Problem Solving<\/strong><\/p>\n

Use Objects
\nAnswer:
\nA pentomino is an arrangement of 5 identical squares in a plane. The squares must be attached to one another edge to edge.
\n\"Envision<\/p>\n

Question.
\nUsing 5 identical square tiles, how can you build 3 more pentominoes that have 3 squares in a row?
\nAnswer:<\/p>\n

Guided Practice<\/strong><\/p>\n

Do you know HOW?<\/strong>
\nQuestion 1.
\nIs the following a pentomino? Explain.
\n\"Envision
\nAnswer:<\/p>\n

Question 2.
\nAre these two pentominoes the same or different? Explain.
\n\"Envision
\nAnswer:<\/p>\n

Do you UNDERSTAND?<\/strong>
\nQuestion 3.
\nIn the example above, how many more pentominoes can you find with 3 in a row?
\nAnswer:<\/p>\n

Question 4.
\nWrite a Problem Write a real-world problem that can be solved by using objects.
\nAnswer:<\/p>\n

Independent Practice<\/strong>
\nIn 5 and 6, tell whether the pentominoes in each pair are related by a reflection or a rotation.
\nQuestion 5.
\n\"Envision
\nAnswer:<\/p>\n

Question 6.
\n\"Envision
\nAnswer:<\/p>\n

In 7 and 8, use objects to help you solve the problem.
\nQuestion 7.
\nHow many pentominoes can you build with 5 in a row?
\nAnswer:<\/p>\n

Question 8.
\nHow many pentominoes can you build with 4 in a row?
\nAnswer:<\/p>\n

Read and Understand<\/strong>
\nWhat am I asked to find?
\nThree more unique pentominoes that have 3 squares in a row
\nTwo pentominoes are the same if they can be matched together by rotating or reflecting.
\n\"Envision<\/p>\n

Plan and Solve
\nI can use objects to build 3 more pentominoes with 3 in a row.
\n\"Envision
\nHere are 3 possible solutions.<\/p>\n

Look Back and Check
\nAll are attached edge to edge.
\nAll can be rotated and reflected. None are repeated.
\nThe 3 pentominoes I’ve made are all unique.<\/p>\n

Question 9.
\nSuppose each square in a pentomino is a table that seats one person on a side. Find a table arrangement (a pentomino) that can seat 12 people.
\n\"Envision
\nAnswer:<\/p>\n

Question 10.

\n\"Envision
\nAnswer:<\/p>\n

Question 11.
\nMaureen is buying a game that is priced at $15. She has a coupon worth $2.50 off the regular price. After Maureen gives the clerk a $20 bill, how much change does she receive?
\nAnswer:<\/p>\n

Question 12.
\nJames and Kurt were paid $176 for landscaping a yard. James worked 9 hours and Kurt worked 13 hours. How much is Kurt’s fair share of the earnings? James’s share?
\nAnswer:<\/p>\n

Question 13.
\nUse objects to build pentominoes with 2 squares in a row. How many of these kinds of pentominoes can be built?
\nAnswer:<\/p>\n

Question 14.
\nMake an organized list. How many different combinations of coins can make $0.42 if one of the coins is a quarter? One possible combination: 1 quarter, 17 pennies.
\nAnswer:<\/p>\n

Question 15.
