Mathematics Growing by Powers of 10 

I. Planning  
Lesson Summary:This lesson will take Grade 5 students through the multiplication of figures by 10. In 45 minutes, the students will have an opportunity to understand the impact of Power 10 on other numbers. 

Classroom and student factors:The class has 30 students. 4 of them are learning English as a second language (White and Hispanic). Most are within the 5^{th} grade level. 2 are one year above the 5^{th} grade level, while one is two years below. 6 students are either one or two years below the grade level in terms of mathematical performance. 

Standard(s):
Number and Operations in Base Ten

Lesson Objective:
Ø Students should describe the impact on numbers’ size after multiplication by power 10 Ø Students should understand and explain the zeros patterns of the product Ø Comprehend place values Ø Carry out multiplications by the number 10 

Anticipation of Common Misconceptions/Challenges:Ø Expression in English Ø Concentration Ø Active participation of all students 

Key Vocabulary:Ø Multiply Ø Product Ø Power 10 
Differentiation:Ø Use of visual aids Ø Use of diagrams


Probing Questions:Ø What is the effect of Power 10 on other numbers? Ø How many zeros result in different circumstances? Ø What are the key aspects of multiplications by power 10? 

Materials:Ø PowerPoint presentations Ø Chalkboards Ø Flipcharts Ø Rod 

II. Instruction  
The 5Es  
ENGAGE (Anticipatory Set)The teacher opens the lesson by activating prior knowledge, linking previous learning, and presenting objective and focus questions. (5 minutes)


Ø Ask questions that touch on previous lessons
Ø Use tangible items to clarify the answers Ø Using illustrations 

EXPLORE (Multiple Means of Engagement)Students collaborate in problemsolving in order to gain a conceptual understanding of the concept. The teacher asks probing questions and provides prompts to groups and individuals as they work to help them move toward mastery of the objective. (20 minutes) 

Ø Group discussions
Ø Partner Learning 

EXPLAIN (Multiple Means of Representation)Students explain/share findings from the EXPLORE activity, and the teacher facilitates class discussion. The teacher models and asks questions using student input to help connect student responses with the big idea of the lesson. Vocabulary and bigidea concepts are formally introduced. (20 minutes) 

Discussion
Multiplication of even and odd single numeral numbers by power 10 Applying power 10 to numbers with two numerals 
Direct Instruction
Ø Repetition Ø Math games Ø Pair work Ø Group work

ELABORATE (Extension)Practice/Application of the big idea to the same or new concept. (10 minutes)


Ø Use PowerPoint to recap the lesson
Ø Use diagrams to explain multiplication concepts 

EVALUATE (Multiple Means of Expression)Formative assessment activity that is aligned to the objective and focus question to close the lesson. (5 minutes)


Ø Assignments to test understanding
Ø Allow students to ask questions 

III. RATIONALE 

RATIONALEThe main instructions that will be used to implement the lesson plan include repetition, Math games, and pair/group work. Repetition involves reviewing different concepts that build onto the current topic. The teacher can use this technique to help students, especially those learning English as a second language, internalize the critical concepts. Going over the formulas learned in past lessons and multiplication strategies that lead to the attainment of the right product allows even the slow learners to understand the basics. It is important that students master the core concepts of the topic before they can gradually move into advanced topics. The technique will also be used during elaboration and evaluation to ensure that the lesson’s objectives are fulfilled. Math games are ideal for making this lesson interesting and captivating for all students. Besides encouraging active participation in the fun activity, it will also enable the students to concentrate through the 45 minutes. Using games will also make it easy for students to remember the learned concepts. In this case, computer games will be ideal due to the large size of the class (Resilient Educator, 2020). Group and pair work is important in ensuring students learn from each other through collaboration. The instructor will give tasks to pairs and groups of students. Each group and pair will present their solutions by taking the rest of the class through the calculation process. Such an approach will encourage competitiveness and critical thinking as students try to solve mathematical problems. In addition, it also encourages the active participation of all students (Solari, Denton, & Haring, 2017). The process of sharing knowledge enhances understanding of the content.

Question
Educators can develop critical thinking and problemsolving skills for their students by asking strategically planned questions during lessons.
Design an original mathematics lesson plan for the K5 grade level of your choice that promotes critical thinking and problemsolving. Using your state’s math standards and the “Class Profile” as resources, design an original lesson using the “COE Lesson Plan Template.”
In the Multiple Means of Expression section, include five questions that align with the lesson objective the teacher can pose to students.
The questions should:
Activate prior knowledge.
Identify potential student misconceptions that could interfere with learning.
Connect concepts, procedures, and applications.
Encourage critical thinking, exploration, and problemsolving.
The Multiple Means of Engagement section includes opportunities for students to consider realworld applications, prior knowledge, and the steps to solve a problem.
Beneath your lesson plan, write a 250word reflection explaining three instructional strategies you included in your lesson. Describe why these strategies were used and how the strategies promote collaboration, communication, critical thinking, and creativity. Bold the name of the strategy.
While APA style format is not required for the body of this assignment, solid academic writing is expected, and intext citations and references should be presented using APA documentation guidelines, which can be found in the APA Style Guide, located in the Student Success Center.
This assignment uses a rubric. Review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion.
