10.1 Review: Length
Rationale
This lesson is important to teach in third grade because learning the U.S. customary system is an essential life skill and used throughout grade levels.
Objectives
Academic Standards *To provide a review of units, tools, and measuring length in U.S. customary and systems.
3.M.2: Choose and use appropriate units and tools to estimate and measure length, weight, and temperature. Estimate and measure length to a quarter- inch, weight in pounds, and temperature in degrees Celsius and Fahrenheit.
Materials to Collect and Preparation
Before Teaching Teaching the Lesson
• Math Journal pages 240 and 243
Ongoing Learning and Practice
• Math worksheet
• Posters
• Rulers
• Masking Tape
• Yardstick …show more content…
I will reference this poster to compare the size of each unit when talking about distance.
Discussing tools Used to Measure Distances
• *Ask children to name tools for measuring distances. SA: Rulers, yardsticks, and tape measures.
Show class these tools that were brought in.
Ask the class these questions about tools used to measure:
Would it make sense to measure the distance between Terre Haute and Indianapolis with a yardstick? SA: No
How could you measure the distance around a jar of a lid? SA: With a tape measurer
All of these measure units of distance but there are different tools that work better for different lengths.
Guided Practice:
I will pass out a worksheet to the class. I will use the Elmo to project the worksheet onto the screen. This worksheet will have different types of lengths and conversions. We will work together on a few problems and then the class will be responsible for completing questions on their own. When students have finished completing the problem independently we will collectively go over the answers and our work.
* I will watch for children who need support with reading a ruler and with
