Let’s understand the idea.
- Count intervals of movement, not endpoints. From 15 to 17 there are two one-minute intervals.
- An analog dial repeats. It needs a story or label to tell a.m. from p.m.
- Explain a mistaken reading using the hand positions, then check it by moving one minute at a time.
Something to notice
Ask the learner to read and set an unfamiliar physical analog clock to the nearest minute, explain each hand and write the digital time. Observe real-clock transfer and independent explanation. These lessons address the clock-reading part of 3.MD.A.1; duration, start/end-time stories and number-line reasoning are separate requirements.
Try it. Change it. Explain it.
Open the lesson to use its pictures and controls. In How it works, connect the picture to the idea. In Play & discover, change the quantities and notice what stays the same. In Your turn, answer questions and use the explanation to check your reasoning.
You can ask for help, draw on the thinking pad, or listen to the question and answer options. Progress distinguishes independent work from work completed with help.
