This Problem Set is a part of the Lesson 1, Unit 7, Grade 2. In this lesson, students categorize animals into classes (mammals, birds, fish, and reptiles), organize them in the form of a table, and then use the category counts to solve simple "put together," "take apart," and "compare" word problems. They record category counts in the tables with both numerals and tally marks.
