Complete: I have _____________________________________ correct!!
Can you remember what numbering system we make use of today?
____________________________________________________________________
The ancient Romans developed their counting system more than 2 000 years ago and some of their numbers looked like this: I ; II ; III ; IV ; V
Work with a friend and take turns to count in:
2.1 tens from 19 870 to 20 040
2.2 hundreds from 67 403 backwards to 65 903
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 1.9: We know this when the learner performs mental calculations involving:
1.9.1: addition and subtraction;
1.9.2: multiplication of whole numbers to at least 12 x 12.
