Overview & Purpose
Assess your student’s or child’s ability to use subtraction to find the number of elapsed minutes with this quick two-question exit slip.
ON GRADE LEVEL: Grades 2-3
ENRICHMENT: Grades K-1
RETEACH: Grades 4-5
2.MD.3.7 ~ Tell and write time from analog and digital clocks to the nearest five minutes, using a.m. and p.m.
3.MD.1.1 ~ Tell and write time to the nearest minute and measure time intervals in minutes. Solve word problems involving addition and subtraction of time intervals in minutes, e.g., by representing the problem on a number line diagram.
The student/child can use subtraction to find the number of elapsed minutes.
No text needed, however, this lesson goes along with the Go Math! Planning Guide ~ Getting Ready for Grade 3, Lesson 15.
Materials Needed ~ Everything is provided for you:
Exit Slip (make the copies you need)
Student Work Space Sheet
Student Evidence of Learning/Verification
Check your student’s or child’s understanding by the performance on the exit slip.
1. Teach or show your student or child how to use subtraction to find the number of elapsed minutes.
e.g., Batting practice starts at 9:45 a.m. Saturday morning. It ends at 10:10 a.m. How long does batting practice last?
2. Have your student or child complete the exit slip.
3. Assess how well he or she did using the answer key (provided).
Common Error: If there are any missed questions your student or child may not understand how to use subtract to find elapsed time in minutes.
4. Reteach: Draw out two clocks with the times on them and have him or her correct any missed questions using the student work space sheet to explain how they came up with the correct answer.
