Race to 100

Last week in maths we spent a lot of time counting. We counted forwards, backwards, by 2s, by 5s, by 10s and more. We had a challenge race to count 100 sticks.
When we started we tried counting by 1s but when we finished Trish asked us to PROVE it. Mathematicians are able to prove how they get their answers so we had to think of.a way to do this.
After some hard thinking and trying some different ways of counting we came up with counting the sticks by 10s. This made counting to 100 really easy!! After that we even thought about counting by 20s. It is a lot like counting by 2s.
Do you know of a quick way to count to a target number?? What would you do if you had to count to 500.
