part-whole model
The pegs and boards naturally decompose all numbers over 5 into two or more parts. This helps children to learn to conceptually subitise numbers as they will need to break numbers into chunks of 5 or less to be able to see them without the need to count. The pegs and boards compose numbers in the same way that we do with our fingers which gives children a link to an already meaningful, subitisable representation of numbers that they always have access to.
The part-whole model is important for children to make connections between addition and subtraction and develop an understanding of the relationship between numbers.
Flexible addition
The journey of developing a sense of numerosity, starting with links to the fingers, exploring decomposition of numbers and finally working flexibly with numbers to add across 10 (or bridge 10). As the resources are flexible and visual, they allow children to work physically with numbers before visualising and manipulating these operations in their head.
Flexible addition - Multiple Methods
Working flexibly with numbers to find multiple, efficient ways to calculate 13 + 8. This clip shows 3 techniques:
- bridging 10
- partitioning 13 and regrouping
- links to adding 10
The Spot On With Numbers pegs and boards offer a tactile solution for mental concepts which develops fluency with numbers.
fractions of quantities
This child was able to quickly make 24 with the boards already loaded and then saw that she could easily divide it between the three sections in the bar model. 2 groups of 8 was instantly recognisable as 16 as she saw 2 fives and 2 threes.
