12 practice questions · Optional read aloud · Thinking pad

Let’s understand the idea.

  1. Close to the next number does not mean the next hour has arrived.
  2. At 2:59 the short hand has almost reached 3. One minute later it reaches 3 and the clock reads 3:00.
  3. The dial goes from 11 to 12 to 1. Move one minute earlier and later to explore each boundary.

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.
