1 more, 1 less

The interactive activities provided by Buzzard Publishing in their CanDoBonds collection offer a hands-on approach to understanding the concepts of 'one more' and 'one less'. Children are encouraged to engage with a variety of tasks that involve colouring, joining, jotting and shading to enhance their numerical skills. The 'one more' activities include colouring an additional circle in a sequence, completing number sentences, and solving problems that involve adding one to a given number. For example, children might be asked to determine how many bricks John has if he has one more than Tim's four. They also practice shading an extra cube in a set and using bar models to visually represent and solve addition problems.

Conversely, the 'one less' section of the activities focuses on the concept of subtraction by one. Children are invited to cross out a circle or cube to visually represent one less, complete number sentences that reflect this subtraction, and solve problems that require finding one less than a given number. For instance, they might calculate how many sandcastles remain after one is knocked down from a total of seven. These tasks are designed to reinforce the understanding of subtraction within a practical context, using part-part-whole models and bar models to support the children's learning. The activities are carefully crafted to ensure that children can grasp the relationship between numbers in a fun and engaging way.
