    Cattle Trains Cattle Trains Presentation Transcript

    • Area and Perimeter of the Nazi Cattle Trains
    • Learning Objectives Area of a Rectangle Perimeter of a Rectangle Estimation Area of a Triangle Empathy Cattle Trains Inhumane conditions KEYWORDS
      • The Cattle trains that took the Jewish victims of the Holocaust to the Concentration camps were crammed with people.
    • Area & Perimeter
      • What is Area?
      Area is the amount of space inside a shape What is Perimeter? Perimeter is the total distance around the outside of a shape
    • Task 1
      • Estimate the AREA and PERIMETER of the floor of one of the cattle trains taking the Jewish victims to their deaths.
        • TOP TIP -
      • What common things do you already know the size of (your height, the table, etc)?
      • Use your knowledge about the dimensions of these items to visualise and guess how big the train floor might be.
    • What Do I Need to Know? What are the names of these shapes? Which of these is the shape of the Cattle train?
    • How Do I Find The Area?
      • Area
      L W Area = L x W length width Rectangle L L Square Area = L x L length length
    • How do I find the Perimeter?
      • Perimeter
      L W Perimeter = L + L + W + W = 2L + 2W length width Rectangle L L Square Perimeter = L + L + L + L = 4L length
    • Task 2
      • We will now estimate how much area each person on the cattle train would need.
      • - TOP TIP -
      • Stand up tall! Imagine drawing a rectangle around your feet on the floor - this is the area we are measuring. Remember, your shoulders are wider than your feet!
      • How long are your feet in metres?
      • (e.g. 20cm=0.2m)
      • How wide are your shoulders?
    • Important
      • Your estimate of the area must have appropriate units of measurement and must be written with the squared symbol.
      • e.g. 2cm x 3cm = 6cm ²
      cm 2 mm 2 km 2 m 2
    • Putting it all together!
      • Once we have estimated the area of the cattle train floor and the amount of space you need we can now estimate how many people could fit in one cattle train.
      • train floor area ÷ area each person needs
      • E.g. 32m² ÷ 0.5m² = 64
      • Therefore 1 cattle train would hold 64 people.
    • Field Work
      • Now we will escape the classroom and measure the areas and perimeter accurately.
      • Answer these questions:
        • What is the area of the cattle train?
        • What is the perimeter of the cattle train?
        • What is the area each person requires?
        • How many people could actually be crammed into each train?
    • Plenary
      • How close were your estimates?
      • How could you improve your estimation skills?
      • What words could we use to describe what it must have been like to travel for hours on a cattle train in such conditions?
    • Extension 1
      • We now know how to calculate the area of a rectangle, but do we also know how to calculate the area of a triangle?
    • How Do I Find The Area? Any Triangle H H B B 2 Area = 1 B x H base height Or in other words; multiply the Base & Height together and then divide by 2
    • Extension Task 1A
      • On the worksheet , work out the area
      • of each of the shapes. You must show your workings out for each question
      ExtensionTask 1B Find 10 shapes around the room and then work out the area for each of them. E.g. it could be a door, table or book Remember to describe each shape
    • Extension Task 1C
      • How about COMPOUND shapes that are made up of more than one shape?
      • Using the knowledge you already have about areas of triangles and rectangles, have a go at the compound area worksheet .
    • Extension 2
      • So far we have been looking at AREA and PERIMETER which are 2D measures.
      • What do we call a 3-Dimensional measure of an object?
      • Click here for the ANSWER …
    • Plenary 2
      • What have we learnt in this lesson?
      • How does our ability to measure areas, perimeters and volumes help in our understanding of what the conditions were like for the Jews in the Cattle Trains?
