What if pupils find this a barrier?
Give pupils a 1-100 grid and ask them to start from 5 and chant all the numbers moving vertically downwards. What's the same and what is different about these numbers? Why?
Start at 92 and move vertically upwards. What's happening now?
Repeat for different numbers. Continue without the grids, counting on and back in tens and hundreds. Make this a regular feature of oral and mental starters for lessons.
