There have been announcements about it every morning for the past week, but I wanted to remind everyone that tomorrow morning the entire school population will be outside, in our Spirit Teams, participating in the annual Jump Rope for Heart event.
Students will rotate through a number of stations, with opportunities for rest in the shade – but tomorrow promises to be hot and sunny – I’d recommend light clothing, running shoes (for all that jumping!), sunscreen, hats and water bottles to keep everyone cool, protected from the sun, and hydrated.
Also – we’ve been asked to wear red to show support for the Heart and Stroke Foundation – break out your Valentine’s Day colours 🙂
Today we worked on a problem – can you build rectangles that have the same area, but different perimeters? Turns out you can – we built rectangles and squares using 36 square tiles – so every shape had an area of 36 square units, but their perimeters were all different. Here’s an example of the students’work, showing the shapes with the same are, but different perimeters:
Now we know that shapes can have the same area but different perimeter- but we were left wondering this – can 2 shapes have the same perimeter, but a different area? The were left to ponder this, with the challenge to prove or disprove it.
Here they are at work this morning:
Capture the array is a game where 2 players roll an 8-sided die to determine the dimensions of a square or rectangle. For example, if I rolled a 4 and a 9, I would draw an array with base 4 and height 9 – and write in the area (36 square units). Players take turns rolling the dice and drawing their shapes on a 20 x 20 grid. The game is over when one player cannot find a spot to fit his/her shape on the grid – the last player to place a shape on the grid wins.
Those who have mastered their multiplication facts have an advantage, because you are allowed to change the dimensions of your rectangle, as long as the area remains the same. For example, if I couldn’t fit a 4×9 rectangle on the grid, but could find a spot for one that was 3 x 12, or 6×6, I could play it , because the area would still be 36.
After our visit from the Humane Society, Heidi and Sophie wanted to make a difference and help animals in need! They have organized their own fundraiser to help our local animal shelter. On June 12th, join Heidi and Sophie for the “Double Digit Dog Walk” which is a walk around the Avon River. All donations will be given to the Humane Society. For more information, please check out Heidi’s and Sophie’s blog!
