Activity: to examine and expand numeric patterns [lo 2.1]
1. Do you still remember how to find "patterns" in number rows? (Learning Unit 1) Work on your own - without a calculator - and see whether you can complete the following number patterns correctly:
1.1 6 850 ; 6 700 ; 6 550 ; .........................; .........................
1.2 14 360 ; ......................... ; ......................... ; 14 315 ; 14 300 ; ....................
1.3 122 500 ; ......................... ; 121 500 ; 121 000 ; ......................
Assessment
