Let’s learn about measuring things! When we talk about length, we mean how long something is. Width is how wide it is, and height is how tall it is. We can measure these using different methods.
One fun way to measure is by using objects like paper clips. This is called using non-standard units. To measure with paper clips, line them up next to the object you want to measure. For example, if you have a pencil, you might find it’s four paper clips long. A picture frame might be three paper clips tall and two paper clips wide.
You can use other objects too, like your hands or building blocks. Just make sure all the objects you use are the same size. You could see how many hands wide your desk is or how many blocks tall a water bottle is!
We also have standard units of measurement. These are always the same size. For example, a paper clip is about one inch long. A storybook might be about a foot long, and a window could be about a yard wide. Remember, there are 12 inches in a foot and three feet in a yard.
In the metric system, a paper clip is about one centimeter wide. One inch is about two and a half centimeters, and a bookshelf might be about a meter high. There are 100 centimeters in a meter.
We use tools like rulers, yardsticks, and metersticks to measure. To get the right measurement, make sure the end of the ruler is lined up with the edge of the object. If it’s not lined up correctly, the measurement won’t be accurate.
For example, if you measure a box and the ruler isn’t lined up right, you might think it’s four inches when it’s really three inches. Always check that the edges match up!
Before measuring, you can estimate how long, wide, or tall something is. Estimating helps you decide what kind of measurement to use.
Let’s try estimating and measuring some objects:
Remember, always line up the edges of the objects with the measuring tools to get the correct measurement!
Measure Your World: Choose three objects in your home, like a book, a toy, and a shoe. Use paper clips or another non-standard unit to measure their length, width, and height. Write down your findings and compare them with a friend or family member. Discuss why some objects might be longer or taller than others.
Estimation Game: Before measuring, try to estimate the length, width, or height of different objects around you. For example, estimate how many paper clips long your pencil is or how many hands wide your desk is. After estimating, measure the objects using a ruler or paper clips to see how close your estimates were. Talk about why estimating is useful and how it helps us in everyday life.
Create a Measurement Journal: Start a journal where you record the measurements of different objects you encounter each day. Use both non-standard and standard units. Draw pictures of the objects and label their measurements. Over time, see if you notice any patterns or if your estimation skills improve!

**Measurement: Length, Width, and Height**
Length is how long an object is, width is how wide it is, and height is how tall it is. We can measure with a group of objects, such as paper clips, as long as they are all the same size. This is called non-standard units of measurement.
To measure with paper clips, we line them up alongside an object to see how many paper clips long, wide, or tall it is. For example, the pencil is four paper clips long, the height of the picture frame is about three paper clips, and the width of the frame is about two paper clips.
When using non-standard units of measurement, we can use many different objects. For instance, we can put our hands side by side across our desk to see how many hands wide it is, or stack building blocks to see how many blocks tall a water bottle is. Other objects we can use include erasers, pieces of paper, and more. The important thing to remember is that whatever group of objects you are using, they must all be the same size.
We also measure with standard units. These are set units of measurement that are always the same size. For example, a paperclip is about one inch long, a storybook is about a foot long (there are 12 inches in one foot), and a window is about one yard wide (there are three feet in one yard and 36 inches in one yard).
We can also measure with metric units. A paperclip is about one centimeter wide, one inch is about two and a half centimeters, and a bookshelf is about a meter high (there are 100 centimeters in one meter). We can use a ruler, yardstick, or meterstick to measure the length, width, and height of an object.
To measure, make sure that the end of the ruler is lined up with the edge of the object. If the placement is incorrect, we will not get the true measurement. Placement is very important when measuring.
For example, this is not the correct way to measure the box; the edge of the block is not lined up with the end of the ruler, resulting in a measurement of about four inches. This is the correct way to measure the block; the edge is lined up with the end of the ruler, giving a true measurement of about three inches.
We can estimate how long, wide, or high something is before we measure, which helps us know what type of measurement to use.
Let’s take a look at some objects, estimate their measurements, and then take actual measurements.
For the width of a nickel, I estimate about three centimeters. The actual width is two centimeters.
For the length of a crayon, I estimate about five inches. The actual length is about four inches.
For the height of a bucket, I estimate that it is about one foot. The actual height is about one foot or 12 inches.
For the width of a door, I estimate it is one yard or one meter wide. The actual width is about one yard or three feet or 36 inches.
In all cases, notice that the edges of the objects are lined up with the ends of the measuring tools.
