What is Guess, Check and Revise? Guess and Check" is a problem-solving strategy that students can use to solve mathematical problems by guessing the answer and then checking that the guess fits the conditions of the problem.
Guess, Check, and Revise(steps) • Understand the problem • Make a Plan • Carry out the plan • Check the answer
Problem 1 • The theater club at school put on a play. For one performance, the club sold 133 tickets and raised $471. • Tickets cost $4 for adults and $3 for students. How many student tickets and how many adult tickets did the club sell? • Step 1 (understand the problem): • Ticket cost = adult $4, student $3 • Number of tickets sold: 133 tickets • Money raised=$471
Step 2 (make a plan): • We are going to take a guess, and then test it. If not correct, then we use what we learned to make a better guess. • To find how much money was made on adult tickets, multiply your number by 4.
On your own: • IXL 5th grade: J3
