What if pupils find this a barrier?
Give pupils a 1-100 grid (or use Number Grid ITP - Zip file (462Kb)) and ask them to start from 5 and chant all the numbers moving vertically down the column. What's the same and what is different about these numbers? Why?
Start at 92 and move vertically up. What is happening now?
Repeat for different numbers.
Continue without the grids, counting on and back in tens and hundreds. Make this a regular feature of pre-starters for lessons.
Number Grid ITP - Zip file (462Kb) is useful for counting on and back in tens.
