Your next great Lessn starts here.

Time and Length Units – Learn time unit abbreviations – Seconds (sec), Minutes (min), Hours (hr) – Learn length unit abbreviations – Inches (in), Feet (ft), Yards (yd), Miles (mi) – Why do we measure things? – To know how long or short things are – Measuring in daily life – To cook, build, and know the time | This slide introduces first graders to the concept of measurement, focusing on time and length. Start by explaining that just like we shorten words when we talk, we also use shorter forms for measurement units. For time, we use sec for seconds, min for minutes, and hr for hours. For length, we use in for inches, ft for feet, yd for yards, and mi for miles. Emphasize the importance of measuring in everyday life, such as knowing how much time has passed, how much ingredients to use in a recipe, or how tall you are. Engage the students with examples they can relate to, like measuring their height or the length of their classroom.

Learning About Time – Time tells us when events occur – We measure time in seconds, minutes, hours – Like using a stopwatch or a clock – Short forms: sec, min, hr – ‘sec’ for seconds, ‘min’ for minutes, ‘hr’ for hours – Clocks help us see the time – Clocks have numbers and moving hands to show time | This slide introduces the concept of time to first graders. Time is a way to measure when things happen, from seconds to hours. Use examples like the duration of playtime (minutes) or school hours (hours) to make it relatable. Teach them the abbreviations for each unit of time and show them on a clock. Explain that the short forms are quicker ways to write time units. Use a classroom clock to point out the hour, minute, and second hands. Encourage students to practice saying the time with the abbreviations. For example, 3 minutes can be said as ‘3 min’.

Learning About Length – Length: how long or short – Measure with inches, feet, yards – Use a ruler for inches, a yardstick for yards – Short forms: in, ft, yd – ‘in’ for inches, ‘ft’ for feet, ‘yd’ for yards – Practice measuring things – Find objects to measure at home or school | This slide introduces the concept of length and how it is measured. Length can be thought of as the measurement from one end of an object to the other. It’s important to explain that we use different units like inches, feet, and yards depending on the size of the object we’re measuring. The abbreviations ‘in’, ‘ft’, and ‘yd’ are used for convenience in writing and speaking. To make this lesson interactive, encourage students to practice measuring items with a ruler or yardstick and to use the correct abbreviations for each unit. This will help them become familiar with the concept of length and how to measure it accurately.

Learning About Time with Clocks – Clocks have numbers 1 to 12 – Long hand is for minutes – When the long hand moves, minutes pass – Short hand points to hours – The short hand tells us what hour it is – Practice setting the time! – We’ll move the hands to set different times | This slide introduces first graders to the basics of reading time using an analog clock. Emphasize the numbers on the clock face and explain that there are 12 hours in a full circle. Show how the long hand indicates minutes, with each full rotation equaling 60 minutes. Explain that the short hand shows which hour it is. During class, use a toy clock or a drawing on the board to demonstrate setting the time. Allow students to practice with interactive activities, such as setting the clock for specific times like lunchtime or the end of the school day. This hands-on practice will help them understand the movement of the clock hands and how to tell time.

Using a Ruler to Measure – Rulers measure length – A ruler can tell us how long or short an object is. – Marks for inches and feet – Look for the small marks for inches and longer marks for feet. – Practice measuring items – Let’s use a ruler to measure things like pencils or books. – Understand inches and feet – Inches are small units and feet are bigger units on the ruler. | This slide introduces students to the concept of measurement using a ruler. Explain that a ruler is a tool we use to find out how long or short things are. Show them the marks on the ruler that represent inches and feet. Inches are used for shorter measurements, while feet are used for longer ones. Have a variety of items available for the students to measure, such as pencils, books, or pieces of string. This hands-on activity will help them become familiar with using a ruler and understanding the units of measurement. Make sure to walk around the classroom to assist students and answer any questions they may have about measuring with a ruler.

Fun with Abbreviations – Abbreviations: short unit forms – Save time and space with them – Match units to abbreviations – Can you match ‘Foot’ with ‘ft’? – Examples: Hour (hr), Inch (in) – More examples: Minute (min), Foot (ft) | This slide introduces students to the concept of abbreviations, specifically for time and length units. Abbreviations are like shortcuts that help us write and read faster. They are especially useful when we have limited space, like in charts or tables. Engage the students with a matching activity where they connect common units of measurement with their corresponding abbreviations. For example, they will learn that ‘Hour’ is written as ‘hr’ and ‘Inch’ as ‘in’. This interactive approach helps solidify their understanding of abbreviations in a fun and memorable way. Encourage them to think of other units they already know and their abbreviations.

Class Activity: Measuring Time and Length – Activity 1: Clock Setting Game – I’ll say a time, and you’ll set the clock hands to match! – Activity 2: Classroom Measurement Hunt – Use a ruler to measure items I’ve listed and write down their lengths. – Discuss what we learned – Share your findings with the class! – Tell us about the time you set and the items you measured. | This slide outlines two interactive activities for students to learn about measuring time and length. For Activity 1, the teacher will call out different times, and students will practice setting the hands on a clock to match the stated times. This helps them understand the concept of hours and minutes. For Activity 2, students will use rulers to measure various objects in the classroom, which will introduce them to units of length such as inches or centimeters. After completing the activities, students will discuss what they’ve learned about time and length and share their findings with the class. The teacher should prepare a list of objects to measure and ensure that each student has access to a clock and a ruler. The teacher can also prepare a worksheet for recording the measurements.
