Drawing
Y= 3
Considerations: This lesson represents a skill necessary for mastery of 1.OA.1. Missing addends can be represented by any letter or symbol.
Steps: 1. Identify the unknown. 2. Use a drawing to solve for the unknown. 3. Record the unknown.
Missing addend in the second position:

1.
State the objective: Today, I will solve equations with unknowns in the first and second position.
Explain that the first step is to identify the unknown as X.
Emphasize the next step is to solve for X.
Model how to start at 3, the known addend, and count on using counters until 8 is reached (3…4, 5, 6, 7, 8).
Explain that the 5 counters represent the unknown.
Record X = 5.
☐ + 4 = 10
2.
Restate the objective: Today, I will solve equations with unknowns in the first and second position.
Explain that the first step is to identify the unknown as ☐ .
Emphasize the next step is to solve for ☐ .
Model how to start at 4, the known addend, and count on using drawings until 10 is reached (4…5, 6, 7, 8, 9 , 10).
