Students must be able to estimate solutions to real-world problems using the operations of addition, subtraction, multiplication, or division. Students will also need to be able to explain how they estimated the solutions.
Example
Hunter has been saving money to buy a new football. The one that hopes to buy costs $43.24, including sales tax. So far, he has saved $18.75. About how much money does Hunter still need to save in order to have enough to buy that football?
5.3 Number and operations. The student applies mathematical process standards to develop and use strategies and methods for positive rational number computations in order to solve problems with efficiency and accuracy. The student is expected to:
(A) estimate to determine solutions to mathematical and real-world problems involving addition, subtraction, multiplication, or division
