Tens-Frames Foam Connecting Boards (Set of 4)
Tens-Frames are two-by-five rectangular frames into which counters are placed to illustrate numbers less than or equal to ten, and are therefore very useful devices for developing number sense within the context of ten.
The use of ten-frames was developed by researchers such as Van de Walle (1988) and Bobis (1988). Various arrangements of counters on the tens-frames can be used to prompt different mental images of numbers and different mental strategies for manipulating these numbers, all in association with the numbers' relationship to ten.
Plenty of activities with tens-frames will enable children to automatically think of numbers less than ten in terms of their relationship to ten and to build a sound knowledge of the basic addition/subtraction facts for ten which are an integral part of mental calculation. Suggested activities included.
