Number Sense

• Counting: Count forward and backward from any given number.
• Place Value: Understand tens and ones; recognize the value of digits in two-digit numbers.
• Comparing Numbers: Use symbols >, <, and = to compare numbers up to 100.

Addition and Subtraction

• Basic Operations:
  • Addition and subtraction within 20.
  • Solve word problems involving addition and subtraction.
• Strategies:
  • Use number lines, counting on, or counting back.
  • Doubles (e.g., 4 + 4) and near doubles (e.g., 4 + 5).

Word Problems

• Types of Problems:
  • Join problems (adding to).
  • Separate problems (taking away).
  • Part-part-whole problems.

Measurement

• Length: Understand and use non-standard units (e.g., paperclips, blocks) and standard units (inches, centimeters).
• Time: Read analog and digital clocks to the hour and half-hour.
• Money: Identify coins (pennies, nickels, dimes, quarters) and their values; solve simple money-related problems.

Geometry

• Shapes: Identify and describe 2D shapes (circle, square, triangle, rectangle) and 3D shapes (cube, sphere, cone).
• Attributes: Discuss properties of shapes (sides, corners, symmetry).

Patterns and Algebra

• Patterns: Recognize, create, and extend patterns using shapes, colors, or numbers.
• Basic Equations: Understand simple equations (e.g., 2 + ? = 5).

Data and Graphing

• Collecting Data: Gather information through surveys or observations.
• Graphing: Create and interpret simple bar graphs and pictographs.

Problem-Solving Strategies

• Multiple Approaches: Encourage using different methods to solve problems.
• Reasoning: Develop the ability to explain how problems were solved.

Pag-unawa sa mga Numero

• Pagbibilang: Makakabibilang mula sa anumang ibinigay na numero, parehong pasulong at pabalik.
• Halaga ng Posisyon: Nauunawaan ang tens at ones; mahalagang maipaliwanag ang halaga ng mga digit sa mga dalawang digit na numero.
• Paghahambing ng mga Numero: Gamitin ang mga simbolo gaya ng > (higit sa), < (mas mababa sa), at = (katumbas ng) upang ihambing ang halaga ng mga numero.
