10,000 of Something

Posted April 30, 2013 By jzraskin@gmail.com

Extending from our study of place value several students have taken on the challenge to show 10,000 of something… anything. As they complete these shares they’ll be using fotobabble to publish them to the 2R Twitter-feed (viewable on the left sidebar of our blog). As a taster… Here is one by Lars, completed this morning! Follow the 2R twitter feed for upcoming examples!

What is Balanced Leisure?

Posted February 7, 2013 By jzraskin@gmail.com

This week was Digital Citizenship Week at YIS. Across the school, students were exploring what it means to be a citizen in an online world. In 2R we spoke to a degree about online safety, and different students online habits, but it was in exploring ideas of finding balance that we really got into it.

At present we’re knee-deep in a Unit of Inquiry looking at how lifestyle choices that people make can affect their health. As part of this, we were learning about leisure, and considering the different ways we choose to spend our free time.

On Monday, Ms Elif came into our class and shared a video. Take a look at it!

After watching it a few times we decided that the video was about how we sometimes ignore the people we’re with, when we’re using digital devices. Most students had had experiences of this that they wanted to share.

We used a See, Think, Wonder thinking routine to explore what we saw in the video, what we thought it might be about and what questions we had.

We spoke about how maybe the ideas around balanced nutrition that we’d been exploring could be connected with ideas around balanced leisure time. When the counselor, Ms Kumamoto, came to join us we did some thinking about the advantages and disadvantages of screen-based and non-screen based leisure choices.

We decided that we would track our leisure time for a few days to get an accurate understanding of how balanced our own behaviours were. So, over Tuesday and Wednesday students tracked the details of their leisure activities. We considered whether they were indoor or outdoor, screen or non-screen based, exciting or relaxing, done alone or together with others, and how we felt when we’d completed them. We also kept track of how many minutes we spent doing each, which was a great way to learn a bit about elapsed time.

After two days of recording, on Thursday students analysed their leisure habits, looking for patterns. Many students observed big imbalances in terms of how much of their leisure time was spent indoors vs out, or doing screen-based vs non. Armed with this better understanding of our leisure habits, some students reflected on what goals they could set to better balance their leisure time. Other students just realised that with all of their after school commitments they felt they had far too little free time to begin with.

On Friday, we’ll be sharing some of what we learned about balancing our leisure time at an assembly. Seven 2R students decided that they wanted to participate and sat down to plan what they wanted to say and how they would share the responsibilities. Stay tuned for more. Now go and enjoy some non-screen leisure too!

MICHAEL YMER MATH WORKSHOP FOR ELEMENTARY PARENTS

Posted January 15, 2013 By jzraskin@gmail.com
Date: Monday – January 21, 2013
Time: 7:00 PM to 8:30 PM
Location: Loft
Michael is a specialist mathematics consultant from Melbourne, Australia. He is involved in many professional development programs in schools across Australia and Asia. Michael is an enthusiastic and entertaining presenter who has a clear and practical approach to the challenges that confront schools and parents in mathematics. On this evening Michael will address the following issues:What is my child learning in mathematics?
How can I help my child become an efficient problem solver?
How do children best learn mathematics?
How can parents promote quality thinking and learning?
How can I help my child in mathematics?

After the success of last year’s well attended, informative, and fun parent workshop, Michael Ymer is back again to help parents understand the role of Mathematics in our everyday lives. He will also focus on helping parents in understanding the way Mathematics is taught in schools. He will, with true Australian humor and poise, help us uncover what inquiry is, how inquiry can help us all become better mathematicians and how parents can help their children to be natural mathematical inquirers at home.

To register for this event please email our elementary Mathematics Coordinator, David Goddard goddardd@yis.ac.jp to confirm your attendance.

The first unit of inquiry grade two embarked on this year was a study of ways in which we are enriched by our own cultures and the cultures we connect with throughout our lives.

As we began asking questions along a line of inquiry exploring similarities and differences between cultures, we struggled with ways to collect and make sense of the answers.

Among the Mathematics learning outcomes for this year, in the Data Handling strand, is the Conceptual Understanding that Data can be collected, organized, displayed and analyzed in different ways. This was a perfect opportunity to bring together Maths learning with our Inquiry studies.

Students began by building on the sort of questions that had been bubbling up already by brainstorming a wide range of curiosities about differences and similarities amongst families and cultures.

I challenged them to find answers to their questions from our class. Each student chose a different question of personal importance or interest and used their previous knowledge of collecting answers to their questions to go about surveying their peers.

Each student had recorded the data in different ways so we took some time to analyze the features of their data collection systems and students explained the thinking behind their strategies. One student recalled having made graphs of data in the past, as a way of clearly presenting the information, so students discussed what they remembered about this, and had a go at making their own from the data they’d collected.

We compared the varied graphing strategies students had used and the conclusions they had been able to draw from their data. We followed this with a discussion of what we thought some of the most successful features of data collection systems had been, that had allowed for us to most clearly, accurately and quickly collect information.

In small groups, students worked together to build new data collection tools, based on our previous discussions and examples, to most effectively get answers to the questions they were posing.

 

Students collaborate on a data collection tool.

With these complete, groups presented their tools to the class and used the questions and suggestions to refine their tools before trying them out.

Students present their collaboratively-created tools for class questions and suggestions.

Finally, it was time to put our team-created and class-critiqued tools to the test, by surveying the class. How accurate, clear and fast would the tools allow our data collection to be?

 

Students test their tools by surveying their peers.

Having collected data with their tools, groups used the Two Stars and a Wish reflection strategy to identify two elements that had worked exceptionally well about their designs, and one feature they could improve upon.

We shared these with the rest of the class and developed a collaborative list of features we all considered key to making a data collection tool as Fast, Accurate and Clear as possible.

Students used this list to support their posing of a final, independent question. They each created their personal, ultimate data collection tool and surveyed the class.

Students apply new understandings in creating their own super-data-collection tools.

Finally, we came back to the discussion of graphing and presenting our data. I introduced the simple graphing features of the Pages application to the class and we looked at how our understanding changed depending on the wide variety of ways we could display the data. Some students considered pie graphs to be most appropriate for communicating their answers, others preferred bar graphs. Each student explained the thinking behind their choices for a way to present their data.

We reflected on our learning through this process as being a design cycle. We looked at our original data collection tools and graphs, how they’d been improved through discussion and group work, then further improved by presentation and critique, tested by trying them in action, better understood through reflection and sharing our learning and finally improved in our individual final tools and graphs.

In reflection, one student mentioned proudly how much better his final survey and graphing worked, compared to his first attempt. Yes, agreed another, but we could still make them better next time…

Mad Science Team Time!

Posted October 14, 2012 By jzraskin@gmail.com

This past week’s Team Time, always a favourite in second grade, took on a whole other shape when it turned into Mad Science Team Time!

In honor of our new unit ‘Climate affects people’s lives‘, the grade 2 students enjoyed weather-related science explorations and experiments.

Students had the choice of investigating wind, water, or air pressure!

Enjoy the slideshow…

Student Led Conferences

Posted March 22, 2012 By jzraskin@gmail.com

One of my favourite days of the year! It’s always such a pleasure to see my students and their families sharing the fun of learning experiences.

Students thoughtfully proposed a huge range of potential learning activities in a Wallwisher brainstorm. Then we developed the materials we would need to share the most popular and appealing with our families. Finally, students used their “passport” to organize themselves for the day, planning their first and second choices for each strand of learning.

On the day of the conferences, students were completely independent, enjoying sharing this time and learning with their parents… All I did was sit at my desk, give them a heads up on how their time was progressing now and then, and take a few photos!

It was great to see so much laughter, sharing and enjoyment. Check out the gallery:

A Lesson from G4 About Division

Posted November 19, 2011 By jzraskin@gmail.com

Grade two got an invitation we couldn’t resist… Joining 4G to learn about division! Division isn’t something that we formally study in G2, but it’s great to get a window into new kinds of mathematical thinking, and great practice for the G4s to try to transfer their understanding by teaching us.

Please note the music was choice of the G4s!

Snowflakes

Posted November 16, 2011 By jzraskin@gmail.com

Today’s post is from Airi, in her own words…

In 2R we read a book called Snowflake Bentley. There was a boy that liked snowflakes and when the boy got bigger he drawed lots of snowflakes. And there was lots of kinds of snowflakes. 2R made some snowflakes and we put it at the window.

What did you learn about snowflakes?

There’s three or six branches at the corner.

Lots of snowflakes.

Weather

Posted November 2, 2011 By jzraskin@gmail.com

Today’s post is from Ellie, in her own words.

We went to the weather observatory a couple of weeks ago. We found out about different clouds, what weather different clouds can make.

What have we been doing this week about weather?

We listed some measurement tools that you can use for weather too. We learned about snowflake Bentley, who was very interested in snowflakes. No snowflakes can be ever the same. And I learned that if you count from the lightning until the thunder comes you know how far it is by miles by my book club book, Thundercake.

I learned a lot about weather from my book club books.

So many visitors to 2R…

Posted October 6, 2011 By jzraskin@gmail.com

The past few weeks have seen so many visitors come to 2R to enrich our classroom life. I felt it was time to do a quick photo-summary of some of these interactions with our community, and to share our great learning experiences!
