Students calculate an exact square root and estimate approximate square roots by finding the length of the square flower bed of a given area, and give an explanation for their answers.
Task: Use understandings about heat energy and insulation to describe how adaptations help Emperor penguins survive in Antarctica. Assessment focus: adaptations for keeping warm in cold conditions.
Students explain the function of the veins, waxy layer of the upper surface of the leaf, how the shape of the leaf traps light energy and why the upper surface of the leaf is a darker green than the lower surface.
Students demonstrate their understanding of a graph showing the relationship between the cost of different bottles of drink and the amount each bottle contains. They then explain which bottle of drink is the best value for money paid.
Students formulate questions about glaciers and climate change to show awareness that informed opinions are based on inter-related aspects of evidence rather than individual instances.
A spatial pattern involving the area of a shape is represented by a table and a diagram. Students describe the rule in words and as an algebraic expression.
Task: Students place in order four beakers of copper sulphate solution from most to least concentrated. They then explain what would happen if two beakers were put together, and explain the term "concentration". Assessment focus: solutions.
Students use substitution into equations to evaluate the number of blocks and total surface areas in shapes of different heights.
The stimulus can be used as a challenging task to try and derive the rules from the spatial pattern. This is classified as Patterns and Relationships.
Students construct a composite bar graph on areas of female employment in 1956 and 1996. They also answer questions interpreting and comparing the data.
