- 5:00 Concept Dictionary - Length
- Teaching points extracted from worksheets showing the development of length concepts from Year 0 to Year 6
- 5:01 Millimetres, centimetres and metres
- Convert measurements mm to cm to m. Decide whether each item has been measured in mm, cm or m. Explain why millimetres, centimetres or metres would not be suitable units for measuring the distance from Sydney to Canberra, and state what else would not be measured in these units. State the length, width and perimeter of the photo. Estimate its area and the distance between opposite corners.
- 5:02 Converting mm, cm and m
- Name things that are shorter/ longer than given measurement. Write measurements in centimetres/ metres using the decimal form. Write measurements in millimetres/ centimetres. Complete the table, recording your height and the height of a friend. Write the heights in ascending order, using the decimal form in metres.
- 5:02C Measurement
- Draw a line from the dot to the given length. Draw a rectangle to the given length and width. Measure the side lengths of each shape and find the perimeter. Draw a shape to the given perimeter/ area. Write the name of an object that would be weighed using the different types of scales shown. Investigation using the internet or library: how cars, trucks, boats and large animals are weighed.
- 5:03 Perimeter and area
- Find the perimeter and area of rectangles/ square. Measure the length of the sides of each shape - triangle/ kite, and calculate its perimeter. Write the name of each shape.
- 5:03E Area and perimeter of rectangles
- Extension page. Find the area and perimeter of each rectangle. Use multiplication to show a quicker way to work out the perimeters of these shapes.
- 5:04 The kilometre
- Estimate and match each distance to the correct label - equal to, <, > 1 km. Circle the distances that would be measured in kilometres. State how many metres make up each fraction of a kilometre as given. Colour the correct answer in each case: more than, less than, about 1 km. Use a street directory to estimate distances as directed. Estimate the perimeter of your school. Use a trundle wheel to measure this perimeter.
- 5:05 Measuring length
- Change kilometres to metres/ metres to kilometres. Write distances in m/ km. Circle the longer distance. On the number line, match each distance to its position from the start.
- 5:06 Kilometres and speed
- Road speed signs - km/h. If you travelled for 1 hour at the speed shown, how many kilometres would you cover? Write your speed in each case. Complete the table to show the distance travelled. Estimate the number of kilometres that would be travelled in one hour by given animals and write in km/h. State speed in km/h if I travel the distances and number of hours given.
- 5:06E Speed
- Extension page. Write the speed using the short form - km/h or m/s, metres per second. Solve the word problems.
- 5:06PT Progress test
- Test of Length
- 5:07 Area and perimeter of rectangles
- Find the area of these shapes using the formula - Area = Length multiplied by Breadth. Measure the sides of shapes and find the area and perimeter of each. Draw another rectangle with the same perimeter, is the Area the same?
- 5:08 Kilometres
- Order the distances from shortest to longest. Write the distances in metres. Complete these tables, converting between km and m. Write the distances using decimal notation.
- 5:08PT Progress test
- Test of Length
- 5:09 Measuring devices
- 5:10 Perimeters
- Measure the sides of each shape and find its perimeter - rectangle, triangle, square, parallelogram, rhombus, regular hexagon. Complete the missing lengths and find the perimeter. Write a quick method of finding the perimeter of square, rectangle, regular octagon, regular hexagon, isosceles triangle.
- 5:10E Perimeters
- Extension page. Complete tables for perimeters of squares and rectangles - using rules: The perimeter of a square is equal to the length of its side multiplied by four. The perimeter of a rectangle is twice the sum of its length and breadth. Find the perimeter of the regular shapes and write the quick way to find perimeter of equilateral triangle, regular hexagon, regular pentagon, regular octagon. Measure the sides of each isosceles triangle and find its perimeter.
