# Rounding Cards

### Purpose:

Place Value, Stage 6

### 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 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:

• Accurately round numbers to the nearest 10, 100, or 1000.

### Variations:

• Change the number of digits in the number.
