Ruth Lansdell's Indigenous students from Moonah Primary School have submitted more of their investigations to show us how much they love working in mathematics. Look for Ruth's section in the Indigenous Students link on the left to explore what Luke, Braedyn and Naleea think are Interesting Maths Problems.
Four new cameos this month to celebrate returning to school after summer (in the Southern Hemisphere).
- Tetrahedron Nets investigates a second regular solid. Cubes were explored in the previous task, Cube Nets. The iceberg opens up the idea of transforming objects in three dimensions and, in another direction, number patterns suggested by the net.
- Dominoes involves heaps of place value application, simple addition and use of problem solving strategies.
- Dice Differences is a game situation with a chance basis which leads to an open-ended investigation.
- Crosses uses number tiles 1 - 9 to set up a problem at which even young students can succeed very quickly. But the iceberg involves finding all the solutions and that requires discovering some deeper constraints and applying problem solving strategies.
Read about these Tasks of the Month in Task Cameos in the Iceberg Information link on the left, or click on a photo to go straight to printable information about the task. Add the printed files to your Cameo Collection. There is a cover page for your collection in the Iceberg Information link.
You have probably never thought about it, but I would like you to imagine for a minute just how much goes on in the background to prepare the tasks to the high standard you receive. Consider this example:
- a printed and laminated task card
- two printed and laminated clear plastic grids
So that's one task. Now what about the other 233?
Well 20 copies of each task are always packed, stored and ready to be ordered. Plus a few each of:
- Aboriginal Kit (Mmm 50 totally different task cards in those.)
- 16 Maths With Attitude kits (Oh yeah, the manuals and CDs for those have to be printed.)
- Library Kits (Mmm they have an extra parents' card in each task.) and...
It takes a little longer when you get an order like this one for 16 Library Kits from one Innovations & Excellence Cluster which spent much of last year building home/school relationships through mathematics.
You see, there is an amazing amount that goes on 'Ina the background'.
Task 234, Growing Tricubes, has been added to the catalogue. Previously it has only been available with the Years 9 & 10 Maths With Attitude Chance & Measurement kit because it has been disproportionally expensive to produce - for a start the 16 Tricube pieces in each task have to be imported from England. However, Ina has found a way to manage the accounting so that it is available to all. That's great because it offers heaps of surface area and volume work in primary school with an overlay of quadratic and cubic functions in secondary school. In fact, whatever you can do with Sphinx in two dimensions (see Sphinx Album opposite), you can do with Tricubes in three dimensions.
It seems Maths With Attitude kits are answering a need. Hopefully the need for which they were created. They are designed to support teachers in presenting a detailed, integrated, continuing week by week curriculum grounded in happy, healthy, cheerful, productive, inspiring classrooms in which all students are learning to work like a mathematician.
- 200 have been placed in schools since July 2006
- 215 were sent out between July 2005 and June 2006
- 125 between July 2004 and June 2005
- 52 between July 2003 and June 2004, when we were just beginning to create them
Evaluations from these Professional Development days are always positive. The first three programs for 2007 are in the diary. See Maths on the Move link on the left. Other groups have made contact and are making choices. We will take these workshops any where at any time - as long as we can fit the visit into the diary. Don't leave your run too late.
One of our colleagues has contacted us to let us know she is available during part of her week to help schools in this region develop or refresh their hands-on, investigative mathematics curriculum. She is experienced in teaching with tasks and Maths300 and would love to share that expertise. If you are interested contact Doug. Williams doug@blackdouglas.com.au for details.
You have no idea how hard it can be to get plastic farm animals. Sometimes they are just not imported; sometimes you want sheep and you can only get goats. As a result of the latest dip in supply there are now three versions of Task 125 Farmyard Race Day - 125, 125A, 125B. This task is in the Primary Library Kit, so the solution to this task (see Library Kit link on the left), has just been updated to include all variations.
