Telling Time Study Guide

Key Concepts:

• Analogue Clock: A clock with hands that move around a circular face to show the time. It typically has an hour hand (shorter) and a minute hand (longer).
• Digital Clock: A clock that shows the time using numbers.
• Hour Hand: The shorter hand on an analogue clock that indicates the hour. It moves more slowly.
• Minute Hand: The longer hand on an analogue clock that indicates the minutes. It moves more quickly.
• Nearest Hour: Identifying the whole hour that the current time is closest to.
• Half Hour: A point in time that is thirty minutes past a whole hour. On an analogue clock, the minute hand points directly to the number 6 at the half hour. The hour hand will be halfway between two hour numbers.
• Teaching Mode (Simulation): A mode within the digital simulation designed to help children understand how the hour hand moves in relation to the minute hand, particularly around the half hour.
• Non-Teaching Mode (Simulation): A mode within the digital simulation that displays the analogue clock in a way that closely resembles real-world clocks.
• Interactive Elements (Simulation): Features within the digital simulation that allow users to manipulate the clock hands or settings, often indicated by cross-hair circles.

Quiz:

1. What is the primary difference between an analogue clock and a digital clock in how they display time?
2. On an analogue clock, which hand is shorter and which is longer? What does each hand represent?
3. Explain what it means for the time to be to the "nearest hour." Provide an example.
4. Describe the position of the minute hand on an analogue clock when it is half past an hour. What about the hour hand?
5. What is the main purpose of the "teaching mode" in the described time-telling simulation?
6. How does the "non-teaching mode" of the simulation differ from the teaching mode?
7. What visual cues in the simulation allow users to interact with the clock hands?
8. Why might some children mistakenly read a time like 6:55 as 7:55 on an analogue clock? How does the simulation address this?
9. What does the hint "words show" in the simulation aim to help children understand? Give an example of such a word hint.
10. According to the text, for what age range is the simplified view of the clock in the teaching simulation primarily intended?

Answer Key:

1. An analogue clock uses moving hands on a circular face to display time, while a digital clock uses numerical digits to show the hour and minutes.
2. The shorter hand is the hour hand, indicating the hour, and the longer hand is the minute hand, indicating the minutes.
3. Telling time to the nearest hour means identifying the whole hour that is closest to the current time. For example, if the time is 3:50, the nearest hour is 4 o'clock.
4. When it is half past an hour, the minute hand on an analogue clock points directly to the number 6. The hour hand will be halfway between the number of the hour that has just passed and the next hour.
5. The main purpose of the "teaching mode" is to help children understand the movement of the hour hand in relation to the minute hand, especially as it approaches the next hour around the half-hour mark, clarifying that 6:55 is still in the 6 o'clock hour.
6. The "non-teaching mode" displays the analogue clock in a way that is similar to how real analogue clocks typically look, without the specific emphasis on the hour hand's subtle movements seen in the teaching mode.
7. Interactive elements in the simulation are shown as cross-hair circles on the hour, minute, and sometimes second hands, allowing users to click and drag to adjust the time.
8. Children might mistakenly read 6:55 as 7:55 because the hour hand is very close to the number 7 at that time. The simulation addresses this by visually showing the relationship between the minute and hour hand positions more explicitly in the teaching mode.
9. The hint "words show" is designed to help children understand the common English phrases used for telling time, such as "half past" to represent thirty minutes past the hour.
10. The simplified view of the clock with the hidden seconds hand in the teaching simulation is primarily intended for children aged 6 to 9 years old.

Essay Format Questions:

1. Discuss the pedagogical benefits of using a digital simulation, like the one described in the sources, for teaching children how to tell time on analogue and digital clocks to the nearest hour and half hour. Consider the advantages of interactive elements and different display modes.
2. Compare and contrast the information conveyed by an analogue clock and a digital clock. In the context of learning to tell time, why might it be beneficial for students to understand both formats?
3. The sources highlight specific learning difficulties children may encounter when learning to tell time on an analogue clock, such as misinterpreting the hour hand's position near the half hour. Explain how the described simulation attempts to address these challenges.
4. Analyze the potential role of open educational resources, such as the JavaScript HTML5 applet described, in making learning materials more accessible and adaptable for educators and learners.
5. Based on the description of the simulation's features (teaching mode, non-teaching mode, interactive elements, hints), outline a lesson plan or activity that a teacher could use to effectively teach students how to tell time to the nearest hour and half hour using this tool.

Sample Learning Goals

[text]

For Teachers

Introduction
The teaching simulation starts running immediately, showing the real world time. The seconds (RED) hand is hidden by default to make the view simple for children age 6 to 9 years old. The view is simple, with just the hour ( BLUE) and minute (MAGENTA or easier to call it PINK?) hands. The interactive elements are shown as cross-hair circles on the hour, minute and second hands that automatically compute the respective positions.
The teaching mode is created to help children realize 6H55M is actually 6H55M and not 7H55M as the hour hand really points very closely to 7 for example.
The non teaching mode is also available which shows the analogue display in most real clocks.
The simulation works best and need to be paused for user inputs via the drop-down menu to select various show/hide properties
The hints 'words show' is also designed to help children realized the logic of the English language such as 'half past hour'.
Some children may drag to 2H10M position on the clock face, thinking that it is 2H, so you need to watch out for that and address that learning difficulty.
Reset the simulation will put it back to its original set.
Enjoy!
Rate the app and share what you think will help children learn. I will try to add new features if time permits :)
