Fractions Parts of a Set
When we explore what fractions really are, there are two ways
in which we can think of fractions. A fraction can
represent part of one whole thing (example: I had 1 slice of pizza for
lunch. I ate 1/8 of the pizza pie.) A fraction can also
represent part of a set. (example 1/3 of the apples in the box had
worms in them!) See if you can correctly match the fraction with
the part of the set that is shown.

The Ruler Game Practice your skills in reading a ruler in this game. The first thing that you will want to do is to set your increment level. I might recommend starting out this game at 1/4 inch increments first and then set it to 1/8 inch increments later. If you become really good at reading a ruler, try the 1/16th increments!
The Metric Ruler Game Practice your skills in reading a metric ruler in this game. When playing this activity, they will provide you with a length in millimeters. Remember there are 10 millimeters in a centimeter! When determining where the length is on the ruler, always keep in mind that each additional centimeter is an additional 10 millimeters! For example, 72 millimeters would be located just 2 millimeters beyond the 7 centimeter mark on the ruler, because there are 70 millimeters in 7 centimeters.
The Measuring Game This website allows you to work in reading either centimeters or inches. If you're having difficulty determining how long the line is, be sure to click on the magnifier to help you determine where the end of the line is located on the ruler.
The Funbrain Measurement Game This website also gives you practice in reading a ruler. Select the difficulty level and whether you want to measure centimeters or inches.
The Measurement Workshop This is a really cool activity by Mr. Nussbaum! I recommend selecting the "play" mode. Once you do that, you will need to select whether you want whole numbers, whole & half numbers, decimals, or fractions. I recommend working with whole & half numbers first. Then I would try your hand at either fractions or decimals next! If you're having difficulty, please be sure to watch the video. REMEMBER.. if you're using fractions and the measurement is less than 1 whole unit, you will need to type in "0" (zero) before typing in your fraction!
Which Metric Measurement Should You Use? This activity gives you practice in deciding which metric unit of measurement to use when measuring the length or area of various objects.
Measuring Angles with a Protractor Game This game is a great way to practice measuring angles with a protractor. Be sure to click and hold the rotate button on the protractor to align it in the correct position to measure the angle.
