Problem of the Day Thad sees 7 beetles when he weeds his garden. Each beetle has 6 legs. How many legs are there on all 7 beetles? On your personal white board, draw and label a tape diagram to model this problem. Use the letter b for the beetles’ legs to represent the unknown. 7 x 6 = b, b = 42.

PROBLEM SET – GET IN A GROUP OF 4 – 6 and I will assign each group a problem. Model the problem with a drawing. Write an equation using a letter to represent the unknown fact. Solve for the unknown. Each group will share their solution with the class.

Problem A. Each student gets 3 pencils. There are a total of 21 pencils. How many students are there?

PROBLEM B Henry spends 24 minutes practicing 6 different basketball drills. He spends the same amount of time on each drill. How much time does Henry spend on each drill?

Problem C Jessica has 8 pieces of yarn for a project. Each piece of yarn is 6 centimeters long. What is the total length of the yarn?

PROBLEM D Ginny measures 6 milliliters of water into each beaker. She pours a total of 54 milliliters. How many beakers does Ginny use?
