This problem has been designed to work on in a group of about four. For more details about how you might go about doing this, please read the Teachers' Resources.
You are organising a school trip and you need to write a letter to parents to let them know about the day.
You will need to print off and cut out the information cards.
Share the cards out between the members of the group.
In your group read through the cards and use the information on them to write the letter. You may find that some of the information on the cards is irrelevant!
We would love to see the letters that you write, so please send them in and describe how you tackled the activity.
This activity is taken from the ATM publication "We Can Work It Out!", a book of collaborative problem solving activity cards by Anitra Vickery and Mike Spooner. It is available from The Association of Teachers of Mathematics.
This problem will encourage learners to organise information, identify redundant information and to check their work.
Many NRICH tasks have been designed with group work in mind. We have gathered together a collection of short articles that outline the merits of collaborative work, together with examples of teachers' classroom practice.
This is an ideal problem for learners to tackle in groups of four. Allocating clear roles can help the group to work in a purposeful way - success on this task could be measured by how effectively the group works together as well as by the letters they compose.
Alternatively, your focus for feedback might be mathematical, for example:
Make sure that while groups are working they are reminded of the need to be ready to present their work at the end, and that all are aware of how long they have left.
If your focus is effective group work, this list of group work skills may be helpful. Ask learners to identify which skills they demonstrated, and which skills they need to develop further.
For a very challenging problem, some groups could try Zin Obelisk, which also requires them to draw conclusions from information.
By working in groups with clearly assigned roles we are encouraging children to take responsibility for ensuring that everyone understands before the group moves on.
An investigation involving adding and subtracting sets of consecutive numbers. Lots to find out, lots to explore.
Roll two red dice and a green dice. Add the two numbers on the red dice and take away the number on the green. What are all the different possible answers?
