6. • Numbers up to 20 are represented by means of structural models: - line model - group model - combination model • Recognize without counting an arranged quantity up to 20, with 5- or 10-structure in different visualizations: - fingers - dots - bead string - arithmetic rack • Recognise without counting a number of objects up to 6 • Estimate and then count a number of objects up to 10 • Recognise different arrangements of objects representing the same number • Learn recognition and re-arranging skills to handle spatial relationships and patterns • Subitising (identify the number of given objects without counting) • Use n umbers in different meanings and functions: - Magnitude - Order number - Measure number - Label number - Calculation number • Read, pronounce and identify any number on the number chart and number line up to 54 • Read the number names in groups and individually up to ten • Trace, copy and write numbers 0-10 • Recognise, read and understand numbers and practice numerical notation • Numbers • Express orally and in mathematical symbols their understanding of number patterns (order, sequence, and spatial relationships) within the number range 0-54 • Levels of counting: - Context bound counting-and-calculating - Object bound counting-and-calculating - Pure counting-and-calculating via symbolization • Count concrete objects up to 20 and backwards from 10-0 • Count concrete objects in 2 s up to 20 • Count mechanically up to 54; mechanically in 2s up to 20; in 5s and 10s up to 50; backwards from 10 to 0 • Construct number concept by associating numbers with objects while counting • Appreciate and understand the need and convenience of counting in everyday life • Counting NUMBER CONCEPT DEVELOPMENT GRADE 1 BASIC COMPETENCIES By the end of Grade 1, the learners can: APPROACHES RME (RME: Realistic Mathematic Education) APPROACHES Suggested activities that could lead to achieving the competencies LEARNING OBJECTIVES Learners will: THEMES AND TOPICS
