1. Topic-
 Prime and Composite Numbers
2. Content-
 Factors Prime Composite Arrays
3. Goals: Aims/Outcomes-
 1. Students will create arrays to determine factors of given numbers 2. Students will determine the number of factors for a given number 3.Students will identify numbers as prime or composite
4. Objectives-
 1.Students will manipulate counters into various arrays accurately 2.Students will list facts for given numbers 3.Students will determine whether a number is prime or composite based on its factors
5. Materials and Aids-
 teacher-created worksheet Smartboard notebook lesson chips/counters
6. Procedures/Methods-

A. Introduction-

 1.Teacher will assess prior knowledge of arrays and factors from 3rd grade 2.Teacher will have an array created on the table and ask for the corresponding multiplication fact 3.Teacher will ask students to create a different array with the same number of counters introduce multiple factors

B. Development-

 1.Teacher will use the smartboard lesson to introduce the concept of prime and composite numbers 2.Students will be active participants by popping the balloon to expose factors 3.Students will match the vocabulary word to the correct definition to set vocabulary for the lesson

C. Practice-

 1.Students will create arrays for the numbers 6, 7, 8,and 9 using draggable counters on the smartboard 2.Students will record the multiplication facts and identify the factors for these numbers 3.Students will determine if a number is prime or composite and tap the word to gain immediate feedback

D. Independent Practice-

 1.students will work with a partner to use the strategies practiced to determine if a number is prime or composite 2.students will work with counters and record information on worksheet 3.students will each select two numbers to drop into the vortex page of Smart Notebook lesson to check for individual understanding

E. Accommodations (Differentiated Instruction)-

 1. hands on manipulatives and student choice in answering questions in Smartboard lesson 2.working with numbers less than 30 in number generator 3.Think-Pair-Share opportunities for discussion and reinforcement

F. Checking for understanding-

 1.Teacher will assess student understanding of vocabulary throughout the lesson 2.teacher will assess understanding of concept through observation of manipulative use and Smartboard interactive answers

G. Closure-

 1.Students will create an exit card by grabbing a random number of counters and determining whether it is a prime or composite number 2.Students will write an explanation supporting their choice
