  • Inger Kisby, Herts and Essex High School
  • Just a quick note to say that we use a lot of your starters. It is lovely to have so many different ideas to start a lesson with. Thank you very much and keep up the good work.
  • Kerri Smith, Fish Creek Primary School, Australia
  • This site is just brilliant to use with my interactive whiteboard! We do the current day, plus a couple of oldies at the start of each maths session. It really motivates my boys, in particular, FANTASTIC!!!
  • Daisy And Ole, Year 6, Beckley Primary
  • This was a really good warm up.
  • Merry, Australia
  • These are great but do you have the answers somewhere..I am new to this website and just learning how to use it. Some more suited to Junior primary children would be great!
  • Transum,
  • Thanks for your comments Merry. Scroll down the page to find the answers which are available to teachers, parents and tutors when they are signed in to a Transum subscription account.
  • Miss Reakes, West Island School, Hong Kong
  • My Year 10 students were asked to add up their 6 differences. They got very excited both when the answers were being revealed and especially when we were counting down through the errors to reveal the most accurate student!!
  • Mr Blake, Herne Bay Juniors
  • My year 6 Maths group really love these starters. Keep up the good work.
  • Transum,
  • Good to hear that you find the starters useful. Don't forget that many of them are generated randomly so refreshing the page shows different numbers. This makes them useful to revisit and practise skills and techniques learned. The answers to the starters appear further down the page. It's great to receive your feedback!
  • Sylvain - Year 6, Charnwood Primary School
  • More questions or the option to change the shapes would be good.
  • Omoregie Lucky, Nigeria
  • The starters are great. My students love them.
  • Mrs Dodd, Garth Hill College
  • Great warm ups.

It is only when they do this activity a second time that they will have the opportunity to practise those strategies. That is when the learning is consolidated.
