This week in math, first graders have been working with both nonstandard and standard units as we begin learning about linear measurements. Working with nonstandard units, such as paperclips, students have measured various classroom objects. They are comparing quantities determining which items are longer, shorter, taller, higher, or wider than others. Students have made comparisons between nonstandard and standard units, as well as comparisons among different standard units such as inches and centimeters. As we continue learning about linear measurement, first graders will use a variety of tools including rulers, tape measures, and yard sticks. They will practice accurate measurement, compare units, recognize and use abbreviations, and make estimations.
