Measurement (Ruler)

There are many tools used in math that your kids can learn easily. Some hands on tools include calculators, a compass, a protractor, and a ruler. Set aside another time for them to learn about other basic math tools. Here, we will be focusing on how to use the standard ruler.

A ruler is used to measure units of length, inches, feet and yards. Standard rulers have inches on one side and centimeters on the other. A typical ruler measures up to 12 inches, and is equivalent to 30.48 centimeters. This is also equivalent to 1 foot. Each inch on a ruler has markings in between that are a fraction of an inch. However, you should teach them how to measure a fraction of an inch at another time. You must first have your child understand the basic measurements of inches and centimeters.

Here is an example of what a standard ruler looks like:

(Top ruler is in inches, the bottom ruler is in centimeters. 1 inch = 2.54 centimeters)

Learning how to use the standard ruler is a very simple concept to master. Have your child measure simple items lying around the house so that they can feel comfortable measuring in inches and centimeters before advancing to other standards of the metric system such as feet and yards.
