The blue table group has 6 students, and each brought 2 pencils. The purple table group has 6 students, and each student brought in 4 pencils. After they collected the pencils, Mrs. Woods divided them evenly among the students at those two tables . How many pencils did each student get?
6 x 2 = 12 and 6 x 4 = 24
12 + 24 = 36
So, they have 36 pencils all together. But we need to figure out how much EACH student will get. How many students are at both tables? 6 + 6 = 12. Let's divide!
36 ÷ 12 = 3
3 pencils each.
