Today, I will draw arrays and write an addition equation to find the total amount represented.
Vocabulary
Teacher Resources
Array: an arrangement of objects in rows and columns example:
x x x
x x x
x x x
x x x
Considerations: In this lesson, students will continue working with arrays using manipulatives and drawings.
Steps: 1. Draw an array with the given number of rows and columns. 2. Write an addition equation to show the total number of manipulatives.
4 + 4 + 4 = 12 Application of MPs: MP2: What does your model represent? MP3: How does your model support your answer? MP7: Where can you see a pattern? MP8: Can you see any repetition in your work?
2. Write an addition equation represented by the array created in the previous problem.
Extension
*MP4: How can you relate this to something in real life?
Create an array and have a partner write the addition equation represented by the array.
Reaching Consensus
*MP3: Do you agree/disagree with what
said?
Student Presentations
*MP6: How do you know your answers are correct/reasonable?
Recap today’s lesson with one or more of the following MP questions: MP2: What did your model represent? MP3: How did your model support your answer? MP7: Where did you see a pattern? MP8: Did you see any repetition in your work?
