Pereira-Mendoza, Lionel – Arithmetic Teacher, 1984
Describes activities designed as self-checking tasks involving practice with whole number operations. Materials consist of a set of boards partitioned into 36 squares; sets of 36 sentence/picture cards correspond with each board. A correct sentence or picture is then formed as students correctly perform the necessary mathematical operations. (JN)
