Learning unit 1 Week 1
Day 3 Session 1: Number names and number symbols The learners should be familiar with double numbers such as 52. Just as they learned to count in hundreds, remind them that the words ‘100’, ‘200’, ‘300’, etc. can be said and written in front of the numbers 1 to 99, for example: 152 is a hundred and fifty-two and 223 is two hundred and twentythree. As soon as the learners understand this, they will be able to extend their number concept to 1 000.

Count from 100 to 150. Give the learners the opportunity to write number names between 0 and 200 on the board, for example: ‘twenty-five’ or ‘a hundred and thirty-one’. Each learner must get a turn.
Session 2: Addition with place values Write the example sum from activity 6 in workbook 1 on the board. Explain to the learners that there is an easy way to add big numbers. Break down each number into tens and ones. First add the tens together, then add the ones together and then add the tens and ones together. The learners do not have to write down the whole calculation, but can do the calculation in their heads. The sums will thus be 60 + 20 and 2 + 7.
62 + 27 = (60 + 2) + (20 + 7) = 80 + 9 = 89 Complete activity 6 in workbook 1. The learners break down the numbers to complete the addition sums.
