Note for Teachers: Support the learners in understanding multiplication when group size is a multiple of 10. Language of ‘tens’ is a useful way to think about this. For example: 16 × 10 = 16 Tens is 160 16 × 20 = 16 × 2 Tens = 32 Tens = 320 Chapter 13.indd 188 Chapter 13.indd 188 3/26/2025 4:18:55 PM 3/26/2025 4:18:55 PMRead More
