures.They will know to calculate the surface area of prisms and cylinders. They will understand the bigger the prism or cylinder the more wrapping paper is needed to cover it. |

**Evaluation:**
| Students will be assessed on counting edges, faces , and vertices. Students will be assessed on the area of 2d figures. Students will be assessed on the surface area of prisms and cylinders. |
