Ahh, the early stages of learning about number... Easy, right? And yet at that age, learning about 1 less isn't as easy as it sounds! So we've created some supporting activities to give children extra opportunities to develop their skills when learning about 1 less. Our Year 1 1 Less support worksheet is a completely practical activity - here, playing cards are needed - and frames the step in a collaborative context so children can discuss the task and have fun at the same time. Perfect for small-group interventions, this resource will hopefully leave (at least) 1 less child unsure about finding 1 less.
