Read hours and half-hours; identify pennies and dimes

Learning goal: Tell and write time in hours and half-hours using analog and digital clocks, and identify pennies and dimes by name and value. These are two parts of the Ohio target, so assess them separately. Use a teaching clock and real child-safe supervised coins or reliable labeled images. Mixed-coin purchasing decisions are not required here.

On an analog clock, the shorter hand tracks hours and the longer hand tracks minutes. At an exact hour the minute hand points to 12. If the hour hand points to 4 and the minute hand points to 12, the time is four o’clock, written 4:00. The clock’s number 12 in this position does not mean twelve minutes after four.

At half past an hour, the minute hand points to 6 because thirty minutes is half of a sixty-minute hour. The shorter hour hand has moved halfway toward the next hour. At 1:30 it lies between 1 and 2, not exactly on 1 and not yet on 2. Read the hour that has begun and add thirty minutes.

The pictured clock shows 1:30. The long hand reaches 6; the short hand is halfway from 1 to 2. The digital display below names the same time. Its colon separates hours from minutes. Do not read 1:30 as one hundred thirty, and do not call the time 2:30 just because the hour hand is moving toward 2.

Move between representations. Set a teaching clock to 7:00 and write the digital time, then start with 7:30 and position both hands. Practice many different hours and half-hours, including a clock whose hour hand is near 12, so one memorized hand position does not stand in for understanding.

For coins, a penny has a value of one cent and a dime has a value of ten cents. Identify them by name using features you can check: a penny is usually copper-colored, has a smooth edge and usually shows Abraham Lincoln on the front; a dime is silver-colored, has a ridged edge and is the smallest of the everyday coins. Most dimes show Franklin D. Roosevelt on the front. Coin pictures can change: a federal law signed in January 2021 (the Circulating Collectible Coin Redesign Act of 2020) allows new designs on coins made in 2026 for the country’s 250th birthday. So rely on the color, size and edge as well as the picture. Check these features on actual coins or labeled images. A coin’s size does not tell its value: a smaller coin can have a greater value than a larger coin. A dime’s ten-cent value is ten times a penny’s one-cent value, though this lesson need not introduce formal multiplication language.

Keep coin count distinct from value. One penny and one dime are two coins, but their individual values differ. When asked to name a coin and its value, do not answer only how many circular pictures appear. Other denominations can be encountered in life, but the required identification set in this particular Ohio first-grade statement is pennies and dimes.

Worked example 1: Hour time. The minute hand points to 12 and the hour hand to 9. Say nine o’clock and write 9:00. Both representations name the same time.

Worked example 2: Half-hour time. The minute hand points to 6 and the hour hand lies between 5 and 6. The time is 5:30, because the hour hand has passed 5 and thirty minutes have gone by since five o’clock. The short hand has not reached six o’clock.

Worked example 3: Name versus value. An adult shows a penny and a dime. Identify penny—one cent, dime—ten cents. A single coin can have either value depending on its denomination; “one coin” is not a complete answer to “what is its value?”

Guided practice: Match analog hour and half-hour displays to digital cards, then create the reverse matches by moving both hands. Separately sort pennies and dimes using reliable examples and say each name with its value. Keep objects away from mouths and use larger printed images when needed.

Independent evidence: Read and write several hour and half-hour times, set a teaching clock from a digital time, and identify both a penny and a dime by name and value. Record the two strands separately. Ask for an explanation of the hour hand’s between-number position in one half-hour example.

Feedback: If the child reads the next hour at half past, move the clock slowly from the prior exact hour to show what has elapsed. If the child calls the minute position 6 six minutes, show that the numeral marks five-minute intervals around the full clock while keeping assessment at hours/half-hours. If coin size replaces value knowledge, compare verified denominations and restate their values.
