EngageNY 60 min(s)

In this lesson, students use 5-group cards to solve "put together with result unknown" problems based on stories and pictures (for example, "In a first-grade classroom, 5 students are sitting down and 2 students are standing. How many students are there in all?"). They use pictures and 5-group cards to represent the quantities involved, and count on to find the total. They also represent their thinking with number bonds and expressions.
