© Hamilton Trust Keeping Up Term 3 Week 9 Day 2 Objective: Use the grid method to multiply two and three- digit numbers with one decimal place by single- digit numbers, e.g. 3.5 x 7, 6 x 23.4.

© Hamilton Trust Keeping Up Term 3 Week 9 Day 2 Multiply every number in this grid by 3… What do you notice?

© Hamilton Trust Keeping Up Term 3 Week 9 Day 2 3 x 26.4 = ? x Use a grid to solve this: _____ Remember that 3 × 0.4 is 1.2, i.e. a tenth of 12. Partition the number into 10s, 1s and 0.1s. Multiply each part. Add the totals.

© Hamilton Trust Keeping Up Term 3 Week 9 Day 2 Make up a calculation in the form □ × □□. □ trying to give an answer as near 50 as you can! But 50’s the limit… Don’t go over it!

© Hamilton Trust Keeping Up Term 3 Week 9 Day 2 Work individually, using the grid method. Solve any 5 calculations from these 8 :
