Re-sharing from CPF National (https://cpf.ca/en/event/virtual-story-time/)

Virtual Story Time with Rhéal Allain: Sunday, February 26th @1pm EST 

Join Professor Rhéal Allain, a French Second Language (FLS) professor at the University of Ottawa for a Bilingual Virtual Storytime session on Sunday, February 26th, from 1-2pm EST. Professor Allain has been teaching FLS all of his life.

In this session, participants will learn about Bilingualism in Ottawa and will be able to practice their French in this interactive virtual session. There will be opportunities to ask questions as well as draw so please tune in with some paper and crayons or pencils. PDF/virtual access to the books will be emailed to all participants following the session. The content is most appropriate for ages 2-7, but all are welcome to listen and learn. Participants will receive a zoom link by email prior to the event. Register for free now! 

Previous Session Materials shared with me by CPF National:

"Le ciel me sourit/ The Sky Smiles at Me" by Candace Amarante and "Skin Again" by Bell Hooks, both of which are available in French and English. Candace also recommends "Each Kindness" by Jacqueline Woodson, which we highly recommend.

Also, mark your calendars! Our upcoming story times will take place on Sunday, February 26th, and Sunday, March 5th. You can find the event details and registration links on our website:

Our March 5th session with Madame Amy will have some fun movement activities that are perfect for younger kids!

 

Using Geoboard to Prove Pythagorean Theorem and more

I had a fantastic experience teaching my 8-year-old about the Pythagorean theorem using a Geoboard, we are able to come up a very simple visual proof of the theorem. One can see the area of the outside square is: (a+b)2, but it also equals to 4 right angle triangles (all of them the same size, just different orientation, each triangle has area ab/2) and one small square, whose area is c2 for a total of c2+2ab, hence (a+b)2 = c2 + 2ab, so it's easy to see a2+b2 = c2.

After she learned about square roots using IXL, I was able to show her how to apply the theorem to find the distance between two points on a coordinate system, particularly lattice points. 

One of the things that Geoboard is good about, is to visually create length of special square root, such as √2, √5, √10, √13, √17, etc... and squares with areas 2, 5, 10, 13, 17, etc. It's really fascinating. My child is eager to solve questions related to square root, which is ranging from grade 9-11 IXL questions. I found out using Geoboard is the best approach. 

I used a Geoboard Chrome extension to demonstrate how to use the backtrack algorithm to place 10 points on a 5x5 Geoboard's lattice points in such a way that each row, column, and diagonal would have 2 points. While this may seem complex, I found that using a physical Weiqi board, a Chinese game, made it much easier to execute the backtrack algorithm steps for this particular exercise.
