Element Sudoku Games (Chemistry starter for GCSE and A Level)

These element sudoku games come in three different levels; easy, medium, and hard. There are twelve different element sudoku grids per level. Element sudoku is based on normal sudoku but instead of filling the grids with numbers 1-9, students have to fill the grids with elements 1-9 i.e. H to F. The principle is the same, elements can only appear once in each row, column, and mini grid. This is a great starter, numeracy task, gap filler or Christmas activity. I use this a lot with my AQA GCSE Chemistry students and my OCR A Level chemists for a fun starter. This could even be used as an extension task for KS3 students.
