One of my girls who is not mathematically inclined, worked out how we could work out how much soap to melt, to fill one soap mould! Although she didn't know 1ml=1g of water, we soon had a really great discussion about how to work out the capacity of the mould. The next step was to work out how much soap to melt to fill the 6 shapes and how many bars we could make from a 1kg block of melt and pour soap. (I really hoped I had ordered enough!)Then we needed to know how many bars each person could make from the soap we have. Nothing like problem solving in a real context!
The classroom has been filled with aroma of lavender as two boys are using the microwave to gently complete drying the lavender heads we will be using in the soap. We are all feeling very calm.
We also had an interesting conversation about using food colouring in the soap! The resulting PMI showed good thinking and yes we are using blue food colouring in our lavender soap.
Here is a movie two of the girls made about soap making:
This is a great example of the value of using ICTs in classrooms. There has been a huge amount of planning and decsion making involved in producing it. The process of creating a visual text has involved brainstorming, using a storyboard, taking and selecting photographs, proof reading and editing text. The girls also had to be succinct in presenting their ideas. The key competencies have all been covered in this cameo.
