Lesson Plan : One Hundred Hungry Ants

**Teacher Name: **
| Jessica Bolen |

**Grade:**
| Kindergarten |

**Subject:**
| Math |

**Topic: **
| Counting to one hundred. Representing equivalent forms of the same number through the use of concrete objects. Uses appropriate problem solving strategies. |

**Content: **
| Numbers, Number systems, and Number Relationships. Mathematical Problem Solving and Communication. |

**Objectives:**
| Students will be able to find different ways to represent one hundred. Students will use problem solving strategies. Students will work cooperatively in groups. |

**Materials:**
| One Hundred Hungry Ants by Elinor Pinczes. Enough manipulatives for each student or small group to have one hundred. I recommend macaroni and borrowing from co-workers. Worksheet to show the combinations. |

**Introduction:**
| Begin by reading students the book One Hundred Hungry Ants. Then explain to students they will be working as the littlest ant. As you read the book for the second time have students move their manipulatives with the story. |

**Development:**
| Teacher should model making guesses about possible amounts and rows. Teacher should show that when the rows do not work out to be equal this is not a combination to record and move on to their next guess. This will help students use problem solving strategies. |

**Practice:**
| After completing all the different combinations made by the littles ant, give students the work sheet to show other possible combinations. Remind students the groups must be equal. |

**Checking For Understanding:**
| Give small groups another number to work with such as 50. Have the group work together to come up with all of the different combinations for 50. |

**Closure:**
| Explain to students that there are many different ways to count things and still come up with the same answer. Review counting by 1's, 2's, 5's, and 10's to one hundred. |

**Evaluation:**
| Students could complete a work sheet at home using this concept, if further evaluation is needed. |
