FREE to new buyers: enter code SEPTEMBER-SAVER at checkout. 6 boards for fun, strategic and differentiated Four in a Row games to consolidate doubling and halving of two- (and some three-) digit numbers. All boards available in colour and black and white. Originally designed for Key Stage 2 (KS2). ALL ANSWERS INCLUDED.
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, more challenging versions of both the doubling and halving boards (two-star versions).
Intended to be laminated and used again and again. Two players per board (or 4 if working in a pair). Printing in A3 size is a good idea for a larger group but A4 will work too. Opponents take it in turns to double (or find half of– 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. It works particularly well if they roll a dice to determine which column they must answer a question in (the columns are numbered 1-6). If the column they've rolled has all been completed, they could either roll again or miss a go. 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.
In my TES shop I also have several other differentiated, fun resources for finding double and half of 2/3-digit numbers, available with this resource in a bundle. You can follow the links to get more information about the individual resources: Doubling and Halving Games Bundle
