Target Numbers Stage 8 Recording Sheet

Narrative
Students add hundredths and tenths to get as close to 1 as possible. Students start their first equation with 0 and take turns rolling a number cube and choosing whether to add that number of hundredths or tenths and write an equation. The sum becomes the first number in the next equation. The player who gets closest to 1 in 6 rounds, without going over 1, is the winner.
Additional Information
Each group of 2 needs one number cube.
