Teaching approaches

Gakuva’s recommended starting approach is selected. You can still compare every option.

1 approach

Selected Default Gakuva

Fluency means a quick, sure answer. Within 5, we want answers that come fast, not a full count from one every time. Finger counting is a backup, not the goal.

Spend about 10 minutes flashing six ready within-5 facts and aiming for quick answers.
