8   Introduction DOUBLE TAP TO ZOOM WITH PHONE OR TABLET experiences to help children understand the mathematical relationships be- tween the concepts. After providing meaningful experiences related to the first photograph presented, a teacher can then revisit the tree with photographs taken from different angles. Incorporating this strategy benefits the children in that the new photographs reveal other mathematical concepts that the chil- dren can investigate and represent with materials. By supporting children’s experiences with this tree study, teachers can ensure the students’ work is • mathematically rich, • cognitively demanding, and • promotes worthwhile tasks that “build connections they have not already learned” (Featherstone et. al. 2011, 58).
