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?

Magic Squares Challenge

Have a look at the Maths problem below.  Each of the lines vertically, horizontally and diagonally must add up to 15 but you can only use the numbers given once.  Can you complete the challenge?  If you started with all blank squares and used the numbers 1-9, could you solve in a different way?

Finished?  Photograph your work and send to your teacher. Why don’t you login to Sumdog and compete in Renfrewshire’s Sumdog Competition – Ends Thursday!!

You could do addition, subtraction, multiplication or division sums, or try a mixture!

Division is way to explore items being shared equally.
