​When solving 2-Step problems, we must follow certain rules

• ​Step 1: Understanding the math problem. What do we already know? What are we required to find?

• Step 2: Plan the model. What are the parts? What is the whole?

  Step 3: Carry out the plan of the model and solve.

  Step 4: Check your answer. Work backwards for each part of the equation.

​Model

​There are 26 adults and 19 children at a park. Later, 7 people leave the park.

a. How many people are at the park at first?

b. How many people are at the park now?

​​Step 1: Understanding the math problem. What do we already know? What are we required to find?

• ​26 adults at the park

• ​19 children at the park

• ​7 people leave the park

• ​Want to know how many people start at the park

• ​Want to know how many people are at the park now

​Step 2: Plan the model. What are the parts? What is the whole?

• ​26 adults is a part

• ​19 children is a part

• ​Missing the whole

• ​7 people that left is another part

  • ​this part is different than before

Step 3: Carry out the plan of the model and solve.

Step 4: Check your answer. Work backwards for each part of the equation.​

​Debriefing for step 1

• ​22 children on Bus A

• ​16 children on Bus A

• ​5 more people on Bus B than Bus A

• Want to know how many people are on each bus

Step 2: Plan the model.​

​What are the parts? What are the wholes?

Step 3: Carry out the plan of the model and solve.

Step 4: Check your answer. Work backwards for each part of the equation.​
