Mrs. Heflin picked 287 strawberries. If she can only put a maximum of 8 strawberries into each basket, how many baskets will she need to hold all of her strawberries?
Students should divide 287 by 8. This will give them 35 with a remainder of 8. Many students will answer 35, but the actual answer is that she will need 36 baskets to hold all of her strawberries. Interpreting remainders is an area of concern for many students.
Find the slope of the line passing through the points (-1, -1) and (2 , 2).
m = (y2 - y1) / (x2 - x1) = (2 - (-1)) / (2 - (-1)) = 1
