At flying start we use Numicon to support children’s development in maths. 
The shapes and and colours of the pieces allow children to visualise number and learn about simple number bonds. When building towers using the pegs, starting with the number 10 piece, they use a variety of combinations of the smaller pieces to allow them to fit. So, 7 +3 will fit on the tower, 4+6 and so on. The children enjoy making the towers, and without knowing, they gain an awareness of simple number bonds.
