SCOTTS PRIMARY SCHOOL Using Tables Times table knowledge is vital for multiplying and dividing. We often use facts to help in calculations 16 x 8 = (8 x 8 = 64, so 16 x 8 must be128) 11 x 13 = 10 x 13 = 130 + 11 = 141 MATHS WORKSHOP FOR PARENTS
SCOTTS PRIMARY SCHOOL The Factor Method Years 3 and 4 also use this, although in a simple form Children need good tables knowledge 30 x 12 = 30 x (6 x 2) or (3 x 4) 30 x 6 = 180 x 2 = 360 MATHS WORKSHOP FOR PARENTS
