Hello, boys and girls! This is Teacher Mike, and today I’d like to talk to you about different measuring tools. First, we’re going to review what these measuring tools are and how we can use them appropriately. Then, we’re going to look at some objects and choose the correct tool to measure each object. Let’s get started right away!

The first tool I’d like to talk to you about is the ruler. A ruler is 12 inches long and is used to measure smaller objects. When we use the ruler, we want to make sure that the objects we measure are smaller than the ruler so that we can measure them accurately.

The next tool I’d like to discuss is a yardstick or a meter stick. A yardstick is exactly three feet long because there are three feet in one yard. A meter stick is about three feet long as well, so we can use a meter stick and a yardstick in a similar way. We use a meter stick or a yardstick to measure bigger things because they are like having three rulers stacked on top of each other. We use a yardstick for larger items, like a table.

Next, I’d like to talk about a plastic tape measure. A plastic tape measure is really cool because you can use it to measure not just straight objects but also curvy objects, like your hips. A plastic tape measure is a unique measuring tool that can help measure objects that aren’t perfectly shaped.

The last measuring tool I’d like to teach you about is a metal tape measure. A metal tape measure can range from 50 to 200 feet long, meaning you can measure things like houses and cars. A metal tape measure is really useful for measuring things that other tools can’t measure.

Now, let’s read the directions for our worksheet and get started right away! Help Steve measure different things in his house. Check the most suitable tool for each measurement.

Let’s get started! First, we have a nail, and our two choices for measurement are a ruler or a metal tape measure. I remember telling you that a metal tape measure can measure distances between 50 and 200 feet. Is a nail really that big? I don’t think so! In my estimate, a nail is a few inches long, so the best tool to measure a nail is, in fact, a ruler. We would only need one ruler to measure a nail, which makes this the right choice.

The next object we want to look at is a soccer ball. For this measurement, we want to measure around the soccer ball. To measure a curvy or round object, there’s really only one choice: the plastic tape measure. This will help us measure curvy or imperfect objects. A ruler would not be an appropriate choice for this because there is no straight line to measure on a soccer ball.

Next, we want to measure a door. This door is pretty big, so I don’t think a ruler will be enough because we would need multiple rulers to measure this door. However, if we had one meter stick, we might be able to measure this door. We might need two, but it’s still more appropriate than using a ruler.

Finally, we have a house. How big do you think this house is? Our two choices for the house are the ruler and the metal tape measure. If I were to measure this house using the ruler, I would need a lot of rulers. But if I were to measure using one metal tape measure, I might be able to measure the whole house. So, the metal tape measure is the appropriate choice here because it can measure distances or lengths from 50 to 200 feet long.

Thanks for watching, boys and girls! I hope you learned a little bit about selecting the correct measurement tool. We’ll see you next time!

Hello! I have a new worksheet today. The name of the worksheet is called “Centimeters and Inches.” Most rulers come with both inches and centimeter markings. Use the ruler to measure the picture below and check the correct answer.

So, what we’re going to do is use the yellow ruler to measure different things. Let’s look at our ruler first and get an idea of where everything is. When I look at this ruler, I see that the smaller markings are centimeters, and the larger markings are inches.

Let’s look at the glove. We’re going to start at the end of the ruler and line it up with the end of the ruler. It looks like it’s going to be right on the 10, so I’m going to check the correct answer for 10 centimeters.

Now, let’s move on to the next one. This one says it’s in inches. We’re looking for the larger numbers now. We’ve lined up our glove at the end of the ruler, and it goes to the four, so it’s going to be four inches.

Next, we’re measuring a sock. We’re looking for centimeters again, so we’ve got our sock lined up at the end of the ruler, and it is going to be 15 centimeters.

Our last one is another sock. This time, we’re looking for inches again. We’ve lined up our sock with the end, and it comes to the 5, so it’s going to be 5 inches.

Measuring is so much fun and pretty easy! You just have to check, measure, and see where everything is lined up. Great job today!

Hello, boys and girls! This is Teacher Mike, and today I’d like to talk to you about comparing the lengths of objects in centimeters. We’re going to take two different objects and see which one is longer and how much longer that object is.

To figure out how much longer one object is than another, first, you have to measure both objects. Then, you’ll take the length of the shorter object and subtract it from the length of the longer object.

Let’s look at an example. Let’s say we measured two different nails. The first nail is five centimeters long, and the second nail is three centimeters long. It’s easy to tell that the five-centimeter nail is longer, but how much longer? We can subtract to find out. We always put the bigger number on top and the shorter number below. So, we subtract 5 minus 3, which gives us 2. The difference in length between these two objects is 2 centimeters.

Now, let’s read the directions for our worksheet and get started right away! In each pair of objects, check the longer object and circle the correct difference in length between the two objects.

Let’s look at our first two objects: a paperclip and an eraser. The paperclip is 2 centimeters long, and the eraser is 5 centimeters long. Rearranging these numbers, we put 5 on top and subtract 2 from 5. What is 5 minus 2? It’s 3. So, the difference in lengths is 3 centimeters.

Now, let’s take a look at our next two objects: a marker and a pen. The marker is 8 centimeters long, and the pen is 12 centimeters long. Rearranging these numbers, we put 12 on top and subtract 8. The difference is 4 centimeters, so we know that our pen is 4 centimeters longer than our marker.

Remember, boys and girls, when you want to find the difference in length between two different objects, first measure both objects, then subtract the length of the shorter object from the length of the longer object.

Thanks for watching, boys and girls! We’ll see you next time!

Hello, boys and girls! This is Teacher Mike, and today I’d like to talk to you about estimating measurements. This can be tricky but also fun! You can use references from your own life to make estimates about sizes, which can make estimating easier and more enjoyable.

Let’s go over some good estimates for different sizes. One inch is about the size of a bottle cap. Can you think of other things around you that are about one inch?

A foot is about the size of a hammer. A foot is 12 inches long, so it’s like putting 12 bottle caps next to each other. Can you think of other objects that are about the length of one foot?

A yard is three feet long. A good estimate for a yard is about the width of a door.

Now, let’s use these estimates to help us answer the questions below.

First, we have a clothespin. Our first answer choice is two feet. Is a clothespin the size of two hammers? No, that’s too big. The next choice is two yards, which is even bigger. Finally, we have two inches. That makes sense for the size of a clothespin, so two inches is the correct estimate.

Next, we want to know the length of a dog. Our first answer choice is two inches, which is too small. Two feet makes more sense, so that is the correct estimate.

Now, let’s estimate the height of a house. Ten yards seems reasonable, while 10 inches is too small. Ten feet is getting closer, but the best estimate for the height of a house is 10 yards.

Finally, let’s estimate the length of a couch. Six feet is a great estimate because when I lay down on a couch, I fit perfectly. Six yards is too long, and six inches is too small.

Remember, boys and girls, when you want to estimate measurements, you can use objects around you to help you make good guesses. Thanks for watching, and we’ll see you next time! Subscribe to our channel to stay updated on new videos, and find links to our apps in the comments below.
