The work of this lesson connects to previous lessons in which students solved Compare, Difference Unknown story problems in a way that makes sense to them. The context is data to revisit previous work in Grade 1 and encourage students to consider more abstract contexts. Students write an equation to match the problem and put a box around the answer to the question, building on their work in previous sections. Students consider addition and subtraction equations that relate to a given problem. When students connect the quantities in the story problem to an equation, they reason abstractly and quantitatively (MP2).
- Solve Compare, Difference Unknown story problems through a data context.
