Chapter 5 The Study Of Numbers Up To 10

The Four Operations With Numbers Up To 5 The first exercise is concerned with measuring the ten rods with the white one as the unit and introducing the relevant numerical notation. This is followed by exercises involving the formation and writing down of mats. In exercises 2 – 10, addition and subtraction are introduced almost simultaneously. In exercise 2, the sign ‘plus’ is used. In the next exercise the ‘minus’ sign is introduced; rod patterns for both addition and subtraction are to be read in correct mathematical language, and the correct reading of mathematical symbols (3 – 2 = 1 and 2 – 1 = 1) is required. Exercise 4 includes problems (patterns to be completed in writing) involving almost all the possible variations on the addition and subtraction of the numbers 1, 2 and 3. Both reading and writing of mats involving numbers up to 5 are required in exercise 8; pupils read the written symbols in both 8 and 9, and complete patterns in writing in 7, 8 and 10. The brief outline of these few exercises will indicate the importance of understanding the background and general principles of the Cuisenaire-Gattegno method before attempting the classroom use of the Mathematics series of books. Multiplication in connection with numbers up to 5 is the subject of exercises 11-18, which also include a variety of problems in mixed operations. In exercises 19-41, both types of division are considered, that is,
