4th Grade Math: Numbers and Operations

Numbers and Operations

• Place Value:
  • Understand that in a multi-digit number, the digits in each place (hundreds, tens, ones) represent amounts of hundreds, tens, and ones.
  • Compare numbers using >, <, and =
• Rounding Numbers:
  • Round numbers to the nearest ten, hundred, or thousand.
  • Understand that rounding a number can change its value.
• Multiplication and Division:
  • Multiply multi-digit numbers by single-digit numbers.
  • Divide multi-digit numbers by single-digit numbers.
  • Understand the concept of multiplication as repeated addition.
  • Understand the concept of division as repeated subtraction.
• Fractions:
  • Introduce basic fractions (e.g., 1/2, 1/4) and their equivalent decimals.
  • Understand that fractions represent part of a whole.

Algebraic Thinking

• Patterns:
  • Identify and extend patterns using shapes, numbers, or objects.
  • Create and solve simple patterns using addition and subtraction.
• Equations:
  • Introduce basic equations (e.g., 2x = 6) and their solutions.
  • Understand that equations can be solved using addition, subtraction, multiplication, and division.

Measurement and Data

• Length and Capacity:
  • Convert between units of measurement (e.g., inches to feet, cups to pints).
  • Understand that units of measurement can be used to compare lengths and capacities.
• Time and Money:
  • Tell time to the nearest five minutes on an analog clock.
  • Make change with money using dollars, dimes, and nickels.
• Data Analysis:
  • Collect and organize data using charts, tables, and graphs.
  • Interpret and answer questions based on the data.

Geometry

• Shapes:
  • Identify and classify different types of triangles (e.g., equilateral, isosceles, right).
  • Identify and classify different types of quadrilaterals (e.g., rectangle, square, trapezoid).
• Properties:
  • Understand basic properties of shapes (e.g., number of sides, number of vertices).
  • Identify and describe the properties of different shapes.

Word Problems

• Multi-Step Problems:
  • Solve multi-step word problems using addition, subtraction, multiplication, and division.
  • Understand how to read and interpret word problems to determine the correct operation.
• Real-World Applications:
  • Apply mathematical concepts to real-world scenarios (e.g., shopping, cooking, building).
  • Understand how math is used in everyday life.

Nilai Tempat

• Dalam sebuah bilangan multi-digit, setiap digitnya mewakili jumlah pada setiap tempat (ratusan, puluhan, satuan) yang mewakili ratusan, puluhan, dan satuan.
• Membandingkan bilangan menggunakan > (lebih besar dari) untuk menunjukkan perbedaan nilai antara dua bilangan.
