MATHS300 |
Each MATHS300 lesson serves two purposes. On the one hand it is a professional development experience offering opportunity to try something new, hopefully in conjunction with your staff, in the knowledge that the notes record the successful experiences of your colleagues elsewhere. On the other hand it is a well trialed lesson plan which provides clear information about 'what to do in maths tomorrow'.
| Years: K - 12 | Time: 1 - 2 lessons |
This lesson is used after students have explored the 'iceberg' of a problem and have related it to the Working Mathematically process. Some Schools use this as a poster displayed in the classroom. Others ask students to paste it to the inside cover of their maths journal.
The lesson can be adapted to any year level. It can also be used following any problem solving investigation. You may like to first use this lesson plan by putting it in the context of Maths300 Lesson 17, Eric The Sheep.

In this text, the lesson is embedded in the story shell used by one teacher who related it to exploring the Mathematics Task Centre Home Base web site. Such a story line suggests a reason for the students to learn to write for an external audience. Other teachers may not be in a position to use the lesson exactly as here, but the story shell is readily modified. Perhaps:
- contacting another school by fax or letter
- writing for the school newsletter
- linking to mathematical history and adopting the approach of writing to a friend or colleague as did the mathematicians of earlier centuries.
Web-based student problem solving teams offer another reason for writing mathematics. Several schools have set up such opportunities, and in some cases this has been a consequence of using common materials from the Task Centre Project.
You will need:
| After class yesterday I was telling one of the other teachers how pleased I was with the way we worked on ... . She told me there is a home page for problem solving on the World Wide Web, so I looked it up last night. |
| You might like to look this up at home. You click on the logo to start and then one of the links is called Iceberg Information. Our problem wasn't there, so, since you did so well with it I thought we could plan a report today and submit it for others to use after we write it up. |
| Great. Now could you think of some headings which would help us organise what we will write? A heading should be just three or four words which clearly tell you the sort of things which will be in the section. |
| OK, let's deal with these one at a time. What are the important parts of the problem which we will need to repeat for our internet contacts? |
| Now I'll give you a couple of minutes to write out your personal version of the problem - just the problem, not its solution. We'll choose one to be uploaded onto the home page. |
| Now what shall we write about what we did? |
| Some teachers use butchers' paper charts in this planning phase. |
Is it important that another class realises that the our problem can be acted out? Is it important to know which person played which part? |
| Now let's try to work together to compose some proper sentences which capture all this information. Angela could you think of a sentence which would start us off? |
| This seems like a good paragraph to us, but perhaps we know the problem too well. How could we test our writing to see if it is clear enough? |
