EngageNY5 min(s)

This Instructional Activity is a part of the Lesson 19, Unit 4, Grade 6. Students develop expressions involving addition and subtraction from real-world problems. It should be clear that the day I was born was my sister's second birthday. Since my sister's age is always two years more than my age, we just add two to my age.
