In a previous section, students composed and decomposed numbers up to 9. In this lesson, students first act out a Put Together, Total Unknown story problem, which was introduced in the previous lesson. Then students are introduced to a questionless Put Together/Take Apart, Both Addends Unknown story problem. Red and yellow apples are used as a context so that students can easily represent the story problems with two-color counters (MP2). In the next lesson, students will solve a Put Together/Take Apart, Both Addends Unknown story problem.
