In our Inquiry unit, What’s the Matter? we conducted experiments on heating and cooling solids and liquids. We also talked about natural and processed materials and made a list of the advantages and disadvantages of using these materials. We conducted the Rot and Remain experiment where we observed how quickly paper, plastic and fabric deteriorated when it is buried in soil.
Now I want to know what you think. What materials should you use to:
Put your shopping in at the supermarket. Why?
Bring your lunch to school in. Why?
Bring your swimming things to school for swimming lessons. Why?
What are the advantages and disadvantages of the material you chose for each of these jobs. Send me a comment at the end of this post and let me know what you think.
We had a great day in Maths this week. First, we read The Great Divide: A Mathematical Marathon. We modeled the division problems in the story using arrays and MAB. Then, we had a go writing our own division stories. Students worked in pairs to make up a story about a race which uses division to reduce the field down to one winner. The creativity showed by the students with their ideas and their division methods was incredible. What was great about this activity was that it was truly open ended. The students’ stories could be as simple or as complex as they wanted them to be. Well done to all the Grade 4s and a couple of Grade 3s. Have a look at the video of the students at work. Next step: challenge the rest of the class with our stories.
