Lisa buys 32 energy bars for swim meets. She brings 4 bars to each meet. How many meets can Lisa go to before all the bars are gone?
Use a visual model to represent and solve the problem.
Liza can go 8 meets before all the bars have gone.
Turn and Talk How can you write a division equation to model the problem? What does each part of the equation represent?
1. Lisa’s swimming coach has $50 to spend on this pair of goggles. How many pairs of
goggles can the coach buy?
A. For each pair of goggles that the coach buys, what happens to the amount of money that he has to spend?
For each pair of goggles the coach buys, his money that he has to spent gets reduced.
B. Why can you use subtraction to show that process?
I can use the subtraction to show the process as every time i spent money reduces.
C. Show how you can solve using repeated subtraction.
D. How many pairs of goggles can the coach buy? ______________ How do you know? ___________________
E. How much money will the coach have left after he buys all the goggles he can with $50? ___________
F. For 50 ÷ 8, the whole number quotient is ___ and the remainder is ___, or ___ r ____.
D. Coach can buy 6 goggles, i came to know by dividing 50 by 8.
E. The will have $2 leftover after he buys all the goggles he can with $50.
F. For 50 ÷ 8, the whole number quotient is 6 and the remainder is 2.

2. Coach Rivera has 36 nose clips to give to members of her synchronized swimming team. Each swimmer gets 5 clips. How many swimmers are on the team?
A. Write a division equation to model the problem.
B. Use repeated subtraction to divide. Start with the dividend. Subtract the divisor as many times as you can.
C. Count the number of times you subtract the divisor to find the whole-number quotient. Any amount left over is the remainder.
D. There are ___ swimmers on the team.
36 ÷ 5 = 7 and 1 is reminder
There are 7 swimmers on the team.
Turn and Talk Could you subtract multiples of the divisor to divide? Why or why not?
