Mark shows strong numeracy skills in some areas like numeral identification and counting by 10s and 100s, meeting many of the NSW syllabus requirements for stage 1. However, he needs practice in other areas such as addition, subtraction, place value and multiplication/division in order to fully meet stage 1 requirements and begin working on stage 2 goals. The teacher should use tools like number lines, hundreds charts, dice and grouping objects to help Mark strengthen weaker skills and move his learning forward.
