<![CDATA[Low nutritional literacy and health numeracy in rural families have the potential to impact the quality of food choices and daily cooking practices. Exploratory interviews conducted in March 2025 with mothers participating in the Community-Based Nutritional Research Center (TBM) in Serut Village revealed limitations in understanding nutritional composition, serving sizes, and budget-based menu planning. This situation prompted the need for interventions to improve mothers' nutritional knowledge, attitudes, and practices (KAP) and to strengthen children's health numeracy. The “Healthy Menu, Right Numbers” community program was implemented through six meetings using a community-based participatory approach (CBPA) for two target groups: mothers (n=10) and preschool–elementary school children (n=50). The materials covered balanced nutrition, label literacy, menu preparation using local ingredients, and contextual numeracy (portion calculation, serving sizes, budget), with CALGIBRA as a simple calculation tool. The evaluation used a descriptive pre-post design without inferential testing. In the mother group (n=10), the mean score increased from 29.0±2.05 to 29.4±2.63 (Δ=+0.4; maximum 32), with 6 mothers improving and 4 decreasing slightly. In the child group (7 groups), three groups improved, three remained stable, and one decreased. The findings are descriptive and contextual, showing mild but consistent improvements in mothers and strengthening of contextual numeracy in children. Sustainability focuses on monthly monitoring and micro-coaching based on kitchen cases, with CALGIBRA as an innovation that supports independent numeracy practice.]]>
