Find the greatest common factor of two whole numbers less than or equal to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express a sum of two whole numbers 1–100 with a common factor as a multiple of a sum of two whole numbers with no common factor. For example, express 36 + 8 as 4 (9 + 2). Apply and extend previous understandings of numbers to the system of rational numbers.

Administering the Quiz

5 minutes

I will seat students in rows alphabetically. Students will be instructed to take out a sharpened pencil and clear their desks of any notebooks or paper.

I will explain to students that this quiz is based on their knowledge of finding the gcf and lcm and applying them to word problems. Not only is it important for them to know the answer, but also to show how they arrived at their answer.

I will give students 30 minutes to finish the quiz. If students finish early, they will be allowed to read a book.
