Introduction

Use a scale or balance to determine weight/mass in both metric units (grams, kilograms) and U.S. customary units (ounces, pounds).
Measure length in metric units (millimeters, centimeters and meters) and U.S. customary units (fractions of an inch, inches, feet, yards).
Measure liquid volume in metric units (milliliters, liters) and U.S. customary units (teaspoons, tablespoons, cups, pints, quarts, gallons).
Measure the perimeter of plane geometric figures such as triangles, quadrilaterals, and irregular shaped polygons.
Draw points, lines, line segments and rays and understand how they are related.
Draw lines that are intersecting, parallel and perpendicular.
Collect data and display in bar graphs with incremental values labeled on the axes. Include a title and a legend.
Determine the approximate probability of a given event using materials. For example, if a bag contains 5 blue marbles and 20 red marbles what is the probability of randomly picking a blue marble.
