#### Lesson Plans

 Name Description Zero on a Hero (Exploring the Zero Property of Multiplication) Students will explore the Zero Property of Multiplication using array and equal-group models for multiplication. Students will model story problems, translate problems into multiplication facts, and identify patterns in a set of multiplication facts to develop understanding of the Zero Property of Multiplication. 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. Let's Multiply using Groups and Arrays In this lesson, students will use pictures in arrays and groups to write multiplication story problems, write an equation, solve the problem, and identify the factors and products. 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. Just Group It Students will be able to use counters to create equal groups and write multiplication equations to represent these representations. Multiply by Multiples of 10 with Number Cubes In this lesson students will use various strategies to multiply one-digit numbers by multiples of 10 within the range of 10-90. The strategies will encompass the Distributive, Commutative, and Associative properties, place value, number lines, base-ten blocks, diagrams, hundreds chart. Students will play a game with number cubes to practice this multiplication. 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. Hungry Zero The definition of the Zero Property of Multiplication will be analyzed, modeled and practiced. Giddy Up, Round Up: Relating Division to Multiplication In this lesson, students will learn to solve division problems by relating them to multiplication facts. Practice materials focus on the 6's and 8's multiplication facts. 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. Pet Store Partitive Division In this lesson students will model partitive division through the real-world activity of a pet store owner. Chip Chip Array! Students work together to create arrays to represent given numbers. Array to Multiply In this lesson, students will understand the concept of arrays and will be able to create/draw an array for multiplication sentences. Engaging center game is used to help students with concrete visual representation of multiplication sentences. Tasty Algebra: Using toasted O cereal to find the missing factor in a multiplication equation. In this lesson students will use Cheerios to solve multiplication equations relating 3 whole numbers from word problems that include missing factors ranging from one through ten. Students will also argue the validity of multiplication equations that include missing factors and products with corresponding word problems. 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, The Grapes of Math by Greg Tang, to support this lesson. Area Isn't Just for Squares This lesson helps students make the connections between area and multiplication using square tiles. How Many Seeds in a Pumpkin? In this hands-on math exploration, students will use knowledge of estimation and multiplication to develop strategies for estimating how many seeds are in a medium-sized pumpkin. Magnificent, Amazing Multiplication Arrays! In this lesson students will be creating, describing, and analyzing arrays as they relate to multiplication. In addition, they will be working on hands on activities that allow them to justify their answers and prove their reasoning.
