Little paper discoveries, together
Six public parent-led lessons: three math discoveries and three reading adventures with sounds, sh, and two-part words. A grown-up reads; the learner draws, folds, points, or tells. Paired Parent Guides and printable manual logs are included.
No sign-in needed. These are selected activities, not K–2 enrollment, full courses, or saved learning.
