Number Lines - How to use Number Lines for Kids

Children make a natural progression from counting to basic addition - but there's a key moment along the way. It comes when they realize they don't have to count all the way from one each time.

Take the above example. Children start out by counting on fingers from one to three, then they count four more to get seven. There's nothing wrong with this method - it's a natural stage - but there's a bit of needless counting going on.

Soon they'll realise this and start at three and then count on to seven. Number lines are a great way to accelerate this development.

Number lines provide a mental strategy for addition and subtraction. It's easy to think of them as a kind of crutch for the struggling, but this is not so. Research has shown they're important because they promote good mental arithmetic strategies.

Learners soon graduate from using simple number lines to visualising one in their mind - this is when the humble number line has done its job!

We encourage using number lines in Komodo:
