What you need:
- A deck of cards with the face cards and jokers removed (aces count as 1s and 10s count as 0s).
What to do:
- Shuffle the cards and deal out 4 in a row. This represents a 4-digit number (eg. 3836).
- Ask your child to read you the number.
- Ask your child to round the number to the nearest 10
- Ask your child to round the number to the nearest 100
- Ask your child to round the number to the nearest 1000
- Ensure that your child understands the rules for rounding correctly. You round to whichever number is closest, but if the digit being rounded is a 5 then you round up, rather than down. For example 4125 rounded to the nearest 10 is 4130, not 4120.
What to expect your child to do:
- Read the number correctly.
- Accurately round numbers to the nearest 10, 100, or 1000.
Variations:
- Change the number of digits in the number.
