**Topic: **
| How and when do we round whole numbers and decimals? |

**Content: **
| Rounding whole numbers to different place values and decimals to the nearest tenth. |

**Goals: **
| The student will accurately learn how to round whole numbers and decimals. The game goal is to call bingo as quickly as possible. |

**Materials:**
| Flashcards, whiteboard, handouts, rounding bingo, homework worksheet |

**Introduction:**
| Ask students to make a list of their own opinion on when we should round whole numbers and decimals to see if they have an idea of rounding numbers. Use notes and steps on the whiteboard to explain how to round whole numbers to the nearest ten, hundred, or thousand and decimals to the nearest tenth. |

**Development:**
| Work out several model problems on whiteboard and explain again as each is worked out. Explain how you are doing it and why. Ask students to help to give them a better feel of what you are doing. |

**Practice:**
| Each student will come to whiteboard and work out a few problems so they will get the help they need. Next use flashcards for a quick review of rounding whole numbers and decimals. Then students will divide up in groups for a quick activity for another review of the lesson. Finally if everyone has a good understanding of rounding, the students will play bingo where the numbers on the bingo cards are the results of the decimal being called out. |

**Accommodations:**
| Group 1-students will work out problems rounding whole numbers to nearest ten, Group 2-students will work problems rounding whole numbers to nearest hundred, Group 3-students will work problems rounding whole numbers to nearest thousand, Group 4-students will work problems rounding decimals to nearest tenth. Each group will work on a topic for about 5 minutes then swap up. |

**Checking For Understanding:**
| The students will play "rounding" bingo. |

**Closure:**
| We will once again go over how and when to round whole numbers and decimals. |

**Evaluation:**
| Each student is expected to complete the homework handouts with 80-90% accuracy. |
