You can incorporate incidental teaching during your everyday activities with your toddler.
We love going on a number hunt during our walks (or as carter likes to call it ‘number letterboxes’). As we are walking we stop at each letter box and as I point to the numbers, Carter tells me which one it is. At this stage he recognises single digit numbers, so for 15 he will tell us ‘1’ and ‘5’. It’s a great way to revise number recognition and get in some exercise at the same time!
