Decomposing Into Equal Addends | Students are presented with an equation and asked to find a pattern within the equation and to determine if the equation is true or not. |

Adding Odd Numbers | Students are asked to consider what type of number results when adding two odd numbers and when adding three odd numbers. |

Adding Odds and Evens | Students are asked to consider the parity of the sums of two even numbers, two odd numbers, and an even and an odd. |

Patterns Within the Multiplication Table | Students are asked to find the missing numbers in a column of a multiplication table by using a pattern found within the table. |

Multiplication of Even Numbers | Students are asked to determine if the total number of students in five classes will be even or odd. |

One with a Bun (Exploring the Multiplicative Identity Property of 1) | In this lesson students will explore the Multiplicative Identity Property of 1, using array and equal-group models for multiplication. Students will model story problems, translate problems into multiplication equations, and identify patterns in a set of multiplication facts to develop understanding of the Multiplicative Identity Property of 1. |

Product Productions | The lesson uses a movie making theme to teach the characteristics and purpose of arrays, as well as the vocabulary, factor and product. |

Arrays Show the Way to the Multiplication Chart | This is an introductory lesson to explore the use of arrays to solve multiplication problems. Students build arrays and save the arrays in a class Multiplication Chart. They learn to use arrays to find products and factors, and by placing them in the Multiplication Chart, they learn how to read the chart. They learn how to write equations to represent situations that are modeled with arrays. An overall theme is the organization of the multiplication chart and how it includes arrays within. |

Efficient Multiplication | Students will engage with questions to evaluate the students' abilities to select and apply multiplication strategies with fluency and efficiency. The focus of the lesson is decomposing numbers to multiply using the Distributive property and understanding and applying the Commutative property. Then, students will reinforce decomposing of factors while playing Decomposition of Factors. The lesson concludes with a real world application problem on an Exit Slip. |

Fall Fun and Games! (Exploring the Commutative Property of Multiplication) | In this lesson, students will build and manipulate a variety of arrays in the context of creating games for a Fall Festival. They will practice using the Commutative Property of Multiplication to find related multiplication facts. |

Apples, Oranges, and Bananas of Math? | In this lesson, the students will work in independently or in small groups to write equations to represent situations as well as their own math riddles around the concepts of multiplication. The teacher will use the book, |
