This math assessment workbook includes problems focused on identifying common and greatest common factors, differentiating between prime and composite numbers, understanding the prime factorization of numbers, and working with factors and multiples. Learners identify common factors of numbers, such as 24 and 40. Then, they need to find the greatest common factor of numbers, such as 45 and 36. Frequent prime versus composite questions reinforce divisibility rules. Converting six-digit numbers from words to numerals strengthens place value skills. Key Common Core skills include finding common and greatest common factors, classifying numbers as prime or composite, and converting between word and standard forms.
