Bring Chinese New Year into your math lesson with this interactive partial sums game! Students practice double-digit addition by selecting two red packets and visually breaking numbers into tens and ones. Important: This game intentionally uses problems WITHOUT regrouping/carrying (ones digits sum to 4 or less), making it ideal for introducing the partial sums strategy before adding the complexity of regrouping. The clear visual representations show grouped packets of 10, step-by-step addition practice, and immediate feedback. Features two difficulty levels (Easy: $10-$20, Medium: $20-$44), festive background music, and printable assessment receipts with standards alignment.
