Use tables facts and place value to multiply multiples of 10 and 100 by 1 -digit numbers. We can see this happening on a place value grid… 2 × 9 = 18. . . 1000 s 10 s 1 s 1 1 8 0 8 0 2 × 900 = 1800 2 x 9 x 100 2 × 90 = 180 2 x 9 x 10 When we multiply by 10 or 100, the digits move to the left and we use 0 s to hold the ‘empty’ place. © hamilton-trust. org. uk 5 Year 4
