Unit 3
Measurement, Time, and Graphs

* Measure length in inches, half inches, and quarter inches with rulers.
* Use customary units of liquid volume.
* Use metric units of liquid volume.
* Measure and estimate weight and mass.
* Solve word problems involving liquid volume and mass.
* Tell and write time to the minute, quarter hour, half hour and hour.
* Before and After the Hour
* Elapsed Time
* Add and subtract time.
* Solve word problems involving time.
* Read and create pictographs and bar graphs.
* Read and create bar graphs with multi-digit numbers.
* Represent and organize data
* Use graphs to solve time and measurement word problems.



In this unit, students explore customary and metric measurement, time concepts, and graphing. Students extend their measurement skills for length, capacity, weight, and mass. They measure lengths to a quarter inch and add, subtract, multiply, and divide measurements to solve problems. Students learn to tell time to the hour, half hour, quarter hour, five minutes, and one minute, as well as find elapsed time. Students represent time on a clock as well as a number line and use these models to solve problems. This unit also presents opportunities to explore categorical data displayed on tables, pictographs, bar graphs, and line plots. In Grade 3, students' work  with data and time is closely related to fraction concepts, computations with the four operations, and the number line.

They will learn to visualize staple images to help them remember about how much specific metric unit are worth.

The following are the staple images they will be taught 

Gram = one paperclip
Kilogram = one heavy book
Milliliter =  an eyedropper of water
Liter = a big bottle of water or Gatorade bottle

** 1 kilogram = 1000 grams
** 1liter = 1000 milliliters
