## Unit of Study: Measurement
5/2/2016
Common Core State Standards:4.MD.1 Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two column table.4.MD.2 Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement qualities using diagrams such as number line diagrams that feature a measurement style.Essential Vocabulary: Decimal Fraction Units Equivalent Measure Metric Customary Convert/conversion Liquid volume Mass Length Distance Unit Overview:In this unit, students will apply their understanding of measurement to help them convert measurements within a single system: metric or customary for the first time. Units of measure that are introduced for the first time are: cups, pints, quarts, gallons, pounds, ounces, kilometers, millimeters, and seconds. Additional, the students will reinforce their understanding of place value by using their knowledge to convert within the metric system. Strategies/Skills:Students will build on their understanding of fractions from 3rd grade to make sense of decimals when comparing their equivalency. They are expected to use a variety of models to support their reasoning about numbers.

If your child is having problems, please let the classroom teacher know. When helping your child with his/her math homework, you don’t have to know all the answers! Instead, we encourage you to ask probing questions so your child can work through the challenges independently. What is the problem you’re working on? What do the directions say? What do you already know that can help you solve the problem? What have you done so far and where are you stuck? Where can we find help in your notes? Are there manipulatives, pictures, or models that would help? Can you explain what you did in class today? Did your teacher work examples that you could use? Can you go onto another problem & come back to this one later? Can you mark this problem so you can ask the teacher for an explanation tomorrow?
