2nd Year Foundations of Mathematical Thinking
A comprehensive exploration of mathematical concepts for Second Class students, focusing on developing fluency in number operations and spatial reasoning. Students engage in hands-on investigations to build a deep understanding of how mathematics describes and organizes the world around them.
The Power of Place Value
Students explore the base ten system to understand how the position of a digit determines its value up to 199.
Using concrete materials to represent and rename numbers within 200.
Developing strategies to compare three-digit numbers using relational vocabulary.
Learning to make sensible guesses and rounding numbers to the nearest ten.
Operations and Algebraic Patterns
Investigating the relationship between addition and subtraction and identifying patterns in sequences.
Exploring inverse operations and the commutative property of addition.
Using frames and symbols to represent missing numbers in equations.
Identifying, extending, and creating patterns in shapes and numbers.
Shape, Space, and Symmetry
Analyzing the properties of 2D and 3D shapes and exploring spatial relationships.
Identifying and classifying polygons based on sides, corners, and symmetry.
Investigating the faces, edges, and vertices of common three-dimensional objects.
Using mathematical language to describe position and give directions.
The Measure of Things
Developing practical skills in measuring length, weight, and capacity using standard units.
Using scales to compare and measure mass in grams and kilograms.
Estimating and measuring how much liquid a container can hold.
Time and Money in the Real World
Applying mathematical concepts to daily life through clock reading and financial literacy.
Reading analog and digital clocks to the hour, half-hour, and quarter-hour.
Calculating totals and change using Euro coins and notes up to 20 Euro.
Understanding the organization of days, weeks, and months.
Data and Chance
Collecting, representing, and interpreting information and exploring the likelihood of events.
Using tally marks and frequency tables to record observations.
Using the language of probability to describe the likelihood of outcomes.
