This week in 7th grade math we have begun our fourth unit on factors, fractions, and exponents. We started the week by working on divisibility and learning the divisibility rules for 1, 2, 3, 4, 5, 6, 9, and 10. Tomorrow, we will learn about what exponents are and how to do order of operations with exponents in them. We will also learn about the Sieve of Eratoshenes, which is basically a way to identify all the prime numbers. (I will give extra credit on quizzes and tests for knowing the prime numbers 1-100.) On Thursday, we will go over prime factorization and apply it to finding the Greatest Common Factor (GCF) of numbers and sets of numbers with variables and exponents. Friday, we will work on simplifying fractions and fractions with exponents and variables in them. This week I will also be introducing the ruler project that we will be working on this month.
Upcoming assignment:
