Powers of 10
In this worksheet, children develop their understanding of place value by exploring the relationship between numbers in different columns. As well as adjacent columns, they look at columns that are further apart, for example considering the number of tens needed to make 2,000 and then multiples of 2,000. Children can use both place value charts and charts to support their understanding. Exchanging with place value counters as extra support is also helpful.
Ask,
"How can you tell if a number is a power of 10?"
"Is this number a multiple of a power of 10?" "How can you tell?"
Watch for:
Children may not realise that the overall effect of,
for example, × 10 followed by × 10 is × 100.
