 * Grade: 4 Unit: 2 Week: 6 Content: Math Dates: 10/22-10/26 **


 * Theme Essential Question: How and when do we apply multiplication and division to solve mathematical problems? **


 * Essential Questions: **
 * How can I generate sequences of the multiples of 2-digit numbers?
 * How can I solve and represent related problems that involve multiples of ten and describe the relationship between the products (e.g., 6x4=24 and 6x40=240, 40 is ten times more than 4, therefore the answer will be ten times more)
 * How can I predict the 10th, 20th, 30th, etc. multiple in a multiple sequence? (If skip counting by 14, the 10th number will be 140, the 20th will be 280, and the 30th will be 420)


 * Standards **
 * ** 4.OA.1 ** Interpret a multiplication equation as a comparison, e.g., interpret 35=5 x 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations.
 * ** 4.OA.2 ** Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison.
 * ** 4.OA.4 ** Find all factor pairs for a whole number in a range 1-100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1-100 is a multiple of a given 1 digit number. Determine whether a given whole number in the range 1-100 is prime or composite.
 * ** 4.NBT.5 ** Multiply a whole number of up to four digits by a 1-digit whole number, and multiply two 2-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.

@http://illuminations.nctm.org/LessonDetail.aspx?ID=L317 This lesson builds on the previous lesson and encourages students to explore another model for multiplication, the familiar set model. Students find products using equal sets and present results in the form of a table. The students apply their knowledge about multiplication in the creation of pictographs @http://illuminations.nctm.org/LessonDetail.aspx?ID=L528 Students examine the role of commutativity and the multiplicative identity, play a multiplication game, and explore products where one of the factors is 6. They also create a "My Personal Multiplication Chart" to record products @http://illuminations.nctm.org/LessonDetail.aspx?ID=L316 In this lesson, students generate products using the number line model. This model highlights the measurement aspect of multiplication and is a distinctly different representation of the operation. The order (commutative) property of multiplication is also introduced. Students are encouraged to predict products and to answer puzzles involving multiplication. @http://illuminations.nctm.org/LessonDetail.aspx?ID=L329 By playing card games and using the The Product Game applet, students practice the multiplication facts. As students continue to master their facts, the teacher closely monitors their progress @http://illuminations.nctm.org/LessonDetail.aspx?ID=L529 Students create multiplication stories where one factor is 6 or 7, and play a multiplication game to help them master their multiplication facts. @http://illuminations.nctm.org/Lessons/Architect/Architect-AS-ProbSolvTasks.pdf This reproducible activity, from an Illuminations lesson, leads students through a series of exercises and questions pertaining to the construction of an originally-designed clubhouse. They are asked to consider how much paint they will need to cover the walls, what they will need to do to make a mosaic floor pattern, what materials they will need for the roof and more. @http://illuminations.nctm.org/ActivityDetail.aspx?id=12 The Factor Game is a fun, interactive game that exercises your factoring ability. You can play against the computer or against a friend @http://illuminations.nctm.org/ActivityDetail.aspx?id=64 With this activity, you can visually explore the concept of factors by creating rectangular arrays. The length and width of the array are factors of your number @http://illuminations.nctm.org/LessonDetail.aspx?ID=L273 Students work in pairs to create their own game boards, a worthwhile challenge. They learn by experimenting and by making mistakes about what factors and products to include in a game @http://illuminations.nctm.org/LessonDetail.aspx?ID=U100 In the [|Factor Game], students start with a number and find its factors. In the Product Game, students start with factors and multiply to find the product. The two games work well together because they help students to see the relationship between products and factors @http://illuminations.nctm.org/LessonDetail.aspx?ID=U150 In this unit, students who have previously studied the meanings of multiplication will use its properties to help them master the products where 6 or 7 is a factor. Mastery will be fostered through class discussions and the playing of games. The unit is most appropriate for students who understand the process of multiplication and have mastered the multiplication facts where 0, 1, 2, 3, 4, and 5 are the factors @http://www.teachersdomain.org/resource/vtl07.math.algebra.pat.lparrange/ In this //Cyberchase// activity, students are given three variations of a problem involving a seating arrangement using rectangular tables. Using manipulatives, they must figure out the patterns relating the number of tables and seats. In each case, they write an algebraic equation that describes the relationship
