Number line subtraction - no problem! ✅⭐️
This littler learner was flying through the calculations tonight (independently)! Addition & subtraction within 20 using a number line for support..
How did we achieve this?
⭐️ Teach the method - how to use/ navigate the number line
⭐️ Explain the vocabulary - take away, subtract, count backwards, less than, fewer…
⭐️ Model examples - show them repeatedly, talking through your thinking out loud as you demonstrate
⭐️ Let them apply & practise - LOTS! Regularly come back to this method to ensure it’s embedded, as well as learning new strategies
If you don’t have access to a number line like this one, you can use a ruler in exactly the same way or print & laminate one to make it wipeable 😊🪄 putting one inside a plastic wallet also works too! *using a whiteboard marker 🖊️
