Grade 1 Unit 3 Lesson 8 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 7 + 2 =.
Use the strategy ‘count on’ to find the sum.
Section 2:
Write the equation 6 + 4 =.
Use the number line to find the sum.
Section 3:
Write the equation 8 + 5 =.
Use a tens frame to find the sum.
Section 4:
Write the equation 8 + 3 =.
Find the sum using one of the previous strategies.
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?
Tell me how your group proved the addition problems.
What strategies were the easiest to use?
What other way could you have found the sums?
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?
