Extra reduction. solved.
From the innovators who brought you Times Tables Rock Stars comes a very interesting platform to learn to add and subtract… NumBots!
NumBots are about every child achieving a “triple win” in comprehension, memory, and fluency in mental addition and subtraction, so they go from counting to counting.
Suitable from Year 1 (UK) or Kindergarten (US) onwards. Younger players will be able to access the early stages from a math point of view but will find it increasingly difficult to reach the level of fluency required to make progress.
