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 complete a table showing the number of counters used to make a series of L-shapes. They identify the number of counters needed for different situations, and describe the relationship as a rule.
Students investigate energy transfer by colliding marbles, explaining their observations, and what happens to the energy of the moving marble on impact.
This practical task assesses students' ability to record and graph data, and draw conclusions, as they conduct an experiment on the rate at which an ice cube melts in different temperatures.
Students are required to construct a composite bar graph based on Statistics New Zealand Time Use Survey data and are then required to make comparative statements based on gender.
In this practical task, students design a tally chart to record the number of different coloured ice-block sticks in an envelope. Students use the sticks as tally marks.
Students conduct a practical, statistical investigation. They decide on a question, categories, conduct the survey, tally and graph the results on a bar graph.
Students listen to instructions on where to go when visiting the zoo, then draw the path on a map. The assessment focus is on listening, recalling, and following instructions.
In this practical task, students construct pyramid patterns using triangles. They then predict how many triangles would be needed for the next size pyramid and explain their rule.
For this practical students make observations on water flow from three holes set at different heights in a container. They also investigate the effect on water flow if the top is on or off the container.
Using a diagram of a torch, students explain the function of the following parts; cell, metal cone, metal strip, spring, and switch. Students also draw a circuit diagram for the torch.
Using information about comets, students label a diagram of a comet and draw the orbit of a comet and the position of the comet in two places in its orbit.
Students draw a graph from some information they are given about the heating of meths in a water bath. Students then explain in terms of particles what is happening for the sloping section and the flat section of the graph.
For this practical task students follow a plan to determine the effects of a weak acid on different building materials. Students need to put their results into a table and write a conclusion.
