Multiplying by 10, 100 and 1,000 — Interactive Lesson & Activities (Year 5)

Why does 4.5 × 10 become 45, not 4.50? This 28-slide interactive lesson teaches multiplying by 10, 100 and 1,000 by showing exactly how digits shift on a place value table.

Mastering Multiplying by 10, 100 and 1,000 in Year 5 Maths

Pupils understand the concept of multiplying by 10, 100 and 1,000, perform multiplications that shift digits one, two or three places to the left, and recognise the connection between these multiplications and place value. They see that multiplying by 10 moves every digit one place left, so 4.5 × 10 becomes 45, and that multiplying by 100 moves every digit two places left, so 49.1 × 100 becomes 4,910, then apply this to calculations such as 47.14 × 10 and 3,234 × 10.
