Study Notes
Number System
- Place value: Understanding the value of a digit based on its position in a number.
- Expanded form: Expressing a number as the sum of the values of its digits.
- Roman numerals: A system of numerical notation using letters (I, V, X, L, C, D, M).
- Comparing numbers: Determining the relative size of numbers using symbols like <, >, and =.
- Rounding off numbers: Approximating a number to a specified place value.
- Estimation: Finding an approximate value for a calculation, often using rounding.
- Factors: Numbers that divide another number evenly.
- Multiples: Numbers that are products of another number.
- Prime numbers: Numbers greater than 1 that have only two factors, 1 and themselves.
- Composite numbers: Numbers greater than 1 that have more than two factors.
- Identifying patterns in number sequences.
Addition and Subtraction
- Properties of addition: Commutative property (order doesn't matter), associative property (grouping doesn't matter), identity property (adding zero doesn't change the number).
- Properties of subtraction: Subtraction does not have the same commutative and associative properties as addition.
- Word problems involving addition and subtraction.
- Estimating sums and differences.
- Carrying and borrowing in multi-digit addition and subtraction.
Multiplication
- Multiplication facts: Memorizing multiplication tables.
- Multiplying by 10, 100, and 1000 and their multiples.
- Multiplication properties: Commutative property (order doesn't matter), associative property (grouping doesn't matter), distributive property (multiplying a sum), identity property (multiplying by 1).
- Word problems involving multiplication.
- Multiplying multi-digit numbers.
- Estimating products.
Division
- Division facts: Memorizing division facts.
- Division by 10, 100, and 1000.
- Division properties: Division by 1 is the number itself, division of 0 is 0, and division of a number by itself is 1.
- Word problems involving division.
- Long division.
- Estimating quotients.
Fractions
- Understanding fractions as parts of a whole.
- Equivalent fractions: Fractions that represent the same part of a whole.
- Comparing and ordering fractions.
- Addition and subtraction of like fractions.
- Addition and subtraction of unlike fractions.
- Multiplication of fractions by whole numbers and fractions by fractions.

Decimals
- Understanding decimals as parts of a whole.
- Place value in decimals.
- Comparing and ordering decimals.
- Addition and subtraction of decimals.
- Multiplication and division of decimals (by whole numbers and other decimals in limited cases).
Geometry
- Shapes: Identifying and classifying 2D shapes (triangles, quadrilaterals, circles, and other polygons).
- Understanding 3D shapes (cubes, cuboids, cylinders, cones, spheres).
- Lines: Identifying parallel, perpendicular, intersecting lines.
- Angles: Identifying acute, obtuse, right, and straight angles.
- Perimeter: Finding the distance around a 2D shape.
- Area: Finding the space enclosed by a 2D shape.
Measurement
- Units of length (millimeters, centimeters, meters, kilometers).
- Units of weight/mass (grams, kilograms).
- Units of capacity (milliliters, liters).
- Telling time (analog and digital clocks).
- Temperature (Celsius).
- Basic conversions between units.
Data Handling
- Collecting data.
