GROWN-UPS' DUGOUT
What this app practices.
Short, positive practice built around concrete pictures before abstract facts.
Multiplication is a bridge
Formal multiplication is not usually a Primary 1 core expectation. “Equal Groups” introduces × through repeated addition with 2s, 5s, and 10s.
Positive coaching
A missed answer never loses a run. The same pitch stays up with a helpful picture and an invitation to try again.
