Year 4 Mathematics
A comprehensive Year 4 curriculum focusing on the development of multiplicative thinking, fractional reasoning, and geometric properties. Students engage in deep inquiry to connect mathematical concepts to real world problem solving and spatial analysis.

The Power of Place Value
Exploring the base ten system to ten thousand and understanding how digit position influences value in whole numbers and decimals.
Recognizing and representing numbers up to at least 10,000 using various physical and digital tools.
Introducing tenths and hundredths as part of a whole and linking them to common fractions.
Applying place value knowledge to round numbers and provide reasonable estimates for calculations.

Multiplicative Thinking
Moving beyond additive thinking to master multiplication facts and related division strategies through arrays and area models.
Developing fluency with multiplication facts up to 10 x 10 and understanding the inverse relationship with division.
Using visual area models to multiply two digit numbers by one digit numbers.
Solving division problems and interpreting what the remainder means in different contexts.

Fractions and Parts of the Whole
Investigating equivalent fractions and calculating fractions of a collection in practical scenarios.
Using number lines and area models to identify and create equivalent fractions.
Applying fractional understanding to find a set portion of a group of objects.
Modeling the addition and subtraction of fractions that share the same denominator.

Measuring the World
Developing precision in measuring length, mass, and capacity using metric units and understanding perimeter.
Selecting and using appropriate metric units for various measurement tasks.
Calculating the perimeter of regular and irregular shapes using various strategies.
Reading analog and digital clocks to the minute and calculating elapsed time.

Geometric Reasoning
Comparing angles, identifying symmetry, and classifying shapes based on their geometric properties.
Identifying right, acute, and obtuse angles in the environment and in shapes.
Identifying line and rotational symmetry in shapes and creating symmetric patterns.
Using grid references and directional language to locate positions and describe paths.

Data and Probability
Collecting and interpreting data using various displays and predicting the likelihood of outcomes.
Formulating questions, collecting data, and creating effective displays like side by side column graphs.
