Assessment

Learning Outcome 1: The learner will be able to recognise, describe and represent numbers and their relationships, and to count, estimate, calculate and check with competence and confidence in solving problems.

Assessment Standard 1.10: We know this when the learner recognises and represents the following numbers in order to describe and compare them:

1.10.3: whole numbers to at least 9-digit numbers.
