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 |
