Purpose and Instructional Strategies
The purpose of this benchmark is for students to tell time to the nearest minute, using a.m. and p.m. appropriately. In Grade 2, students tell and write time on analog and digital clocks to the nearest five minutes, including using language that expressions fractional parts of an hour (e.g., “half of,” “half past,” “quarter of,” “quarter after,” and “quarter til”). Students also bring understanding about a.m. and p.m. from Grade 2, and they also related partitioned circles to number lines with the purpose of helping them count by 5s.- Instruction should connect how students can count by fives and ones to identify the exact time on an analog clock. For example, if the time on an analog clock shows 3:19, students should know that they can use the minute hand to count by 5s to land at the 3 on the clock (15 minutes after the hour), and then count ahead 4 more minutes to represent 19 minutes. Students could also count by 5s to get to the 4 on the clock (20 minutes after the hour), and then count back one to get to 3:19. During instruction, allowing students opportunities to use flexible strategies for telling time will build understanding and continue to connect telling time to using number lines (MTR.4.1, MTR.5.1).
- Manipulatives that help students tell and write time are Judy clocks, virtual clocks, and number lines (that can be folded as a circle around a clock and unfolded to show a linear representation) (MTR.2.1). It is important to note that when using number lines during instruction, students should be given the opportunities to determine the intervals and size of jumps on their number line. This approach also connects to measuring lengths (MA.3.M.1.1).
Common Misconceptions or Errors
- Students can misrepresent the location of the hour hand when expressing a given time on an analog clock. For example, when representing the hour hand for 3:19, students can be unsure where the hour hand is located between the 3 and 4. Model reasoning with students that the hour hand should be less than half way between 3 and 4 because 3:19 is before 3:30 when the hour hand would be in the middle. Allow for classroom discussions that encourage students to justify the location of hour hands between benchmarks when representing analog time.
Strategies to Support Tiered Instruction
- Instruction includes classroom discussions that encourage students to justify the location of hour hands between benchmarks when representing analog time.
- Instruction includes how the hour hand moves around the clock. Instruction includes using a one-handed (hour hand only) clock. As students receive given times from the teacher, they should reason the location of the hour hand for that given time.
- For example, the teacher models where the hour hand of the clock should be if the time is 2:37, reasoning for the students so they understand that they should point the hour hand slightly more than halfway between the 2 and the 3 on the clock because 2:37 is just past 2:30.
- Instruction includes understanding that the hour hand moves around the clock. Instruction includes using a geared manipulative clock. This clock will demonstrate the relationship between the minute hand and hour hand moving around the clock.
- For example, the teacher moves the hands on the clock so the hour hand is slightly more than half-way between the 2 and the 3 asking, “What time do you think it is on the clock?” (The clock reads approximately 2:37.) The teacher allows for classroom discussions that encourage students to justify the location of hour hands between benchmarks when representing analog time.

STEM Lessons - Model Eliciting Activity
In this Model Eliciting Activity, MEA, students will help the Sweet Donut Shop determine what the newest donut will be. Students are given the cost to make each batch along with the selling price and are asked to determine the profit for each batch. Students create a procedure for ranking the donuts and write a letter explaining the procedure and the ranking. In the “twist” students are provided the starting and finishing times for each batch. They must determine the total amount of time, decide if their procedure should change based on the new information, and write a letter explaining whether the procedure changed and the new ranking of the donuts.
Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem, while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought process. MEAs follow a problem-based, student centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator.
