Considerations: Math vocabulary and a number line are provided in the student journal.
Steps: Break apart 3 9+3= 9+3= 9+3=
9+1+2 10 + 2 12
Make 10 Equation: number sentence that uses an equal sign to show that two groups are equal
9 + 3 = 12
1. Use the base ten frames to break apart a number and make 10. 2. Record the expression that shows how to break apart a number to make 10. 3. Record the expression that shows 10. 4. Record the sum.
Application of MPs: MP1:
What strategies were used to solve the problem?
MP5: What tool did you use to help solve the problem? MP7: Is there another way to see the problem?
Expression: a number phrase that shows the value of something (has no equal sign) 9+3
/ *MP1: Make sense of the problem and persevere in solving it! *MP8: Find a strategy to help solve the problem. Directions: Use base ten frames to break apart a number to make 10 and find a sum.
Directions: Use base ten frames to break apart a number to make 10 and find a sum.
9+4=
1.
9+4= 9+4= 9+4=
8+3=
2.
8+3= 8+3= 8+3=
*MP3: Do you agree/disagree with what
said?
*MP6: How do you know your answers are correct/reasonable?
Recap today’s lesson with one or more of the following MP questions: MP1: What strategies were used to solve the problem? MP5: What tool did you use to help solve the problem? MP7: Was there another way to see the problem?
