We are starting our unit of study on Number Theory this month. Number Theory forms the second half of our study of Discrete Mathematics, which is the material of the Option topic in Math HL, which comprise the topics of Paper 3 of your Math External Assessment this May.
Tuesday, 1/2 - we learned about the pigeonhole principle, which is a method of mathematical proof. Here are the slides from class.
Wednesday, 1/3 - we learned about divisibility of numbers. Here are the slides from class. Here is your HW worksheet - try 3 or 4 problems or a half hour of work, whichever comes first.
Thursday, 1/4 - SNOW DAY!
Friday, 1/5 - it's Alumni Day and you have your senior potluck breakfast and other activities throughout the day. We did not meet as a class.
Monday, 1/8 - we learned about the division algorithm for numbers. Here are the slides from class. Here is your HW worksheet.
Tuesday, 1/9 - we learned about the GCD and the LCM of pairs of numbers. Here are the slides from class.
Wednesday, 1/10 - we learned about the Euclidean algorithm for finding the GCD of two numbers. Here are the slides from class. Your HW is p. 25 (Ex. 2C) #1e, 2e, 3, 4, 5.
Thursday, 1/11 - we learned about prime numbers. Here are the slides from class. Your HW is p. 30 (Ex. 2D) #1abc, 2, 3, (optional challenge 4).
Friday, 1/12 - we learned about different number bases and converted between base ten and other bases and vice versa. Here are the slides from class. Your HW is p. 34 (Ex 3A) #1, #2a(i), c(i), e(i), f(i), 3, 4.
Tuesday, 1/16 - we did arithmetic operations in different bases, without changing to base ten first. Here are the slides from class. Your HW is p. 39 (Ex. 3C) #1ai, 1bi, 2ai, 2bi, 3.
Wednesday, 1/17 - we have a group quiz on the number theory topics we've learned so far. Here are the problems we worked on in class. Here are the solutions to those problems.
Thursday, 1/18 - we practiced for our number theory exam happening tomorrow. Here are the problems we worked on in class. Here are the solutions to those problems.
Friday, 1/19 - we have our last math exam of the semester, on number theory.
