This Problem Set is a part of the Lesson 19, Unit 4, Grade 1. In this lesson, students are presented with "put together/take apart with total unknown" and "add to with result unknown" word problems within 20. As they solve, they draw and box the two parts and then include the numeral label within the box, producing tape diagrams. This enables them to quickly identify where a quantity can be found within the drawing.
