This is a set of 20 task cards designed for kids just learning how to multiply a number by a power of ten. Each card presents a number multiplied by a power of ten, or presents the "before" and "after" number for the kids to determine which power of ten was used. All powers of ten are positive. Some starting numbers are whole numbers and others are decimals. The preview title slide show both formats used for the cards.
These were designed to support the grade 5 Common Core standard 5.NBT.3. My district is just transitioning to the core standards, and these are in use by the teachers on my team as kids first learn how to use the power of ten notation in combination with how the digits in a number shift when multiplying by a power of ten.
These cards will also be offered in a bundle with my other set of powers of ten task cards.
This is a 7-page PDF file that contains 20 cards (4 per page for 5 pages), a 1-page recording sheet, and 1-page answer key.
