Multiplication Speed Maths! We are practising automatic recall of our multiplication facts to 12! You might like to take a screenshot of the grid and fill it in using another app. Step 1: Choose your grid. (Grid 1 is slightly smaller 7 x 8 size - Gride 2 is 10 x 10 size) Step 2: Set a 5 minute timer for speed maths! (You can also just go at your own pace if you don't want to time) Step 3: Tap when you are done.
