Read the word problem twice. Determine what’s being asked and what’s unknown.
• What’s being asked: How many Puppy Place books will have been published between 2020 and 2022?
• First unknown: How many books were released between 2020 and today?
Solve for the first unknown.
• The series currently has 61 books.
• 55 books were published before 2020.
61 – 55 = 6 books
So 6 books were published since 2020.
Use your solution to solve for the next unknown.
• 6 books have been published since 2020.
• 3 more books will be released this fall and winter.
6 + 3 = 9 books
So by the end of the year, 9 Puppy Place books will have been published since 2020.
