Number 20 - CanDo Bonds

The CanDo Bonds activity is a creative and interactive way for children to learn and practice number bonds to 20. The task encourages learners to use their knowledge of number bonds to 10 as a foundation to create and understand number bonds to 20. The activity includes a variety of exercises such as colouring, joining, and jotting down numbers to reinforce learning. For example, children are asked to complete number sentences and dominoes, ensuring that the sum of each pair of numbers equals 20. They may jot down dots or write the actual number to represent the quantities in each part of the bond.

Additional elements of the activity involve colouring in parts of an illustration based on the sums calculated. For instance, if the sum of two numbers on a character's antlers equals 20, the child can colour its nose. There's also a grid-based exercise where colouring boxes with a total of 20 helps to create a path across the grid. Furthermore, the resource provides bar models to help visualise the number bonds, and children are encouraged to write as many number sentences as possible based on their part-part-whole models. The activity also includes real-life word problems involving the number 20, such as calculating total spending and differences in age, which help to contextualise the mathematical concept in everyday situations. This comprehensive approach to learning number bonds is designed to enhance a child's numerical fluency and confidence in handling basic arithmetic involving the number 20.
