3rd Class Mathematical Explorers: Building Number and Space
A comprehensive third class curriculum focusing on the transition from concrete to abstract mathematical thinking. Students develop fluency in multiplication, explore the properties of 2D and 3D shapes, and apply data handling skills to real world scenarios.
The Power of Place Value and Operations
Students extend their understanding of the base ten system to 999 and develop flexible strategies for addition and subtraction.
Exploring the relationship between units, tens, and hundreds through regrouping and decomposition.
Moving beyond standard algorithms to use mental strategies and estimation for solving problems.
Developing a sense of number magnitude by rounding to the nearest ten or hundred.
Multiplication and Algebraic Thinking
Introducing multiplication as repeated addition and exploring patterns in the hundred square.
Visualizing multiplication through rows and columns to understand the commutative property.
Identifying and extending patterns in number sequences and spatial arrangements.
Understanding the equals sign as a balance rather than an instruction to calculate.
Geometry and Spatial Reasoning
Investigating the properties of 2D shapes and 3D objects in the environment.
Classifying polygons based on sides, angles, and symmetry.
Identifying faces, edges, and vertices of prisms, pyramids, and curved solids.
Introducing the concept of an angle as a measure of rotation.
Measurement in the Real World
Using standard units to measure length, weight, capacity, and time.
Measuring in meters and centimeters and calculating the distance around a shape.
Reading analog and digital clocks and calculating elapsed time.
Estimating and measuring mass in kilograms and volume in liters.
Data Handling and Probability
Collecting, representing, and interpreting data to answer questions and make predictions.
Creating bar charts and pictograms to display information clearly.
Analyzing graphs to find the mode and draw conclusions.
Using mathematical language to describe the likelihood of events.
