Miss Jaffary's maths- Can I identify one less and one more than a number within 20?

We have been identifying and representing numbers 1-20 using ten frames, base ten, counters, cubes and other objects, we have also looked at counting 10 and adding more. We are now going to look at what one less and one more looks like . We are focusing on numbers up to 20, after you have looked at one less and one more, you will have questions around this and other types of questions such as 4 less , 4 more, 3 less, 2 more and so on.
