*Grade 5 Note: Challenge 1 features rigorous 3-digit by 3-digit multiplication problems for Cannon A (125 × 108 = 13,500) and Cannon B (142 × 105 = 14,910) to challenge students while mapping perfectly to the final code.
Students solve four division problems with remainders. The remainders reveal the hideout compass coordinates. Note that Grade 5 includes rigorous 2-digit divisors.
