Background: Perceptual motor development is crucial during early childhood and not properly addressing it in physical education (PE) can be detrimental. Aim: To determine the effect of a South African curriculum-aligned PE intervention on the visual-motor integration (VMI), visual perception (VP) and motor coordination (MC) of 6-year-old children. Setting: Quintile 3 schools in Mangaung, Free State Province, South Africa. Methods: Grade 1 children from two quintile 3 schools in Mangaung were recruited. Complete data sets were obtained for 44 participants. A quantitative randomised control trial design was followed. The Beery-Buktenica Developmental Test of Visual-Motor Integration, Sixth Edition (Beery VMI-6), determined participants' VMI, VP and MC during the pre- and post-tests. The "KaziKidz" toolkit was used as intervention during 10 sessions of 40 min each for the experimental group, while the control group continued with the South African PE curriculum. The Fisher's exact and Kruskal--Wallis tests were used for pre- and post-test comparisons, with p < 0.05 indicating statistical significance. Results: The median age of the control (n = 18) and intervention (n = 26) groups was 6.7 and 6.5 years, respectively. Post intervention, the intervention group displayed significantly improved VMI (p = 0.042) and VP (p < 0.001), compared to the control group. No significant differences between the groups were observed for MC. Conclusion: Exposure to PE including perceptual motor aspects significantly improved the VMI and VP of 6-year-old children. Contribution: Results deemed the "KaziKidz" toolkit to be a successful mode of PE delivery to improve the perceptual skills of Grade 1 learners in South Africa.
