What do all these stick pictures have in common?
Yes, they are all made from sticks….anything else you notice?
The sticks have been cut to specific lengths? Correct: 10cm, 25cm, 50cm can be seen in all these photos.
When you add up the total length of the sticks used in each photo, they should all equal 3 metres. A clever little problem solving challenge for a class to undertake.
- If you want to up the level, then encourage children to convert their counting from centimetres to millimetres and metres.
- It can become a more interesting investigation if children decide to change an aspect of the challenge such as changing the total length of the sticks. How would your class adapt this problem?
- Cut sticks can be bought from Cosy or Muddy Faces. Better still why not get your class to cut their own during the winter months as a woodland maths challenge.
- A nifty homework challenge can be to get each child to measure out a length of cardboard. They take this home and have to collect a bundle of x amount of sticks of this length. Remember to provide advice about collecting sticks in an environmentally sustainable way in line with the access laws of your country.
