Sequencing of instructions can be explored with students through the use of materials and resources. Describing translations, reflections and rotations of two-dimensional shapes and using this knowledge to identify symmetries between shapes can be extremely useful in help students understand simple algorithms. These activities also assit students in understanding programming and decomposition.
A useful activity that explores sequencing of instructions is playing a barrier game with shapes. Students are partnered up and have to communicate to their partner over the barrier. Instructing their partner how to create a random or specific shape using their shapes to complete the activity. Activities like these help students to reflect upon the importance of specific and sequential instructions.
