Difference Tally

Difference Tally is a Grade 5 decimal subtraction game that builds two decimals from card draws and subtracts the smaller from the larger. Students work to the hundredths place, record each difference, and use those results as part of the game’s scoring. Constructing both numbers first makes decimal place value part of the subtraction task.

Use it with partners or a small group when students need repeated practice lining up decimal places and checking reasonable differences. Encourage estimation before subtraction to catch errors.
