This week we tackle the final standard in this unit. Although students have already had experience with LCM and GCF, this standard encompases larger numbers and adds the distributive property. Because of the larger numbers, the factoring method previously learned may take too long. I introduce the Cake Method - both upside down and regular! Our learning targets: I can find the greatest common factors of two whole numbers (up to 100). I can find the least common multiple of two whole numbers (less than or equal to 12). I can use the distributive property to express a sum of two whole numbers. Monday - Watch video: http://www.youtube.com/watch?v=GD5jLpSsN00 Using upside down birthday cake to find the greatest common factor (GCF) (4:25) http://www.youtube.com/watch?v=gGLpBe46wIY Using the upside down birthday cake to find the least common multiple (LCM) (2:33) HOMEWORK: Finish task cards from last week - cards 13-16 Tuesday - The students practice LCM and GCF with the computers playing TicTac Toe. Then practice with Climb the Pyramid LCM in class. HOMEWORK - Climb the Pyramid GCF
Wednesday - As a class, we will play I HAVE WHO HAS – LCM and GCF. Everyone figures out the answer on answer sheet. Then students complete the bottom of the answer sheet to solve the riddle. HOMEWORK - Task Cards 1 - 8
Thursday - Watch video while students copy problems at their seat: Factoring with the Birthday Cake Method https://www.youtube.com/watch?v=eetmpeg1Sso (6:46) Students start on task cards 1 – 12. HOMEWORK: Finish Task cards 1 - 12
Friday - Complete word problem sheet with teacher practicing the distributive property. Then take NS.4 quiz.
