To use the Times Table Tester, choose the level of difficulty (Easier, Harder or Megahard) and click on it. Type the answer to the equation in the white box and press “Check”. If the answer is incorrect, a message will appear next to the box indicating whether it is too high or too low. The question can be answered as many times as is needed to get to the correct answer. When playing the “Megahard” level, students will have to use a variety of multiplication strategies to get to the correct answer.
