- comparing two or more quantities of the same kind (ratio);

- rounding off and compensating;
- doubling and halving;
- using a calculator.
- Uses a range of strategies to check solutions and judge the reasonableness of solutions.
- Recognises, describes and uses:
- the reciprocal relationship between multiplication and division
(e.g. if 5 x 3 = 15 then 15 ÷ 3 = 5 and 15 ÷ 5 = 3);
- the equivalence of division and fractions (e.g. 1 ÷ 8 = 1/8);
- the commutative, associative and distributive properties with whole numbers (the expectation is that learners should be able to use the properties and not necessarily know the names).
Learning Outcome 2: Patterns, Functions and Algebra
The learner will be able to recognise, describe and represent patterns and relationships, as well as to solve problems using algebraic language and skills.
Assessment standards
We know this when the learner:
- Investigates and extends numeric and geometric patterns looking for a relationship or rules, including patterns:
- represented in physical or diagrammatic form;
- not limited to sequences involving constant difference or ratio;
- found in natural and cultural contexts;
- of the learner’s own creation.
- Describes observed relationships or rules in own words.
- Determines output values for given input values using:
- verbal descriptions;
- flow diagrams.
- Writes number sentences to describe a problem situation, including problems within contexts that may be used to build awareness of human rights, social, economic, cultural and environmental issues.
- Solves or completes number sentences by inspection or by trial-and-improvement, checking the solutions by substitution (e.g.
÷ 4 = 12).
- Determines, through discussion and comparison, the equivalence of different descriptions of the same relationship or rule presented:
- verbally;
- in flow diagrams;
- by number sentences.
Learning Outcome 3: Space and Shape (Geometry)
The learner will be able to describe and represent characteristics and relationships between two-dimensional shapes and three-dimensional objects in a variety of orientations and positions.
Assessment standards
We know this when the learner:
- Recognises, visualises and names two-dimensional shapes and three-dimensional objects in natural and cultural forms and geometric settings including those previously dealt with and focusing on:
- similarities and differences between cubes and rectangular prisms;
- similarities and differences between squares and rectangles.
- Describes, sorts and compares two-dimensional shapes and three-dimensional objects from the environment and from drawings or pictures according to properties including:
- number and/or shape of faces;
- number and/or length of sides.
- Investigates and compares (alone and/or as a member of a group or team) two-dimensional shapes and three-dimensional objects studied in this grade according to properties listed above by:
- making models of geometric objects using polygons they have cut out;
- cutting open models or geometric objects (e.g. boxes) to trace their nets;
- drawing shapes on grid paper.
- Recognises, describes and performs rotations (turns), reflections (flips) and translations (slides) using geometric figures and solids.
- Makes two-dimensional shapes, three-dimensional objects and patterns from geometric shapes and describes these in terms of:
- tessellations;
- line and rotational symmetry;
- movement including rotations, reflections and translations.
- Recognises and describes natural and cultural two-dimensional shapes, three-dimensional objects and patterns in terms of geometric properties.

- measuring jugs to measure capacity;
- rulers, metre sticks, tape measures and trundle wheels to measure length;
- thermometers to measure temperature.
- Investigates and approximates (alone and/or as a member of a group or team):
- perimeter using rulers or measuring tapes;

Learning Outcome 5: Data Handling
The learner will be able to collect, summarise, display and critically analyse data in order to draw conclusions and make predictions, and to interpret and determine chance variation.
Assessment standards
We know this when the learner:
- Poses simple questions about own school and family environment, and identifies appropriate data sources in order to address human rights, social, political, cultural, environmental and economic issues in that environment.
- Makes and uses simple data collection sheets that involve counting objects in order to collect data (alone and/or as a member of a group or team) to answer questions posed by the teacher and the class.
- Organises and records data using tallies and tables.
- Examines ungrouped numerical data to determine the most frequently occurring score (mode) of the data set in order to describe central tendencies.
- Draws a variety of graphs to display and interpret data (ungrouped) including:
- pictographs with a many-one correspondence and appropriate keys (e.g. one picture = ten persons);
- bar graphs.
- Critically reads and interprets data presented in a variety of ways (including own representations, representations in the media - both words and graphs) to draw conclusions and make predictions sensitive to the role of:
- context (e.g. rural or urban);
