DAILY PRACTICE
Solve each problem. Draw the arrays and write equations. Use another sheet of paper if you need to.
1 Rock bands often stack their speakers in an array. One teen band has 24 speakers. They stack them at least 2 high, but no taller than 8 high. What are all the different arrays they can make?
2 One band has 30 speakers. They stack them at least 3 high, but no taller than 6 high. What are all the different arrays they could make?
3 Another band has 48 speakers. They stack them at least 4 high, but no taller than 6 high. What are all the different arrays they can make?
4 One band has fewer than 40 speakers. They stack them in an array exactly 9 high. How many speakers could they have? Explain how you know.
NOTE
Students find arrays for given numbers with restraints.
