in 2s, 3s, 4s, Know what happens when a up to 12 X 7 X 13 = 91 using long/short 5s, 7s, 8s, number is multiplied by zero or 12. multiplication: 7 X 10 = 70 10s, 25s one. 7 X 3 = 21 and 1000s _____ = 91 from zero. Use reordering to multiply three numbers. At this stage, the non-statutory guidance in the Count up national curriculum suggests teaching short and down in multiplication; however, the team feel that an tenths and expanded form of calculation (as set out above) hundredths. is be a better lead into long/short multiplication. Stage Counting Identify multiples and factors, Recall & use Relate multiplying 5: forwards including finding all factor pairs multiplication a 4/3/2-digit by 18 and of a number, and common facts for all 1/2-digit number X13 backwards factors of two numbers. times-tables with grid to using 24 in 2s, 3s, 4s, up to 12 X long 30 5s, 6s, 7s, 12. multiplication: 80 8s, 9s, 10s, 100 25s and 234 1000s from zero.
