Estimating Solutions Involving the Four Operations
T.I.P.S.
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?
