These foam 2x5 frames into which thick, 2-coloured counters are placed, perfectly show numbers less than or equal to ten.
They enable children to automatically think of numbers less than ten in terms of their relationship to ten.
They can be used to develop pupils’ subitising skills; the ability to “instantly see how many”. This skill plays a fundamental role in the development of understanding of number. They can also help build a sound knowledge of the basic addition and subtraction facts for ten, which are an integral part of mental calculation.
The design of the frames gives opportunities for understanding two-digit numbers simply by linking two frames together. This placement of a second frame to the right of the first frame, supported by the later introduction of numeral cards, will further assist the development of place-value understanding.
