  • Hi, this resource was very useful for addition. Is there something similar for the other operations? ie having 2 x 1 / 3 x 1 digit multiplications

    • Hi n.palmer,
      Thanks for your lovely request - I'll ask our design team to take a look and see if we can make this change for you :) In the meantime, there is an editable version of this resource in the 'Alternative versions' box below the pink 'Download' button if you would like to have a go at creating your own estimate answer speed challenges!

  • I don't understand how 17+ 39 from list 1 can be estimated to an answer of 50-60? How is this within an allowable range?  Every answer is subtraction when the Qs in the challenge are addition? Is there an inverse skill as well?  I am very confused!

    • Hi erialcrobo,
      Thank you very much for commenting! It's great to hear from you :)
      This activity is for estimating answers quickly so the answer sheet gives an allowable range rather than a single answer. I hope this clears up the confusion!

  • The answer sheet is for something completely different?
