<p> 21st Century Learning Design</p><p>Designed by: Saifulnizan Che Ismail</p><p>Prime Number Explorations</p><p>Students will read an informational text lesson, defining prime numbers and explaining how to identify them, as you guide their practice with engaging activities and discussions. Make learning stick with a fun game and quiz to test understanding.</p><p>Learning Outcomes and Objectives:</p><p>Tools used: After this lesson, students will be able to:  Sway  Form  100’s Table   Excel and words Define prime and composite numbers in fun  Deck of playing cards learning using words online.  Skype classroom</p><p> Identify and create formula prime numbers Technology Required: using excel. PC with internet access </p><p> Collaboration and explore the prime number Subjects covered: online using skype classroom. Mathematics & ICT</p><p>Age Range: 12</p><p>Time Required: 3 days</p><p>Page 1 Process</p><p>Lesson 1: Teacher prep: in this lesson students will learn to how to calculate and identify the prime numbers, evaluate the information they find on the internet, create the formula to identify the prime numbers and to evaluate their peers’ work by commenting on it. </p><p>Ask students to create identify the prime numbers using Microsoft words. </p><p>Before the lesson students collect the information about the prime numbers in the website. </p><p>Essential question: What is the prime numbers?</p><p>1. Organize the class into small groups of 4 students. </p><p>2. Students discuss and list the prime numbers (1-100). SKILL: 3. Ask students to decide and color the prime number (1-100) using  Collaboration, Microsoft words online. Pair works activity.  Use of ICT for learning,  Self-regulation,  Skilled Communication,  Knowledge Construction</p><p>Instructions:</p><p>1. The first pupils highlight one number (prime number) in the table using digital ink.</p><p>Page 2 2. Next, the second pupils find and highlight one number of prime numbers in the table. Repeat this step until no more prime numbers in the table.</p><p>3. The pupil who got and found the most numbers of prime numbers is the winner. </p><p>Process</p><p>Lesson 2: Teacher prep: in this lesson students will learn to explore and create formula to identify the prime numbers. SKILL:  Collaboration, Ask students to make two columns in Excel and key in the numbers that they  Use of ICT for learning, want to check.  Self-regulation, 1. Organize the class into small groups of 4 students.  Skilled Communication,  Knowledge Construction 2. Students discuss the formula to identify prime number using excel.</p><p>3. Ask students to key in any numbers 1-100 to explore the prime number.</p><p>The following formula can help students identify the number whether it is a prime number or not, please do as this:</p><p>1. Enter the following formula into a blank cell – C2 for example beside your data:</p><p>=IF(B3=2,"Prime",IF(AND(MOD(B3,ROW(INDIRECT("2:"&ROUNDUP(SQRT(B3),0))))<>0),"Prime","Not Prime")) (B3 is the cell contains the number that you want to check), and then press Ctrl + Shift + Enter keys together, and you will get the result, if the number is prime, it will display “Prime” in the cell, if not, “Not Prime” will be displayed, see screenshot:</p><p>Page 3 Process</p><p>SKILL:  Collaboration,  Use of ICT for learning,  Skilled Communication, </p><p>Lesson 3: </p><p>Teacher prep: in this lesson students will collaborate and explore the prime number using skype classroom</p><p>Activity 1:</p><p> Collaboration between two 2 classes in different school.</p><p> Students play the games Decision Roulette to identify the prime number.</p><p>Page 4 Activity 2:</p><p> Shuffle the cards and deal them face down to the players and ask the players to arrange their in a pile. </p><p> Each round consists of all the players turning over the first card in their pack in an outward motion, giving every player a fair chance of seeing the card as it's turned over. </p><p> When a prime is played, the first player to call out "prime" takes the card and any others that may be in the stack. If there's a tie, the pile should remain in the center and play should continue. If the number turned over isn't a prime number, leave the cards in the center of the table until a prime number appears and the cards are won.</p><p> After a player wins cards, they must shuffle them into their deck before the game can continue. </p><p> Play until one player has all the cards or set a time limit on the game and stop when time is up. </p><p> The player with the most cards at the end of the game wins.</p><p>Activity 3:</p><p> The students do assessment by using Microsoft form.</p><p>Page 5</p>
