It helps us understand the meaning of numbers and allows us to combine numbers using various mathematical operations. In this unit, students will review place value, comparing and using visual models and problem solving, students will apply their knowledge of place value, as well as gain a deeper understanding of fractions, decimal numbers, prime numbers, composite numbers, factors and greatest common factor (GCF), multiples, and the least common multiple (LCM)., 0,,. Objectives: Students will compare and order rational numbers generate equivalent forms of rational numbers identify multipes, common multiples, and the least common multiple of a set of positive integers identify factora, common factors, and the greatest common factos of a set of positive integers classify positive integers as prime or composite write the prime factorization of composite numbers using exponents 0
