• Building number sense through varied practice and real-world applications

Measurement and Data
Students explore fundamental measurement concepts including:

• Length and height comparisons using standard units
• Distance measurement and estimation
• Practical measuring activities using everyday objects
• Problem-solving with measurement scenarios

Time Concepts
Young learners develop essential time-telling skills through:

• Reading analog and digital clocks
• Understanding hours and half-hours
• Connecting time concepts to daily activities
• Solving simple time-related problems

Comprehensive Teacher Support Materials
The accompanying teacher's resources provide everything needed for effective instruction:

• Clear learning outcomes and vocabulary for each lesson
• Detailed board plans and journal prompts
• Strategic recall activities to reinforce previous learning
