Rounding Cards

Purpose:

The purpose of this activity is to help your child practice rounding numbers.

Link to Number Framework:

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 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.
