Year 8 - Measurement and Geometry

Standard 8.MD.1.1 - Practice calculating the perimeter and radius of a circle based on the dimensions of a quarter circle.

Included Skills:

Using units of measurement
• Choose appropriate units of measurement for area and volume and convert from one unit to another
- choosing units for area including mm2, cm2, m2, hectares, km2, and units for volume including mm3, cm3, m3
- recognising that the conversion factors for area units are the squares of those for the corresponding linear units
- recognising that the conversion factors for volume units are the cubes of those for the corresponding linear units
• Find perimeters and areas of parallelograms, trapeziums, rhombuses and kites
- establishing and using formulas for areas such as trapeziums, rhombuses and kites
• Investigate the relationship between features of circles such as circumference, area, radius and diameter. Use formulas to solve problems involving circumference and area
- investigating the circumference and area of circles with materials or by measuring, to establish an understanding of formulas
- investigating the area of circles using a square grid or by rearranging a circle divided into sectors
• Develop formulas for volumes of rectangular and triangular prisms and prisms in general. Use formulas to solve problems involving volume
- investigating the relationship between volumes of rectangular and triangular prisms
• Solve problems involving duration, including using 12- and 24-hour time within a single time zone
- identifying regions in Australia and countries in Asia that are in the same time zone
