This study presents findings from analyses of naturally occurring literacy events, where children jointly focus on reading and writing letters of the alphabet, illustrating social constructions of learning created through language and embodied action. Video recorded data from two different families living in an urban low-income area in Tanzania is presented to illustrate the findings. The analysis shows how participation frameworks are negotiated in terms of symmetries and asymmetries between younger and older siblings with both older and younger siblings initiating these frameworks: older siblings using different directives to guide the younger child's focus of attention and younger children both following and resisting such strategies.
