Esti-Mystery
Mrs Stevenson from the Renfrewshire Attainment Team has filmed a video about Esti-mysteries. If you have never done an Esti-mystery before, this is a really great video to watch. Follow the instructions along with the video and pause when you need to, to allow yourself thinking time.
You will need a pencil, paper and 100 number square. An interactive 100 square can be found on this site if you do not have one: https://mathsbot.com/manipulatives/hundredSquare The number square will help you eliminate possible answers.
Extension Task – Here is an Esti-mystery from Steve Wyborney’s website. Have a go and let us know how you do? Do you like Esti-mysteries? Could you make your own Esti-mystery?
