Differentiated boards for fun, strategic games to consolidate doubling and halving two-digit numbers. A4 and A3 versions included for all games. ALL ANSWERS INCLUDED.Intended to be laminated and used again and again. Two players per board (or 4 if working in a pair). Opponents take it in turns to double (or halve – depending on which game they’re playing) a number on the board. Using a different coloured whiteboard pen from each other, they mark the answer in the appropriate box. The numbers to be doubled or halved will print fairly faintly on the grid so that they don't get in the way of the children's answers. If different coloured pens are not available, children could put their initial or a symbol on the box too. First to get 4 in a row – vertically, horizontally, diagonally – wins. This pack includes: • A one-star version of both the doubling and halving game for younger or lower ability pupils - sidebars are included, featuring all answers, which children can strike through when used. However, I have also included this version without the answer sidebars in case your pupils don’t need this added support. This version focuses on lower 2-digit numbers and multiples of 10.• 2 different two-star versions of both the doubling and halving game.• All games are provided in both A4 and A3 format.• Answer grids are also provided – at the end of the A4 files.
