Measurement

===Students convert between units of measure and use rates and scale factors to solve problems. They compute the perimeter, area, and volume of geometric objects. They investigate how perimeter, area, and volume are affected by changes of scale. The links below will help you to investigate more.===

Animal Weigh-In - [mass/weight] Do you know your kilograms from your pounds? Interactive game.

Area Explorer - [area] Students are shown shapes on a grid after setting the perimeter and asked to calculate areas of the shapes.

**Brainingcamp: Pythagorean Theorem** Learn that the Pythagorean Theorem describes the relationship between the lengths of the sides of a right triangle. Discover visual and algebraic proofs. Apply the Pythagorean Formula to find missing side lengths. Derive the distance formula for points in the coordinate plane. **Evaluation and Annotation**

Calculating Areas - Take an online quiz with five multiple choice questions.

Learning About Measures - [length, mass, volume] Use these links to find length, mass, or capacity measurement activities.

Measure it - [length] Practice using a ruler, in inches and centimeters.

Measuring Angles - [angle] Use the online protractor to answer the questions.

Measuring Around - Take an online quiz with five multiple choice questions on finding circumferences.

Perimeter Explorer - [perimeter/length] You will be shown shapes on a grid after setting the area and then asked to calculate perimeters of the shapes.

Using a Graduated Cylinder - [volume] Reading a scale in L and mL, estimating and converting between units.

Using a Graduated Cylinder - [volume] Reading a scale in mL only, estimating and converting between units.

Using a Platform Scale - [mass/weight] Practice using scales like the one in a doctor's office. Five Gregs will drop on the scale, waiting to be weighed, see how quickly you can weigh them.
