Content
Geometric measure A
Length: Use metres and kilometres for length and distances
Length: Connect decimal representations to the metric system
Length: Use metres and kilometres for length and distances
- Recognise the need for a formal unit longer than the metre for measuring distance
- Measure 100 metres and recognise that 10 times 100 metres is one kilometre, ie 1000 metres = 1 kilometre
- Estimate lengths and distances using an appropriate unit
- Record distances using the abbreviation for kilometres (km)
- Use a variety of measuring devices to measure lengths and distances in different contexts
- Use efficient strategies to calculate the perimeter of a large rectangular area in metres
- Calculate perimeters of common two-dimensional shapes, including squares, rectangles and triangles
- Determine which side lengths are needed to find the perimeter of a shape (Reasons about relations)
- Recognise that rectangles with the same perimeter may have different dimensions (Spatial reasoning)
Length: Connect decimal representations to the metric system
- Recognise the equivalence of whole-number and decimal representations of measurements of length
- Interpret decimal notation for lengths and distances
- Record lengths and distances using decimal notation
- Use decimal place value system to convert between metres and kilometres
- Convert measurements to the same unit to compare lengths and distances
- Explain and use the relationship between the size of a unit and the number of units needed
- Investigate and compare perimeters of rectangles with the same area
- Determine the number of different rectangles that can be formed using whole-number dimensions for a given area (Reasons about spatial structure)
- Solve a variety of problems involving length and perimeter, including problems involving different units of length
