The Meanings Of MultiplicationTeacher- Jeremy AngelosLength- 5 DaysWeymouth Public Schools

Teacher Goals/Standards I will introduce multiplication to the students by teaching

them strategies they will need in order to come up with a product of multiplying two numbers.

Common Core State Standards 3.OA.1- Interpret products of whole numbers, e.g. interpret 5X 7

as the total number of objects in 5 groups of 7 objects in each. 3.OA.3- Use multiplication and division within 100 to solve word

problems in situations involving equal groups, arrays and measurement quantities.

3.OA.5- Apply properties of operations as strategies to multiply and divide.

LESSON PLAN OUTLINE

Day 1- Multiplication as Repeated Addition

I will introduce this topic by engaging the students in an interactive lesson using Smart Notebook Software-

During this lesson I will introduce vocabulary needed for the skill being taught.

After the lesson, I will show them this video reinforcing the lesson of the day.

After this video students will complete a task from their

textbooks which will allow me to see who has the understanding and who needs further instruction.

Day 2- Arrays and Multiplication

I will introduce this days lesson by showing a video that discusses how to use arrays to model a multiplication problem.

After the video, I will give counters to students, and ask them to create arrays and find the products of given multiplication facts.

Next students will get netbooks and practice their skills by playing a game called space arrays. Before they play they will watch a screencast I made showing the directions.

progress and assisting those who need help.

Day 3- The Commutative Property Of Multiplication

To introduce todays lesson, I will show them a video that I made on a site called go-animate.

http://jeremyaic.weebly.com/day-3.html I will then discuss the features and the key vocabulary from

the video. And give an engaging discussion to launch the lesson.

Students will then create an array for a multiplication fact, and show the commutative property by flipping the array and creating a turnaround fact!

I will assess their understanding while they perform a task in their textbook to make sure they grasp the concept.

Day 4 and 5- Creating Multiplication Word Problems To begin the lesson I will show them a video from https://www.pearsonsuccessnet.com/snpapp/login/login.jsp I will reinforce the vocabulary that is required to make up a

multiplication story. For example, a multiplication story must have a number of groups with a number in each group.

To practice I will give the students a multiplication number sentence on the board. On their slate they will create a number story, and then solve it.

Once comfortable I will let students pick their favorite multiplication fact and write a number story/word problem for that fact. I will then check it when they are done for accuracy.

They will save this problem for an activity they will do on day 5.

Day 4 and 5- Creating Multiplication Word Problems Day 5- Students will use their multiplication problems to create an

illustration for it using a website called- http://www.toondoo.com I will teach the students how to use this website, and they will

be given time to type their problem and illustrate it. When they are finished they will print out their toon. When the students come back from the class, we will present

each others and the other students will be able to solve them! This will conclude my set of lessons that introduces the

meaning of multiplication.

Assessment We will participate in making a bar graph using excel

showing our favorite ways of solving multiplication. I will give a formal assessment on the five lessons to check

for student understanding.
