Big Ideas: The same strategies for whole number operations can be applied to decimals. We must convert measurements into same-sized units to combine or take away from. In this task students will apply their understanding of decimal operations to a real-life situation. The strategies they have used to compute whole numbers can be applied when working with decimals. Students continue to build understanding of decimals as an extension of whole numbers, just like fractions. In this task, students also work with converting measurements in order to come up with a solution. Vocabulary: add, subtract, multiply, divide, gram, kilogram, milligram Special Materials: Decimal grids Whiteboards Base Ten Blocks
