Unit 3 Overview:
Unit 3 Overview:
In this unit students will apply their knowledge of measurement to solve measurement problems and convert measurements from a larger unit to a smaller unit. Students will increase their knowledge of capacity units to include cups, pints, quarts and gallons. Fourth graders will gain familiarity of length units to include both metric (km, m & cm) and standard (inches, feet & yards) units. Students will begin to convert measurements using visual aids. Students will expand their knowledge of perimeter and area. They will use various problem solving strategies to find the area of rectangular figures. Fourth graders will apply their knowledge of factors and further explore the relationship between multiplication and area.
- Students will understand relative sizes of units within the metric system (mm,cm, m, km; g, kg; ml, l) by developing benchmarks through hands on experiences and visual representations. (MD.A.1)
- Students will solve multi-step problems involving measurement and conversion of measurements from a larger unit to a smaller unit using mm, cm, m, km; g, kg; ml, l. (MD.A.1)(MD.A.2)
- Students will record measurement equivalents using a two column table (conversion table) to use as a tool for problem solving. (MD.A.1)
- Students will apply area and perimeter formulas to solve real world problems. (MD.A.3)
