The student will solve single-step and multistep practical problems involving addition, subtraction, multiplication, and division of decimals.
construct circle graphs;
draw conclusions and make predictions, using circle graphs; and
compare and contrast graphs that present information from the same data set.
describe mean as balance point; and
