MC & MP Check
Are students able to collaborate in a small group?
Does the students work show an understanding of making a ten?
Does the students work show an understanding of creating equivalent but easier and known sums?
Does the students work show an understanding of using multiple strategies to find a sum?
Are students able to articulate what they would do differently to solve the problem? (Error Analysis)

Grade 1 Unit 3 Lesson 16 T TE
Verbal Instruction *MP1: Make sense of the problem and persevere in solving it! *MP8: Find a strategy to help solve the problem.
Section 1:
Write the equation 9 + 8 =.
Make an easier and known sum to solve.
Section 2:
Write the equation 9 + 8 =.
Solve this problem a different way by creating an equivalent but easier and known sum.
Section 3:
Write the equation 6 + 7 =.
Make an easier and known sum to solve.
Section 4:
Write the equation 6 + 7 =.
Solve this problem a different way by creating an equivalent but easier and known sum.
Group Presentation *MP3: Do you agree/disagree with what
said?
*MP6: How do you know your answers are correct/reasonable?
Sample Probing Questions:
For section 4, what strategy did you use? Why?
Tell me how your group proved the addition problems.
What strategies were the easiest to use?
Reflective Closure
Were we able to work together as a group?
Were most groups able to complete the tasks?
Were we able to verbalize our mathematical content and practice?
