# Illustrating the Mathematics Standards

#### Multiple Measures: Illustrating the year 3 standard

The following examples of student work illustrate achievement at the mathematics standards for year 3.

The task used in this illustration relates to achievement objectives for Number and for Geometry and Measurement from the mathematics and statistics learning area in The New Zealand Curriculum.

#### Multiple Measures

Give the students five oblong-shaped blocks of varying sizes (including a cube). They will need a standard 30 centimetre ruler with 1 centimetre markings. Ask them to carry out the following tasks:

1. Measure the length, width, and height of your blocks.
2. Choose one of your blocks and imagine that four of them are stacked on top of each other. How high would they be?

For year 4 and above:

3. Design a net for one of your blocks (so that if you cut out and fold up the net, it makes the block). On your net, label the lengths of the sides.

Some features of students’ work used to make judgments in relation to the mathematics standards are described below. There is also an illustration of the year 4 standard and an illustration of the year 5 standard for this task.

 New Zealand Curriculum: Level 2 National Standards: After three years at school In solving problems and modelling situations, students will: Number and Algebra use simple additive strategies with whole numbers and fractions (number strategies) Geometry and Measurement create and use appropriate units and devices to measure length, area, volume and capacity, weight (mass), turn (angle), temperature, and time partition and/or combine like measures and communicate them, using numbers and units (measurement) Number and Algebra apply basic addition facts and knowledge of place value and symmetry to: - combine or partition whole numbers - find fractions of sets, shapes, and quantities Geometry and Measurement measure the lengths, areas, volumes or capacities, and weights of objects and the duration of events, using linear whole-number scales and applying basic addition facts to standard units
