3rd grade - measurement

I show how to measure the volume of some drinking cups in milliliters, using a regular measuring cup. We also talk about liters and the relationship between milliliters and liters: 1000 ml equals 1 liter. Lastly we look at some food and persona care products that show the volume (in milliliters) on the label. I encourage you to do the same, and measure the volume of various items at home (or at school) in milliliters! Find more 3rd grade math videos at

In this lesson, I weight various items on a kitchen scale that measures in pounds and ounces. You will see me weighing a box of dominoes, a large container of water, some tomatoes — and even Mathy my mascot! (And he claims he weighs thousands of kilograms... we shall see about that!) The scale needs adjusted so that the red line is at the zero. This is called the TARE. Some scales have a button for this, but mine doesn't; you have to adjust it manually. So, when we weigh the tomatoes, the empty container is the tare and the scale is reset to show zero WITH the empty container. Lastly we look at the labels on some food items that show the weight of the item, and we weigh those. I encourage you to do similar activities at home, weighing various items, including food items that show their weight on the label. Measuring is best learned hands-on!

A lesson on liquid volume for 3rd grade! I show in real life (with colored water, jars, cup, and measuring cup) that a coffee cup indeed measures one cup, and that two cups make a pint, and that two pints make a quart. I'd like to encourage children to do these same "measurements" because when you get hands-on, it helps you learn the measuring units much better!

In this lesson, we deal with the basics of these measurement units: foot, yard, and mile. I measure lines using a ruler that measures in feet and inches. Then we calculate the area & perimeter of a square with 4-yard sides. Next, it's time to figure out which measuring unit fits best the given situation (fill in the blanks!). Next, we do a few easy conversion problems, converting feet into inches, and also feet & inches into inches. Lastly we solve a word problem concerning two children's heights (given in feet and inches). This lesson is meant for 3rd grade, and it matches Math Mammoth materials.

Learn to measure lengths with a ruler to the nearest quarter (one-fourth) inch! A lesson for about 3rd grade (grades 2-4). First we use a special ruler that shows the 1/4, 1/2, and 3/4 inch marks only, and measure some lines. Then we draw lines of specific lengths and find those same marks on the regular ruler among all the other little lines. Measuring things around the house is kind of fun, so I encourage all students to do just that! Check out also my workbook Math Mammoth Measuring 1 at
