Group 1 metals High School tarsia - differentiated - covers ions, protons, flame colours, reactivity

This is a fully differentiated High School Chemistry tarsia puzzle for revision of the alkali metals. It is a fun kinesthetic way of revising the alkali metals. This sort of revision activity is particularly useful for boys. Answers are provided as well an 'easy start' that provides 4 of the 16 triangles as a starting point for weaker students. The 'group 1 metals A4 2 page' is an A4 tarsia that has 8 triangles per page. I suggest that these are printed on card and students cut them out. They are great for AFL. end of lesson plenary or plenary. If the writing of the A4 tarsia is too small then use the medium version. Please rate this resource and leave feedback.
