Train your Brain! Mental math ppt

<p>Inspired by the Dr K’s Brain Training; I’ve made a PowerPoint containing 50 slides of quick fire calculations for practicing mental math (+ x -). Could easily be adapted by changing the numbers or operations. The slides are set to show for 4 seconds on screen before changing; this could be altered to give more or less time depending on the ability of the children. I work on aiming for accuracy first then speed.</p>
